Re: USB slave

[Simone Vellei <simone.vellei@xxxxxxxxxxxxxxxxxxx>]

May I use usbnet driver as usb device manager? Linux devices, such as 
Sharp Zaurus, and many others PDA (PXA2xx-based, etc.) use this driver 
to connect to another USB host.
Is there someone that can help me to try/develop this?

Thanks,
Simone
