[Voyage-linux] Alix 2d2, Voyage 0.8, AMD CS5536 USB UDC, USB Gadget Problem.

[Punky Tse]

According to http://cateee.net/lkddb/web-lkddb/USB_AMD5536UDC.html,

It seems it needs "CS5536 [Geode companion] UDC" PCI device in order to 
make ALIX as gadget.  lspci won't lie, if it can't be seen, you probably 
can't use it.

If you suspect a software problem, you can try different kernel (e.g. 
Debian squeeze kernel) to see.

Punky
