My USB modem is not recognised in WindowsXP. The USB port works as I have tried a printer in the same port, and the modem works as I have tried this on another PC. The only difference is that the modem is powered by USB whereas the printer has itsown power source. I have tried disconnecting devices to see if the system has low power but I have a 300W power supply so it should be ok.
Does anyone have any suggestions - is my mobo faulty? I am thinking of getting a PCI USB card to reslove this.

A cheaper and eaiser solution would be to get a powered hub, I had a Creative webcam the drew power from the usb port and on Athalon mobos it need a powered hub to work properly. Hope this helps.

Hi yes there is a problem with the current taken by USB devices on certain Mobo's ie in the UK the BT ADSL modem willnot work with certain ABIT mobos and as previous answer either a pci USB card or powered USB hub is required.

Hope this helps

Make sure that your modem is on the list of supported devices for XP.

XP may be refusing to recognize the modem because it is not supported.

Also, some USB devices need the drivers installed before you connect the device to the port.
