during searching for solution to problem with Beaglebone Black USB
unreliable reconnections, which i had, when i tried to reconnect devices

which restarts musb after babble interrupt,

To be honest, I don't exactly know, why that situation happens on SoC
and if is it hardware related, but it was working well for me and solved
that omnipresent issue.
Patch isn't applied to current kernels and i believe it will be very
helpful to either use it or provide similar mechanism for recovery.
The most appropriate way to get this merged is probably to just resend
the patch. Use git send-email so the patch authorship is properly taken
care for, and make sure to take the musb maintainer in Cc:.

Thank you for advice,
before doing that, i actually found, that maintainer Mr. Balbi was at
initial conversation about patch and had comments about introduction of
new specific things in recovery process instead of usage of all possible
generic things. It wasn't modified then. So that is the reason, why it
wasn't accepted.
I hope, it won't be too inappropriate to rather wakeup conversation
about that by CCing both. Because i think, mechanism is really usable
and quite a few BBB users, who had issues with reconnection according to
several discussions, also appreciate it.
Best regards,
Michal
