Thanks for your patch. It does indeed load
"Freescale High-Speed USB SOC Device Controller driver (Apr 20, 2007)"
fine - but now when I want to use it:

modprobe g_ether
[   17.099363] g_ether gadget: using random self ethernet address
[   17.105316] g_ether gadget: using random host ethernet address
[   17.111974] usb0: MAC 1a:c7:9e:76:cc:45
[   17.115866] usb0: HOST MAC 66:a2:4a:0a:46:17
[   17.120199] g_ether gadget: Ethernet Gadget, version: Memorial Day 2008
[   17.126861] g_ether gadget: g_ether ready

these are "the last words": System hangs completely. Same behavior with
g_serial (these two I've tested).

Currently I can't investigate this further, not because of a bug - but a
flu.


Thanks,
