    Which operating system do you have? Windows XP or other? Do you have a driver CD or disk that came with your flash disk?

Try to download some new USB drivers, or update your old one. That may fix your problem.

Dell dimension will not recognize a new hard drive or boot from windows disk. all conection seem OK


Hi tomcartp...

Go to Device Manager
To get to Device Manager you will:
Right click on My Computer>Properties>click the Hardware Tab>Device Manager.
After you are in Device Manager look for your MP3 player or Unit.
Here you should see no "Yellow" exclamation points.
If you do they they are telling you that you have a device conflict.
If you currnetly have your unit plugged in, you may notice the "unknown device" which would be your Player or Unit.
If you unit has an exclamation point by it, then you will need to click on it and delete it.
After you remove all devices with conflicts then click on refresh and search again for your MP3 player/Device.
The computer should install your device this time and solve your problem with connection of the MP3 player/Device.
Please take time to rate me thumbs up.

Tip

My USB 'Whatever' will not work


This not is not for USB flash drives, microphones, mice, anything that does NOT have an install disc at the time of purchase.

Most USB issues are caused by installing a USB device BEFORE you install the driver disk.
In all cases, if there is a driver disk, insert the disk first and wait for the install program to ask for the device. Then plug it in.

If you have done the faux pas above, all the installs in the world will not fix it. You MUST remove the USB driver. Use Device Manager. In XP, this is found by right clicking my computer and selecting properties. In properties select the hardware tab and choose 'Device Manager'.

Stop here. If you have no idea what I wrote, review 'Device Manager' on the Windows Website or ask a KNOWLEDGABLE friend for help. See http://support.microsoft.com/kb/310123.

Now, select the USB device, while it is plugged in to the USB port, and right click. Select 'Uninstall'. Remove your USB device when device manager is done.

Close Device manager and all the other windows. Start your USB install from scratch, without the USB plugged in untill the install asks or completes.
I have ALWAYS had succesfull installs with this method.

Acer eLock Management
Acer eLock Management is a security utility that allows you to lock your removable data, optical and floppy
drives to ensure that data cannot be stolen while your notebook is unattended.

Removable data devices - includes USB disk drives, USB pen drives, USB flash drives, USB MP3 drives,
USB memory card readers, IEEE 1394 disk drives and any other removable disk drives that can be
mounted as a file system when plugged into the system.

Optical drive devices - includes any kind of CD-ROM or DVD-ROM drives.
�� Floppy disk drives - 3.5-inch disks only.
�� Interfaces - includes serial ports, parallel port, infrared (IR), and Bluetooth.
To activate Acer eLock Management, a password must be set first. Once set, you can apply locks to any of the
devices. Lock(s) will immediately be set without any reboot necessary, and will remain locked after rebooting,
until unlocked.

You can try this:

You can reset the system to its default settings (all devices unlocked) by removing the password (leave the password fields blank when changing the password).

You also may be able to simply uninstall the e-lock software in add remove programs.

Is there an icon in your system tray that may allow you to disable e-lock?

How to insatall a web cam in to the pc


If you have already plugged the USB device into the system before loading the driver, Windows will install a driver for you call “unknown device”. The steps to fix this are to plug the USB device into the computer, then click <Start> <Control Panel> then go into <system>. In there you will need to find the device manager under the hardware tab. When you are in the device manager, you will see a list of all of the hardware install in the computer. Most of them will have the + in front of them showing all is good. There should be one that stands out and most likely, this will be your USB device. At this point you will want to right click the USB device and click remove. Unplug the USB device from you system and reinstall the software. If the software is already install in the system you may be able to just plug the USB device back into the system and it will find the driver.

I plugged my Memorex TravelDrive into my computer. It has always worked perfectly. This time I got the message that the USB device was not recognized and I can't get into my files.


THE FOLLOWING IS COURTESY OF MICROSOFT Help and Support

When you plug a USB device into a Windows XP-based computer immediately after the computer comes out of standby (S3) or hibernate (S4), the computer may not recognize the USB device. When this issue occurs, the USB device may be listed in Device Manager as an unknown device, and you may receive the following warning message:
Unrecognized device has been found.

This issue occurs because, when the computer comes out of S3 or S4, there is a five- to ten-second period when the selective suspend feature of the USB driver will interfere with detection of a new USB device connection. The time period depends on several factors. This includes the following factors:• Host controller hardware
• Attached hubs
• Attached devices
• USB driver versions
• Support for USB 2.0
• Additional system hardware or configurations that may change the timing
There may be other reasons that a USB device is not detected

Method 1
loadTOCNode(2, 'workaround'); After the computer comes out of S3 or S4, wait five to ten seconds before you plug the USB device into the computer or hub.

Method 2
After the computer comes out of S3 or S4, unplug the USB device, and then plug the device back into the computer or hub.

Method 3
Use the Device Manager to scan for new hardware. Follow these steps: 1. Click Start, click Run, type Devmgmt.msc, and then click OK..
2. On the Action menu, click Scan for hardware changes. This causes Windows to recognize new devices.
3. Close Device Manager and Control Panel.

Method 4
Disable power management of the USB hub.
Note If you perform the following procedure, you may also reduce the battery life on a portable computer.
To disable power management on the USB hub, follow these steps: 1. Click Start, click Run, type devmgmt.msc, and then click OK.
2. Expand the Universal Serial Bus controllers node, and then follow these steps for each USB Root Hub that is listed: a. Right-click the USB Root Hub, and then click Properties.
b. Click the Power Management tab.
c. Click to clear the Allow the computer to turn off this device to save power check box, and then click OK.

Try restarting the computer with the device in. Sometimes if you clear the memory that might help (stating the machine without memory then put it back and start it again).

Fujitsu seimens scaleo P


Easiest way is to find the drivers through the "connect to internet" option which you get once you click on update/re-install drivers in the device manager. Sometimes this process does not work, so in that case you go to fujitsu site, support,choose your PC model and download drivers. Another option, go to driversguide.com, specify your PC model & download drivers.
