Have you enabled USB 2.0 on your host system? If yes -> causes issues
(Windows Bluescreen e.g.) with printers and sometimes other USB 2.0
devices. If you set it to USB 1.1, it should be fine but the transfer rate
is extremely low.
I would propose the ehci-patch from David, this works quite nice and gives
a good transfer performance and no bluescreens with printers and so on.
Best regards,
Erik
