Here is a test case:
Two DVB-T USB adapters, dvb_usb_af9015 and dvb_usb_af9015. Different tuners,
Err, make it: dvb_usb_af9015 and dvb_usb_ce6230
Those both uses currently too small bulk urbs, only 512 bytes. I have
asked suitable bulk urb size for ~20mbit/sec usb2.0 stream, but no-one
have answered yet (search ml back week or two). I think will increase
those to the 8k to reduce load.
Nice, I'm ready to test if such change helps.
OK, I will make test version in couple of hours.
Does USB subsystem provide any way to monitor current raw USB data transfer rate?
I don't if there is tool for raw data analysis, but for DVB devices you
can use dvbtraffic tool.
