Hello,
I am using hardware that used the musb-ux500 USB driver. I am
wondering if there is a way to control
OTG state of this driver using
/sys/devices/platform/musb-ux500.0/musb-hdrc/mode files.
When I connect externally powered device I see that mode transitions
from b_peripheral to b_host. Whe

This patch adds a workaroud to solve Suspend/Resume issue that AX88772B turns
off its Ethernet PHY power in the case that REMOTE_WAKEUP feature doesn't
be set when system suspend. In this case, the PHY power will not be turned
on again when system resume, so the HW reset must be

The musb driver is usable in host, gadget or dual role mode depending
on the kernel configuration.
However, the musb gadget part of the driver is enabling OTG mode

Sure. And that behavior is documented. In any case, it's a bug for
drivers to depend on runtime suspend for carrying o
Hi Sarah,
Sorry for my delayed response, I just saw your e-mail (it got filtered
somehow). About your question: actually I'm not sure, I'll have to check that
to confirm it. I'll get back to you with an answer as soon as I have it.
Best Regards,
Alexis Cortes.

I will try my best to convince you then.
Hi!

module is loaded on Nokia N900. I do not know where is problem
and due to immediatelly kernel crash when loading driver I was
