The main problem here is that I just cannot see how this could ever be correct: usb_fill_bulk_urb(pdx->PixelUrb[frameInfo][i], pdx->udev, epAddr, (dma_addr_t *) sg_dma_address(&pdx->sgl[frameInfo][i]), sg_dma_len(&pdx->sgl[frameInfo][i]), You cannot take a DMA address, cast it to a _pointer to_ a DMA address, and then regard it as a virtual address of the transfer buffer. However, finding the right virtual address was too hard for me, so I just stubbed it with NULL. At least usbmon won't oops then (it will not show any data but it's better than crashing). Also, too big a buffer was allocated elsewhere. And since we're at it, drop clearly unnecessary usb_buffer_alloc too, leaving it where it may be useful.
