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?
I have a dvb stick using similar drivers and I'm seeing similar
problems on omap3-musb, omap3-ehci and marvell-kirkwood-ehci, so I
suspect the dvb dudes broke arm.
regards,
Koen
