cam Posted November 1, 2018 Posted November 1, 2018 Hi All, I am having issues reading frames from a usb camera connected to my nanopi neo air. I can get images from a logitech C170 webcam fine but not from this other USB camera module. I can access it from my mac/ubuntu VM fine so it definitely works. The device is recognised as a video device and mounts to /dev/video0 but times out when I try to get frames from it. It seems like a driver issue but I can't figure it out. Here is the dmesg output after I plug it in: [Nov 1 06:27] usb 8-1: USB disconnect, device number 6 [ +2.029724] usb 5-1: new high-speed USB device number 22 using ehci-platform [ +0.160076] usb 5-1: device descriptor read/64, error -71 [ +0.280002] usb 5-1: device descriptor read/64, error -71 [ +0.270029] usb 5-1: new high-speed USB device number 23 using ehci-platform [ +0.379982] usb 5-1: device descriptor read/64, error -71 [ +0.279977] usb 5-1: device descriptor read/64, error -71 [ +0.120166] usb usb5-port1: attempt power cycle [ +0.489866] usb 5-1: new high-speed USB device number 24 using ehci-platform [ +0.439988] usb 5-1: device not accepting address 24, error -71 [ +0.149994] usb 5-1: new high-speed USB device number 25 using ehci-platform [ +0.440043] usb 5-1: device not accepting address 25, error -71 [ +0.000245] usb usb5-port1: unable to enumerate USB device [ +0.479723] usb 8-1: new full-speed USB device number 7 using ohci-platform [ +0.263076] usb 8-1: not running at top speed; connect to a high speed hub [ +0.023017] usb 8-1: New USB device found, idVendor=0c45, idProduct=6366 [ +0.000036] usb 8-1: New USB device strings: Mfr=2, Product=1, SerialNumber=3 [ +0.000022] usb 8-1: Product: HD USB Camera [ +0.000023] usb 8-1: Manufacturer: HD USB Manufacturer [ +0.000022] usb 8-1: SerialNumber: SN0001 [ +0.008121] uvcvideo: Found UVC 1.00 device HD USB Camera (0c45:6366) [ +0.027655] uvcvideo 8-1:1.0: Entity type for entity Extension 4 was not initialized!
