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 ;)

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."

I'm having a similar, but unique, problem with my USB drives. If I use a USB device that requires a program interface (i.e., it's not a drag and drop device) then I have no problem getting my computer to recognize it. But if I use something like an SD memory card reader, that's when I run into a problem. However, my computer DOES recognize that the device is there. I get a popup notification in the system tray saying "found new device" and I have the button which allows me to "safely stop device." But if I go into "My Computer" and try to open the device to view the contents, it doesn't show up in the list of available drives.

I will try the fix described by n10city since it talks about "hidden devices", but thought someone might have another idea as well.

Thanks!

EDIT: I forgot to mention that I'm running Windows XP Home (SP2)

CJTucker,

What did u do to make the USB recognize the printer? I have a Color Laserjet 1500L printer and it's plugged into the USB port of the XP box however it's not printing anything. I use the USB device when adding printer(u know, lptr, serial, usb, etc). It did not come up with an error when I added that printer using the usb port but it's not printing at all. Suggestion?

Vincent

Hi everyone,

I tried using my palm to another computer but still have the same problem. I didn't try my scanner to another computer. I would like to ask for your help..thanks..
What should I do?

I saw the below view from http://support.microsoft.com/kb/871233
If your computer does not recognize the USB device, first try method 1 to work around this issue.
Back to the top
Method 1: Initiate recognition of the USB device by using Device Manager
To initiate recognition of the USB device by using Device Manager, follow these steps:

1. Click Start, click Run, type Devmgmt.msc, and then click OK. The Device Manager window opens.
2. Click to select your computer as the location for the scan.
3. On the Action menu, click Scan for hardware changes.

Windows XP recognizes the new device.
4. Close the Device Manager window.

If this method resolves the issue, you are finished.

If this method does not resolve the issue, go to method 2.
Back to the top
Method 2: 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.

Use this method if method 1 does not work. To disable power management of the USB hub, follow these steps:

1. Click Start, click Run, type Devmgmt.msc, and then click OK. The Device Manager window opens.
2. Expand Universal Serial Bus controllers.
3. Right-click a USB Root Hub in the list, and then click Properties. The USB Root Hub Properties dialog box is displayed.
4. Click the Power Management tab.
5. Click to clear the Allow the computer to turn off this device to save power check box, and then click OK.
6. Repeat steps 3 through 6 for each USB Root Hub in the list.
7. On the Action menu, click Scan for hardware changes.

Windows XP recognizes the new device.
8. Close the Device Manager window.

If this method does not resolve the issue, go to method 3.
Back to the top
Method 3: Restart the computer
To initiate recognition of the USB device, first unplug the USB device and restart the computer. Then, wait five to ten seconds before you plug the USB device into the computer or hub. Windows XP recognizes the new device.

If this method does not resolve the issue, you might want to review the articles in the "Similar Problems and Solutions" section, or contact Support. For information about how to contact Support, visit the following Microsoft Web site:

Hope can help you. Good luck!

I am having similar problems with my USB printer. It did work fine but now I get the message that Windows doesn't recognize the device. I checked Leo's Answers but couldn't find the file that should have an image of Win XP, as I don't have a CD. I'm not that confident with computers that I want to tinker around with it.
Is it possible that the USB problem could be connected to a power problem? The reason I ask, is that recently my computer wouldn't boot up completely and I discovered that it was related to too many devices attached to a power strip. I did have my electrical box upgraded a couple of years ago, but unfortunately, this is an old house with old wiring. My other printer works fine, whichever USB port it is connected to. Any advice will be appreciated.
