Hi Ricardo, I have a 4035:4035 and compiled the patched module today. As I didn't see any update on the patchwork, I suppose no logs were brought to you and therefore thought I could contribute. Here is the dmesg output: `[13784.543780] usb 3-6: uvc_v4l2_open [13784.546197] usb 3-6: uvc_v4l2_mmap [13784.546384] usb 3-6: uvc_v4l2_mmap [13784.546497] usb 3-6: uvc_v4l2_mmap [13784.546583] usb 3-6: uvc_v4l2_mmap [13784.546668] usb 3-6: uvc_v4l2_mmap [13784.546762] usb 3-6: uvc_v4l2_mmap [13784.546853] usb 3-6: uvc_v4l2_mmap [13784.546943] usb 3-6: uvc_v4l2_mmap [13784.554953] usb 3-6: Device requested 3060 B/frame bandwidth [13784.554965] usb 3-6: Selecting alternate setting 11 (3060 B/frame bandwidth) [13784.555469] usb 3-6: Allocated 5 URB buffers of 32x3060 bytes each [13785.143551] usb 3-6: Frame complete (EOF found) [13785.143556] usb 3-6: EOF in empty payload [13785.143558] usb 3-6: frame 1 stats: 3967/694/4677 packets, 1/3966/4677 pts (early initial), 4676/4677 scr, last pts/stc/sof 2481712061/2486485544/459 [13785.143735] usb 3-6: uvc_v4l2_poll [13785.243551] usb 3-6: Frame complete (EOF found) [13785.243557] usb 3-6: frame 2 stats: 88/695/798 packets, 1/87/798 pts (early initial), 797/798 scr, last pts/stc/sof 2486500781/2491273546/559 [13785.243749] usb 3-6: uvc_v4l2_poll [13785.343633] usb 3-6: Frame complete (EOF found) [13785.343648] usb 3-6: frame 3 stats: 88/694/798 packets, 1/87/798 pts (early initial), 797/798 scr, last pts/stc/sof 2491289501/2496061546/658 [13785.343851] usb 3-6: uvc_v4l2_poll [13785.344131] usb 3-6: uvc_v4l2_poll [13785.345209] usb 3-6: uvc_v4l2_poll [13785.345752] usb 3-6: uvc_v4l2_poll [13785.346174] usb 3-6: uvc_v4l2_release` And the yavta output: `Device /dev/video0 opened: ACER HD User Facing: ACER HD Us (usb-0000:00:14.0-6).
