My UVC cam is not working with the musb_otg driver and libusb(3) on the BeagleBone Black. With the following changes to the musb_otg.c, it feels like the transaction is performed as expected but the data doesn't pass to the libusb_transfer's buffer. Does anyone know what is wrong? 1729c1729 < MUSB2_WRITE_1(sc, MUSB2_REG_RXNAKLIMIT, MAX_NAK_TO); --- > MUSB2_WRITE_1(sc, MUSB2_REG_RXNAKLIMIT, 0); 4046c4046 < parm->hc_max_frame_size = 0x400; --- > parm->hc_max_frame_size = 0xc00; SAITOU Toshihide
