USB devices not getting recognised



I am having problems whereby usb devices are not being recognised. This is
the case for a wireless modem (never recognised), a usb memory stick (not
recognised about 3 in every 5 times I insert it) and my portable cd writer
(not recognised about once every 5 times I insert it into the usb drive).
Regardless of what usb drive I use, the results are the same. I am on XP SP2.

I have been unable to install the wireless modem - when the time comes for
me to insert the modem into the usb port, I get a popup saying "USB device
not recognised". It is shown as an "Unknown Device" in the Device Manager,
and when I go into the properties, it says that no drivers are installed for
this device. I tried using the Windows troubleshooting but to no avail. The
modem installs fine on any other machine I have tried it on. The problem is
intermittent with the memory stick and the cd writer - sometimes they are
recognised, sometimes they are not.

This would seem to be a problem with the USB drives on my pc. I have no idea
what might be the problem, and the intermittent nature of the problem makes
it even more confusing. Anyone got any ideas?

In the case of the wireless modem, have you installed the drivers before
connecting the device to the PC?
