[Bug 608312] [NEW] Usb host mode on OTG doesn't work on Maverick with BeagleBoard

[Ricardo Salveti]

Public bug reported:

When booting Maverick on a C4 BeagleBoard the host mode on USB OTG
doesn't work as it should.

In theory it should just work when I add a micro usb cable (otg
compatible) connected to a powered hub.

Checking the device status:
Before plugging the cable:
ubuntu at beagle-maverick:/sys/devices/platform/musb_hdrc$ cat mode
b_idle

After plugging the cable:
ubuntu at beagle-maverick:/sys/devices/platform/musb_hdrc$ cat mode
a_idle

When it works it should just display "host" when you have the cable
connected, just like it worked on Lucid.
