Thanks for checking the tree so early.

Can't say much about this one, but I'd like you to only keep this one
reverted and sort out the regressions in the musb core first.

Which role does your musb-based hardware have in this case, and which
MUSB_* config symbols do you set? You should have USB_MUSB_GADGET.

Good catch, I didn't expect board files to depend on config symbols that
have no effect on the driver itself.

Please check the attached patch and let me know if it helps.


Thanks,
Daniel

I've posted a patch fixing the issue
http://comments.gmane.org/gmane.linux.usb.general/89541
There were some comments on it. I'll be posting a new version for it.

Thanks

hmm, n8x0 used tusb6010, so perhaps a similar patch needs to be cooked
for that too. Right now, let's to the minimum fix, which is just to
increment the array size to 3 and for v3.12 we do the changes that I
suggested.

I have USB_MUSB_DUAL_ROLE set. But also with USB_MUSB_GADGET the result
is the same.

The N900/RX-51 board file sets mode to MUSB_PERIPHERAL (see
mach-omap2/board-rx51.c).

This looks fine, however, I currently cannot test the host mode.

Here are full details:

Kernel v3.11-rc1 and the following USB fixes:
	ARM: omap2: fix musb usage for n8x0
	musb: omap: Fix: pass all the resources to musb core

When I boot N900 and load g_ether, I get the following logs:

On my workstation (stock Debian 3.9 kernel) I see the following:

I'm now running -rc2 with above fixes and reverts (the only way to get
USB working). I'm seeing an additional issue, the following crash happens
always on N900 when doing "poweroff":

Yes, with the mentioned patches reverted, musb_to_hcd() will return a
faulty pointer. You can't easily revert them unfortunately.

Your platform needs a real fix, I just have trouble understanding why a
removed usb_add_hcd() would make the gadget code fail.

Sorry for the trouble, but I don't currently have a board with musb in
gadget mode to reproduce this issue.

Thanks,
Daniel

If you have any ideas what to look for, I can maybe try to debug this
issue.

Below are some logs with additional DEBUGs enabled.

Please try changing the .mode field of musb_board_data to MUSB_OTG in
your board file (arch/arm/mach-omap2/board-rx51.c). That should bring
back the call to usb_add_hcd(), provided that you have USB_MUSB_DUAL_ROLE=y.

I still don't see a reason why this is should be necessary for
peripheral-only use though.
