you read the same DEVCTL register over and over again. Read it
once and only change the bits you want to change:

val); val |= MUSB_DEVCTL_SESSION; musb_writew(musb->mregs,
MUSB_DEVCTL, val);
btw, why do you disable and right after reenable session bit ?
A little comment would make things clearer, is that really necessary ?
It's really necessary,or if musb is in host mode,then it can't detect
the B-plug
If it's connected to PC.
ok, still you didn't fix the several reads of DEVCTL in a row.
could you provide a new version of the patch ?
