Steve I don't know everything you've tried but I found this too.
Did you run ckdisk yet?
And sorry if this is just added aggravation.
With a new device driver installed, the majority of problems should be resolved. If not, however, you can reinstall the USB controllers, via Start > right-click Computer > Properties > Device Manager > Universal Serial Bus Controllers. Start with the USB Root Hub devices and reinstall the drivers by right-clicking and selecting Uninstall; once this is done, go to Action > Scan for hardware changes… to begin reinstallation.
One last thought – if new drivers don’t resolve the problems you’re facing, try the same device on a different computer; the problem might relate not to the hardware but to your USB cable. If you suspect this, find a good quality replacement cable.
