USB driver on µclinux to communucation with PC with USB

If you just want a serial 'console' port, there are 'cables' that convert 3.3v TTL rs232 data to USB (USB host one end, 6 pin 0.1" pitch the other). With an appropriate host (eg PC) driver the will give serial access via USB.

'Interestingly' linux may come with a driver (my one did), but windows may need one downloaded!
