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 toshiba satellite a 300-02w laptop.my web cam suddenly stop working. and i tried with update driver still problem is same. i found one thing that my webcam not listed in device mangaer so how can i...


Hello,

First, lets try to see if the webcam itself is bad. The easiest way to do this is connect it to another pc, any pc. If it does not work on a different pc then we know the webcam is fault and needs to be replaced.

If it does work, then we know we may have a setting issue. It may be listed in device manager as an unknown device. Have you looked through all the devices including unknown devices to see if it is listed?

You can try a different USB slot on our computer as the one you are using is experiencing problems.

When you connect the webcam to the computer, do you get a message such as "hardware found"?

If this is a built in camera then you can obviously ignore these steps.

Regards,

After 7 install two unknown devices shoe up under usb and no usb devices will work


If you have the motherboard CD the Vista drivers should work in Windows 7. Try updating the drivers for the two unknown devices from the motherboard CD. If you don't have the CD you should be able to download the USB chipset drivers from your motherboards manufacturers website.

Hi I have tom-tom one XL (no sd card) model, it wont turn on,replaced the battery then ok next time nothing. But if I unplug the battery and connect again ok until I switch if off, I have to unplug battery...


Hi happyivan8 i know tomtoms answer to this problem is to plug it in to the computer for a few hours but thats not really a fix, just an added pain in the rear.

i have 2 of these and one worked good after i updated it but the other still has the same problem and will only start after i charge it via the usb cable or unplug and plug the battery back in.

try updating it through tomtom home but it may or mayneo solve the problem. if you have already tried the update and that didnt help, i dont know what else you can do other then use it for target practice like im going to.

you can get tomtom home HERE if you dont have it already!

It needs to be reset in your BIOS. But first try right-clicking on the USB in Device manager and then click on properties..follow those instructions first. If still not working then you then upon startup you should see a message that says press "F>>to enter setup>. Once inside BIOS on one of the pages look for ports..toggle anything and all boxes that have USB in front of them to "ENABLED".. that should fix it,if not then you may need to buy new ports..but that is a different subject..let me know if you have any questions.

Reinstall the printer over and over again


This is a common problem I got with many HP installer: Scanner, Printer, DVD drives always when using USB.
I had request to reinstall HP device every time I used scanner on XP home SP1, Update to SP2 and latest HP driver fixed the issue.
recently HP3050 was reinstalling with a new USB address after every power off. Upgrade to SP3 and changed model to HP1319 fixed.
Check your security settings: HP installer tries to install some hidden programs (rootkit?) clearly conflicting with some security protection (specially if you are using some hidden program installer as AOL or Symantec)).
1) check all your security protection: AV, Firewall, policy you set, disable what you do not need.
2) update your windows installer
be sure you have an update windows (are you on XP SP1?)
3) I recommend you uninstall all your USB printer and remove all your HP device:
Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall any HP or unknown device under Printers.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.
When this is done, reboot TWICE.
4) reinstall your Prt driver BEFORE connecting the printer

Let me know is this is fixing your issue.

Possibilities:
1) One of your USB devices have faulted, or is causing a resource conflict (or similar)
-- Remove all USB devices, and reboot.
2) Your USB chip/ports have been damaged.
-- Find a spare HardDisk or bacjup your data and re-install Windows and see how that goes.
3) Your Power Supply Unit (PSU) isnt supplying enough power to your PC (usually caused by a Video card upgrade). Try a more powerful PSU ... 400watts should do the trick
4) Bad memory (RAM) can cause wierd problems. run memtest for an hour to make sure your memory is ok





It seems that many people are still getting the 'USB Device not Recognized' problem from time to time. Unfortunately there is no easy fix.
Firstly, it's recommended that you make sure every one of your motherboard drivers are completely up-to-date, but you probably already knew that.
In XP, after a USB port isn't used for a long while the USB driver built into the OS sets the OHCI controller to suspend. When you plug a device back in, it can sometimes fail to 'wake up' properly. This problem was supposedly fixed in SP1 but there is a related registry hack that may still be able to help.
Run regedt32.exe and navigate to;
HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Services\Usb
Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. Then restart the PC.
A long shot perhaps, but I recall having similar problems with a USB hub built into my Microsoft keyboard and adding this key seemed to solve it. It wouldn't hurt in trying .
Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force XP into refreshing the USB driver stack.
Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software. Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;
1. USB peripheral devices (printers etc.)
2. HID and/or Composite USB (Human Interface Devices) You're using PS/2 input devices so you may not have this entry.
3. USB Root Hub(s)
4. USB Host Controller(s) (Universal or Enhanced Host Controllers)
Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.
Hopefully some of this may be of help, let us know how you get on.
