Service port is as another posted, just under headphone jack on right side where all the in-out jacks are.

There is a thin mylar film you need to peel out of the way. I used fingernail.

The computer can not recognize drive (unknown USB device).


Method 1 - Unplug Computer So how did I finally fix the problem? Well, if you are lucky, it's a super simple solution! Try this method first and if it works, you'll have saved a lot of time.
Simply unplug your computer from the power supply. Yes that is it! Note that this does not mean just turning off your computer using the power button because most modern computers don't actually turn off completely and the motherboard will still get power. This is useful sometimes if you want to remotely wake up a computer, etc.
The motherboard is where all of hardware of the computer connects to, including the USB ports. Sometimes the motherboard needs to be "rebooted" because things can go wrong, i.e. all or some USB ports suddenly stop working. The small microprocessor on the motherboard will reload the drivers and your USB ports should hopefully be recognizing devices again.
So first turn off your computer using the Shut Down option in Windows or pressing the power button and then UNPLUG the PC from the wall outlet. Let it sit for several minutes and then plug it back in.
Method 2 - Update Device Driver If Windows is not able to recognize the device, you may also see in Device Manager that the device shows up as an "Unknown Device". You can get to Device Manager by clicking on Start and typing in devmgmt.msc or by going to Control Panel and clicking on Device Manager.
In that case, you should right-click on Unknown Device, click on Properties, then the Driver tab and then click Update Driver.

If this doesn't work, you can also try to download the driver for your device from the manufacturer's website. If the USB device is just a flash drive, then it's probably not a driver issue. However, if you are installing a USB printer, drawing pad, etc, then it might be worth downloading the driver for that specific device.

Method 3 - Restart & Disconnect USB Devices The next thing you can try is to disconnect all USB devices and then restart the machine. once you have restarted, try to connect the USB device that was causing the problem.
If that particular USB port doesn't recognize it, try another one. If the device is recognized by a different USB port, there could be a hardware problem with one of the USB ports. If no USB port recognizes the device, then keep reading because it's probably something else.

Method 4 - USB Root Hub Another thing you can try is to open Device Manager, expand USB Serial Bus Controllers, right-click on USB Root Hub and then click on Properties.
Click on the Power Management tab and uncheck the Allow the computer to turn off this device to save power box. If you have more than one USB Root Hub listed, you need to repeat these steps for each one.
Click OK and then restart your computer. Try to reconnect the USB device and see if it is recognized. If not, go back to the power management tab for each one and check the box again. If it does recognize the device, then leave them unchecked.

Method 5 - Connect Directly to PC A friend of mine ran into this issue and the cause ended up being his USB hub. He only had three USB ports on his computer, so he bought a hub where he could connect an additional 8 USB devices.
I guess this proved too much for his computer and it just started sporadically not recognizing various devices. After removing the hub and connecting the device directly to the computer, it worked just fine.
We haven't really been able to find any other solution to this problem other than reducing the number of items connected to the hub. Actually, one other solution worked, but it meant having to buy a new USB hub with more power.
If you are having this problem with Windows 8 or Windows 8.1, then you might be in luck. Microsoft has released a fix for Windows 8 not detecting USB devices properly. Make sure to install this hotfix if running Windows 8.
Method 6 - USB Troubleshooter If nothing has worked so far, you can download the Windows USB Troubleshooter Fixit tool. It's a free tool that works with Windows XP, Vista and 7.
You can either have the troubleshooter fix the problems for you or select the fixes yourself. I would just let it fix them for you since the choices can sometimes be confusing and technical for the novice user.
Method 7 - Update Generic USB Hub If you are getting the Unknown Device error in Device Manager, you can also try one other thing. Open Device Manager and then expand Universal Serial Bus Controllers.
You should see at least one item called Generic USB Hub. On some computers, you might see two, three or more of these. Right-click on the first one and choose Update Driver Software.
When the update dialog pops up, choose Browse my computer for driver software.
When the update dialog pops up, choose Browse my computer for driver software.

I have a Memorex Ultra Drive connected via USB to a Windows XP machine. It shows up in My Computer as a folder but then disappears again. It does this repeatedly. The drive is formated as a FAT32. How...


