Subject: OMAP3430: MUSB host and hot-plugging
Date: Wed, 19 Mar 2008 17:14:41 -0700	[thread overview]
Message-ID: <87d4pqqmj2.fsf@paris.hilman.org> (raw)

Using the default config omap_3430sdp_defconig, I'm doing some basic
hot-plug tests of MUSB in host mode.

I noticed that after booting, the first time I connect my USB key, it
is detected just fine, the usb/scsi storage modulesare loaded by
hotplug and I can access the device just fine.

I then remove the key, and the kernel seems to detect the removal just
fine, and does what seems to be a clean shutdown.

However, if I then plug the key back in, nothing happens.  

Forcing a session start via "echo 'F' > /proc/driver/musb_hdrc" causes
the device to be (re)detected and things look good again.  It is not
until I force the session start that I see the interrupt and the
CONNECT event.

Any ideas why this isn't detected on insertion?

Thanks,

Kevin
