Hi,
Ajays latest patches make MUSB behave a lot better on beagleboard, but
my DVB stick still errors when beginning to stream data (scanning
frequencies works):

Is this a problem with MUSB, omap dma or the dvb stack?

ISTR a similar problem discussed on Linux-USB in the last
few months ...
Don't recall the outcome for sure, but I think the problem
was the DVB stack passing a DMA-unsafe buffer to USB. If the
buffer came from vmalloc rather than kmalloc or get_pages,
passing it to USB is not allowed.

I'd say dvb stack. This small patch fixed my dvb-t stick with
a omap2 board:

Looks like a fair fix, at a quick look.
I'm kind of surprised that bug has been known for what
looks like about a year now, with a trivial fix that
hasn't yet been merged through the DVB tree ...
