Title:
  musb config'd out on 2.6.38-1000 kernel

Status in Linaro Ubuntu Evaluation Builds:
  Fix Released
Status in Linaro Linux:
  Invalid
Status in “linux-linaro-omap” package in Ubuntu:
  In Progress

Bug description:
  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.
