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, -- Christoph
