I have several HP iPaq 210 Enterprise handhelds that are giving me a headache. Each one is on a Windows 7 32bit desktop. Sometimes every day the user will get a message that the USB device in not recognized. At this time the user will not be unable to sync to the desktop. If they press the reset button on the side of the handheld while in the docking station it will reboot and the desktop will recognize the handheld and the user can sync again. This will only last for several days or sometimes less than that. What is the problem with these devices? Is it a Windows 7 setting? Any help will be greatly appreciated.
