Can someone recommend a USB network adaptor that they have gotten to work with the Gumstix? and which USB network adaptor driver ( from menuconfig's Device Drivers-->USB support-->USB Network Adapters) to use with it.

Subject: Re: [Gumstix-users] USB network adaptor - /proc/bus/usb not mounted What is the manufacturer and model number of the ethernet device? =20 (not USB numbers, the product model number on the outside of the =20 case). Try doing a google search to see if anyone's ever used it =20 successfully with linux before.
