USB Device no longer recognized

[Guest]

I have a usb label printer that functioned properly for almost a year. It is
now no longer recognzed by Windows. When I plug it into a USB port on the
computer (I have tried several of them), I no longer get the hardware found
notification sound, the device is no longer shown in Device Manager and is
not in the safely remove hardware listing in the task bar. All of my other
USB devices are working fine. As I said, I have tried different ports,
different USB cables with no success. I also plugged the device into my
laptop and it works properly. What to do?

Sounds like too many usb devices for the available power.
USB device does not function after connecting device to a Windows XP Service
Pack 2-based computer or to a Windows XP Tablet PC Edition 2005-based

I read the link you sent, however that can't be it. The device is pwered from
a separate power supply. I actually have no un-powered USB devices at all.