Hi,

As you have described that your Memorex Ultra Traveldrive re-appears repeatedly, indicates that the communication between your computer and your external hard drive is intermittent. The FAT32 format does not produce these types of issues. What we can do first is identify what causes the problem.

Assuming that the hard drive in your Memorex Ultra Traveldrive is in good shape:

Troubleshooting Method #1. Try connecting your Memorex Ultra Traveldrive into another USB port. If the problem persists, use another USB cable for your external hard drive. If the problem still persists, you will have to replace the external casing of your external hard drive. If your external hard drive works with the other USB port perfectly, most likely, the USB port where you originally plug into of your Windows XP machine needs to be checked. That USB port might need some repairing.

Troubleshooting Method #2. Try connecting the external hard drive into another computer and perform the same troubleshooting as Method #1. If your external hard drive works with other computers perfectly, most likely, the USB port where you originally plug into of your Windows XP machine needs to be checked. The USB port might need some repairing.

If the problem only occurs with your Windows XP machine, assuming all USB ports are in good shape, your Windows XP needs to be checked for some software issues.


I hope this works for you. Kindly reply/comment for further assistance. Good Luck!

Hi,

Try these steps:-

  • Unplug the USB cable from the computer.
  • Turn the unit off and then back on again.
  • Plug the USB cable into your computer.
  • The unit either automatically goes into USB Mass Storage Mode or displays USB Mass Storage Mode as an option on the screen.

Note: If your computer still does not detect the unit, make sure that you plug the USB cable directly into the computer USB port and not the USB hub. If the cable is already plugged directly into the computer, try plugging it into a different port.

Also, in some cases the operating system does not support the device. Try upgrading it to the next higher level. In most of the cases windows Xp service pack 2 does not recognise this Garmin device. Try upgrading it to service pack 3.
If you are still experiencing the problem then you will need to contact Garmin for repair.
Thanks for using Fixya.
Good Luck and have a nice day.

What you could do is first check in the device manager. Go to control panel and click on system. From there on the top click on hardware. Then click on device manager. Look for any icons that would have an X, ?, or ! on it. If they do right click then click update.

USB ports not working


Method 1: Use Device Manager to scan for hardware changes loadTOCNode(2, 'resolution'); Use Device Manager to scan for hardware changes. After your computer scans for hardware changes, it might recognize the USB device that is connected to the USB port so that you can use the device.

To scan for hardware changes, follow these steps:
  1. Click Start, and then click Run.

    Note If you are running Windows Vista, click Start, and then use the Start Search box.
  2. Type devmgmt.msc, and then click OK. Device Manager opens.
  3. In Device Manager, click your computer so that it is highlighted.
  4. Click Action, and then click Scan for hardware changes.
  5. Check the USB device to see whether it is working.
If scanning for hardware changes fixed the problem, you are finished. If this method did not fix the problem, go to Method 2.
Method 2: Restart the computer loadTOCNode(2, 'resolution'); If scanning for new hardware did not fix the problem, try restarting the computer. After the computer has restarted, check the USB device to see whether it is working.

If restarting the computer fixed the problem, you are finished. If this method did not fix the problem, go to Method 3.
Method 3: Disable and re-enable the USB controller loadTOCNode(2, 'resolution'); Use Device Manager to disable and re-enable all the USB controllers. This lets the controllers recover the USB port from its unresponsive condition. The USB controllers represent the USB ports in Device Manager.

To disable and re-enable the USB controllers, follow these steps:
  1. Click Start, and then click Run.

    Note If you are running Windows Vista, click Start, and then use the Start Search box.
  2. Type devmgmt.msc, and then click OK. Device Manager opens.
  3. Expand Universal Serial Bus controllers.

    Note You might have to scroll down the list to find this item.
  4. Right-click the first USB controller under Universal Serial Bus controllers, and then click Uninstall to remove it.
  5. Repeat step 4 for each USB controller that is listed under Universal Serial Bus controllers.
  6. Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.
  7. Check the USB device to see whether it is working.

MS optical desktop 700


try one of the method below:
Method 1: Try different ports loadTOCNode(2, 'moreinformation'); Warning If you have to change a PS/2 connection, shut off the computer, make the changes, and then restart the computer. Do not plug a PS/2 device in the PS/2 port while the computer is running.

