I have an issue that inexplicably occurred with my Logitech USB Headset on Windows XP. It appears to connect and then I get an error "USB device not recognised". This message will repeat itself for so long as the USB device is plugged in until it is removed or it seems to 'turn itself off'. The little blue mute / unmute light stays on for a while and then it seems to turnitself off even when connected to the USB port
Strangely, every now and again Windows will recognise the headset, but then promptly 'unrecognises' it again. This is very odd and I am wondering who can provide me some pointers to assist in determining if it is the headset or not and why. Note that this seems to occur on a Vista machine and a different XP machine as well, so I am pretty sure it is the headset, but am at a loss to explain why it would be working one day and not the next.
