Hello, While doing some experiments with the stk1160 driver (for "Easycap" TV video capture devices), ran into problems using v3.13-rc4. The problem is that the stk1160 IRQ handler receives no URBs at all. When configuring with CONFIG_MUSB_PIO_ONLY this looks solved, but the bandwidth requirements are too large for PIO (it's a raw video device) and the video can't get captured. Interesting enough, using an old backported for v3.2 stk1160 driver, this same setup works with TI PSP v3.2 kernel. So, I guess it's some software bug in either the cppi41 dmaengine or the musb. I tried to compare the PSP to the mainline drivers but they seems *very* different and really beyond my understanding. Any ideas on how can I help debugging this?
