Hello,

What OS are you working with?

Is this a USB Palm?

Is this a USB Printer?

Did you turn on the palm first and set it up? (New Palms need to be calibrated out of the box before they will sync).

Once we know your OS, we can go from there. Later moderators reading during the day might move your post to the OS section once you reply.

Did you first use the hardware under Windows 98 and now you have Windows XP maybe? If so then you'd have to download new drivers for the computer to recognize them.

I found a fix for USB devices not working, actually came from Microsoft technicians. Apparently there's a problem with the Intel USB chipsets going flakey

Step 1: Remove Hidden Devices

1. Open a Command Prompt.
2. Type "set DEVMGR_SHOW_DETAILS=1" (without quotation marks) and press Enter.
3. Type "set DEVMGR_SHOW_NONPRESENT_DEVICES=1" (without quotation marks) and Press Enter.
4. Type "start devmgmt.msc" (without quotation marks) and click press Enter.
5. Click View. Click Show hidden devices.
6. Click "+" to expand devices, Unknown devices and USB devices.
7. Are there any devices and unknown devices (including grayed out devices)? If so, please right click it and click Uninstall them.

Step 2: Remove all oem*.inf files

=========================

1. Click start and click run then under the run line type in the command "cmd" (without the quotation marks)

2. In the command line, type in the following (without the quotes) and press enter after each command:

"cd \windows\inf"
"ren infcache.1 *.old"
"ren oem*.inf *.old"
"del C:\windows\setupapi.log"
"exit"

Step 3: Removing all entries under HKEY_LOCAL_MACHINE/Enum/USB that start with VID using REGEDIT.

==================================================================

Removing the VID entries from the registry will cause them to be redetected at restart.

CAUTION: If you have a USB keyboard, mouse, scanners, and other things you know are working, do not remove the VID entry for these devices, otherwise, Windows may not restart correctly.

1. Click Start and click Run. Type regedit and click OK. The Registry Editor window will open.

2. Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\USB.

3. Highlight and delete all the VID_.... entries for usb devices that you cannot identify. Remember not to delete the entries mentioned above.

You may not have permssion to delete keys, do the following.
Permissions may be set allowing the deletion of the VID_ entries by following the steps below:

a) Right-click the key to be deleted, and then click Permissions. The VID_... Permissions window will open.
b) With Everyone highlighted in the Group or User name section, select Full Control in the Permissions section.
c) Click Apply, and then click OK.

5. Restart your compuer.

Step 4: Reconnect the USB device that was not previously working. Windows should automatically rerinstall the drivers.

This worked for me and hope it helps you out. Good luck with it.

I'd also suggest that you download and install all available Windows Updtaes, if you haven't done so already, and also download and install any available motherboard chipset drivers for your system or motherboard.

Some of the Windows updates correct USB problems

Need to install Windows again?

hey guys! i tried the above, and it didn't work. im using windows xp on a new notebook, and have recently bought a western digital hard drive and i keep getting an error message.When I first got the device, it worked fine. However I soon noticed that it would occasionally not work. And I would get the message "one of the USB devices attached to this computer has malfunctioned and Windows does not recognise it.
This now happens all the time, and I have gone through the trouble shooter, and everything returns ok. There is no yellow exclamaton mark over the device, which is named unknown device. All my other USB devices work. In the device manager, it says that no drives are installed for the device.
i tried thewindows update, but t appeard i have all the available updates.
can you please help me, thhis is driving me mad.

Thank you! I was just searching for some help on this topic, and your suggestion helped me fix the problem. Thank you, thank you. I've learned a little something new, and you saved me lots of headache.

One note: my offending "unknown device" was listed under "Other Devices" within the Device Manager. Now it correctly shows "Palm OS Handheld Devices."
