Re: USB slave

[Simone Vellei <simone.vellei@xxxxxxxxxxxxxxxxxxx>]

Ok, I'm reading some specification and code of linux-2.4 usb-gadget 
support...I noticed that i must have a USB device controller (such as 
NetChip-2280 or Toshiba-TC86C001) connected to PCI bus.

http://www.linux-usb.org/gadget/

The "gadget-zero" driver (a skeleton for usb gadget development) depends 
from CONFIG_PCI...so I think that without a PCI bus (and related usb 
device controller) we can't develop a kernel driver for this device.

Simone
