I have a Palm Zire 72s that I use at several different locations. My company uses the Zire 72 as a sales tool. So, we can HotSync at several different locations and at home.

1. My Palm HotSyncs at home and location #2.
2. Neither my Palm nor anyone else's will HotSync at location #1. We get "USB Device Not Recognized" error when plugging any USB cable attached to the Palm into any of the various USB ports on the front or back of the PC. I have used numerous cables to see if that might be the issue but these same cables work fine at location #1 and at home.
3. Other USB devices work fine on location #1's PC.
4. Location #1's PC is XP Home SP2. I recently reinstalled SP2 to see if this might fix the problem.
5. I have uninstalled Palm Desktop and reinstalled it numerous times. I even manually deleted all of the palm files and drivers left behind after the uninstall. I also used Palm's USBRegClean.exe after all of the uninstalls. I have tried installing Palm Desktop 4.1.4e as well as the version on the disk that shipped with the Palm Zire 72.
5. I have deleted all the USB Controllers from the XP Device Manager and then rebooted to have these reinstalled automatically. I tried "updating" the driver for the USB "Unknown Device" but no driver would be recognized as relevant and would not install.
6. I manually deleted virtually every reference to Palm in the registry. I did this after several hours of trying to fix this problem. I'm pretty familiar with the registry and did not delete anything that appeared even remotely valuable. This PC works fine for everything but this USB issue.

Any advice as to how else this problem might be fixed? Aside from buying a new PC, new USB card, or reinstalling Windows?

Thanks

Shacky, I'm having the exact same problem with my Palm T|X. Have you found a solution? Thanks!

Licking worked for me!
Lick the connections on the phone and at the end of the USB cable!
Worked like a charm after I had already rebooted windows XP, soft reset (pulled battery) the treo 650...then licked - BAM!
Good luck!

I did soft reset on Palm, it worked;

Sometimes I see the same problem with my Treo650 cradle. If I hold the connector firmly in the device, it makes the connection good. You might try cleaning the contacts with a q-tip and rubbing alcohol to make sure they're clean.

Im having the same problem with my Treo 650.. using the USB cable to sync.. I was able to sync on saturday.. had to wipe my phone.. now i can't sync.

i don't think it is USB.. or the cable.
i can use other devices in the USB..
when i plug in the cable i hear the phone connect but the machine doesn't show connection through explorer, system tray or device manager...

i have cleaned the connectors..tried different usb ports.

Please help i have an empty phone and all my data on my machine..

ihve wiped my phone several times now following the palm instructions!!

thanks in advance

Hi, this worked for me.
Disconnect the palm
Uninstall palm sofware
Reboot XP
Connect the palm cable
Now xp will recognize the palm.
Install palm software.
And hotsync
Hope it will help
