(davidgil-uk):
I'm on a Beagle-C4 board with a powered usb hub plugged into the OTG
port with a usb ethernet adapter.
It looks like MUSB was disabled by commit
61e9beafdd6f2b2d27ad5935a2de9c46709b9671
and I think this is the reason I can't use the ethernet I have plugged into the
OTG port.
grep -i musb /boot/config-2.6.38-1000-linaro-omap
# CONFIG_USB_MUSB_HDRC is not set
At boot I don't see any hub lights on (except the power LED); on 2.6.37-1002
(and earlier) I used to
be able to get the Hub to come on by doing a modprobe g_ether; my guess is that
kicked the port
into OTG host mode. That now says no such device when I modprobe g_ether.
The other recommended trick of writing to
/sys/devices/platform/musb_hdrc/mode doesn't help since that's missing.
