If so, it is not clear to me how they should be aligned when the time

In both cases (with or without HCD_BH), usb_hcd_giveback_urb is called
every 0.01 sec. It is not clear why behavior is so different.

I've just measured that
it takes 150 us in average for pwc_isoc_handler to run
350 us - __usb_hcd_giveback_urb
So, it takes either 50 us (with HCD_BH) or 400 us (without) for
usb_hcd_giveback_urb to run.

On the power input jack, there is 4.8V. I found no voltage regulators

Many thanks for the hint. Am I right that we can not have multiple

Why dma_controller_create can not be set in struct musb_platform_ops?
Then each module would be able to set dma_controller_create it wants