To determine whether the problem is related to the ports on the computer, use only the two cables that are included with the wireless desktop receiver, or the single cable that is included with a mouse.
USB keyboard and USB mouse loadTOCNode(3, 'moreinformation'); If the USB cable is currently connected to a USB hub, disconnect the device from the hub, and then connect it to a USB port on the computer. If your device is already connected to a USB port on the computer, try to connect the device to a different USB port if one is available.

Note Only one USB connection to the computer is required, even if your device has two USB plugs. If the problem persists, disconnect other USB devices and connect only the USB plug from the receiver to a USB port on the computer.
PS/2 devices loadTOCNode(3, 'moreinformation'); If your devices are connected to PS/2 ports on the computer, verify that you have the following configurations: • Verify that the USB plug for your mouse is connected to the green USB-to-PS/2 adapter and that this adapter is plugged in the mouse PS/2 port on the computer. The mouse PS/2 port on the computer may also be green. If you are not sure which PS/2 port is the mouse PS/2 port, see the documentation that came with the computer. • Verify that the USB plug for the keyboard is connected to the purple USB-to-PS/2 adapter and that this adapter is plugged in the keyboard PS/2 port on the computer. The keyboard PS/2 port on the computer may also be purple. If you are not sure which PS/2 port is the keyboard PS/2 port, see the documentation that came with the computer.If you have to change your configuration, shut off the computer, make the changes, and then restart the computer. If your mouse or keyboard has both USB and PS/2 connections, try using the other connection.
PS/2 keyboard and USB mouse loadTOCNode(3, 'moreinformation'); Verify that the USB mouse is plugged in a USB port on the computer and that the purple keyboard PS/2 plug is connected to the purple PS/2 port on the computer. If you have to change the PS/2 connection, shut off the computer, make the changes, and then restart the computer.

Method 2: Install fresh batteries loadTOCNode(2, 'moreinformation'); Both the wireless keyboard and the wireless mouse rely on AA alkaline batteries for power. If the problem persists, install a fresh set of batteries in the device that you are experiencing problems with.
uparrow.gifBack to the top
Method 3: Resynchronize your device to the receiver loadTOCNode(2, 'moreinformation'); To resynchronize the mouse or keyboard to the receiver, follow these steps.

Note When you synchronize the mouse or the keyboard with the receiver, put the device near the receiver and put other wireless keyboards and mouse more than six feet away. 1. Press the button on the receiver, and then verify that the light on the receiver starts to blink. 2. If a dialog box appears on the screen in several seconds, follow the instructions that appear on the screen.

Otherwise, go to the next step. 3. Press and release the Connect Channel button on the bottom of your mouse or keyboard. 4. Check the green light on the receiver. A steady green light means the synchronization was successful. If the problem persists, try steps 1 through 4 again.
uparrow.gifBack to the top
Method 4: Install the latest software loadTOCNode(2, 'moreinformation'); If you are troubleshooting a wireless mouse, download and install the latest Microsoft IntelliPoint software. For more information about IntelliPoint software, visit the following Microsoft Web site:
http://www.microsoft.com/hardware/mouseandkeyboard/Download.mspx (http://www.microsoft.com/hardware/mouseandkeyboard/Download.mspx) If you are troubleshooting a wireless keyboard, download and install the latest Microsoft IntelliType software.

Method 5: Clean the mouse lens loadTOCNode(2, 'moreinformation'); This problem may occur if you are using an optical or laser mouse and the lens on the mouse is dirty. To clean the lens of an optical or laser mouse, follow these steps: 1. Use a dry cloth to clean the bottom surface of the mouse. 2. Check to see whether the mouse functions correctly. 3. If you see dust on the bottom of the mouse, use a can of pressurized de-ionized air to blow away the dust on the lens. 4. Check to see whether the mouse functions correctly. 5. If the pressurized air canister is not available, blow dry air on the lenses by using your mouth one or two times. 6. Check to see whether the mouse functions correctly. 7. If these steps do not resolve the problem, use a cotton bud to clean the lens without scratching it.
