Is anyone successfully using the file backed storage usb gadget?
I have it configured and working on the 2.6.36 kernel, (being mounted
by an xp machine...) But it only mounts every 2nd time I plug in the
The usb port on the gumstix is configured as "peripheral", not otg, if
that makes a difference.
When it doesn't work, I still see twl4030_usb saying "HW_CONDITIONS
0xd0/208; link 2", so it appears that it does see vbus correctly when
the usb cable is inserted. But turning on debug for musb, I don't see
any messages. I tried to capture a trace with usbmon, but when it
doesn't mount, there are no usb messages, so it isn't even trying.
How does the twl4030 seeing vbus cause musb_hdrc to get kicked off?
