The camera times out when the driver tries to get the current value of the UVC probe control. I would suspect a bug in the camera firmware that makes it crash when it received the previous GET_DEF(PROBE) request. GET_DEF(PROBE) can be skipped entirely by setting the UVC_QUIRK_PROBE_DEF quirk. Amila, could you please try that ? The easiest way to do so is to disconnect the camera, set the quirk with echo 0x100 > /sys/module/uvcvideo/parameters/quirks (running as root, or with sudo) and reconnect the camera. > Have you tried other UVC cameras on this system? > Are you able to try a later kernel version just to be sure? > > > > [ +0.000007] uvcvideo: Failed to initialize the device (-5). > > [ +25.599651] usbhid 2-1:1.2: can't add hid device: -110 > > [ +0.000031] usbhid: probe of 2-1:1.2 failed with error -110 > > > > > > "lsusb -d 4e45:5501 -v" output: > > > > Bus 002 Device 006: ID 4e45:5501 > > Device Descriptor: > > bLength 18 > > bDescriptorType 1 > > bcdUSB 3.00 > > bDeviceClass 239 Miscellaneous Device > > bDeviceSubClass 2 ? > > bDeviceProtocol 1 Interface Association > > bMaxPacketSize0 9 > > idVendor 0x4e45 > > idProduct 0x5501 > > bcdDevice 1.03 > > iManufacturer 1 (error) > > iProduct 2 (error) > > These (error)s might be a bit of a concern... > > > iSerial 0 > > bNumConfigurations 1 > > Configuration Descriptor: > > bLength 9 > > bDescriptorType 2 > > wTotalLength 249 > > bNumInterfaces 3 > > bConfigurationValue 1 > > iConfiguration 3 (error) > > bmAttributes 0x80 > > (Bus Powered) > > MaxPower 100mA > > Interface Association: > > bLength 8 > > bDescriptorType 11 > > bFirstInterface 0 > > bInterfaceCount 2 > > bFunctionClass 14 Video > > bFunctionSubClass 3 Video Interface Collection > > bFunctionProtocol 0 > > iFunction 0 > > Interface Descriptor: > > bLength 9 > > bDescriptorType 4 > > bInterfaceNumber 0 > > bAlternateSetting 0 > > bNumEndpoints 1 > > bInterfaceClass 14 Video > > bInterfaceSubClass 1 Video Control > > bInterfaceProtocol 0 > > iInterface 0 > > VideoControl Interface Descriptor: > > bLength 13 > > bDescriptorType 36 > > bDescriptorSubtype 1 (HEADER) > > bcdUVC 1.10 > > wTotalLength 81 > > dwClockFrequency 48.000000MHz > > bInCollection 1 > > baInterfaceNr( 0) 1 > > VideoControl Interface Descriptor: > > bLength 18 > > bDescriptorType 36 > > bDescriptorSubtype 2 (INPUT_TERMINAL) > > bTerminalID 1 > > wTerminalType 0x0201 Camera Sensor > > bAssocTerminal 0 > > iTerminal 0 > > wObjectiveFocalLengthMin 0 > > wObjectiveFocalLengthMax 0 > > wOcularFocalLength 0 > > bControlSize 3 > > bmControls 0x00000000 > > VideoControl Interface Descriptor: > > bLength 13 > > bDescriptorType 36 > > bDescriptorSubtype 5 (PROCESSING_UNIT) > > bUnitID 2 > > bSourceID 1 > > wMaxMultiplier 16384 > > bControlSize 3 > > bmControls 0x0000105f > > Brightness > > Contrast > > Hue > > Saturation > > Sharpness > > White Balance Temperature > > White Balance Temperature, Auto > > iProcessing 0 > > bmVideoStandards 0x 0 > > VideoControl Interface Descriptor: > > bLength 28 > > bDescriptorType 36 > > bDescriptorSubtype 6 (EXTENSION_UNIT) > > bUnitID 3 > > guidExtensionCode {ffffffff-ffff-ffff-ffff-ffffffffffff} > > Hrm ... Laurent - is that suspicious? or ok? An extension unit with no controls and a GUID set to all 1s. Sloppy firmware, really :-) It shouldn't cause any issue, but it shows the level of quality to expect from the device. Ideally these issues should be reported to the device manufacturer, but that's pretty hard to do in practice. > > bNumControl 0 > > bNrPins 1 > > baSourceID( 0) 2 > > bControlSize 3 > > bmControls( 0) 0x00 > > bmControls( 1) 0x00 > > bmControls( 2) 0x00 > > iExtension 0 > > VideoControl Interface Descriptor: > > bLength 9 > > bDescriptorType 36 > > bDescriptorSubtype 3 (OUTPUT_TERMINAL) > > bTerminalID 4 > > wTerminalType 0x0101 USB Streaming > > bAssocTerminal 0 > > bSourceID 3 > > iTerminal 0 > > Endpoint Descriptor: > > bLength 7 > > bDescriptorType 5 > > bEndpointAddress 0x82 EP 2 IN > > bmAttributes 3 > > Transfer Type Interrupt > > Synch Type None > > Usage Type Data > > wMaxPacketSize 0x0040 1x 64 bytes > > bInterval 1 > > bMaxBurst 0 > > Interface Descriptor: > > bLength 9 > > bDescriptorType 4 > > bInterfaceNumber 1 > > bAlternateSetting 0 > > bNumEndpoints 1 > > bInterfaceClass 14 Video > > bInterfaceSubClass 2 Video Streaming > > bInterfaceProtocol 0 > > iInterface 0 > > VideoStreaming Interface Descriptor: > > bLength 14 > > bDescriptorType 36 > > bDescriptorSubtype 1 (INPUT_HEADER) > > bNumFormats 1 > > wTotalLength 71 > > bEndPointAddress 131 > > bmInfo 0 > > bTerminalLink 4 > > bStillCaptureMethod 1 > > bTriggerSupport 0 > > bTriggerUsage 0 > > bControlSize 1 > > bmaControls( 0) 27 > > VideoStreaming Interface Descriptor: > > bLength 27 > > bDescriptorType 36 > > bDescriptorSubtype 4 (FORMAT_UNCOMPRESSED) > > bFormatIndex 1 > > bNumFrameDescriptors 1 > > guidFormat {55595659-0000-1000-8000-00aa00389b71} > > bBitsPerPixel 16 > > bDefaultFrameIndex 1 > > bAspectRatioX 0 > > bAspectRatioY 0 > > bmInterlaceFlags 0x00 > > Interlaced stream or variable: No > > Fields per frame: 2 fields > > Field 1 first: No > > Field pattern: Field 1 only > > bCopyProtect 0 > > VideoStreaming Interface Descriptor: > > bLength 30 > > bDescriptorType 36 > > bDescriptorSubtype 5 (FRAME_UNCOMPRESSED) > > bFrameIndex 1 > > bmCapabilities 0x03 > > Still image supported > > Fixed frame-rate > > wWidth 1920 > > wHeight 1080 > > dwMinBitRate 995328000 > > dwMaxBitRate 995328000 > > dwMaxVideoFrameBufferSize 4147200 > > dwDefaultFrameInterval 333333 > > bFrameIntervalType 1 > > dwFrameInterval( 0) 333333 > > Endpoint Descriptor: > > bLength 7 > > bDescriptorType 5 > > bEndpointAddress 0x83 EP 3 IN > > bmAttributes 2 > > Transfer Type Bulk > > Synch Type None > > Usage Type Data > > wMaxPacketSize 0x0400 1x 1024 bytes > > bInterval 0 > > bMaxBurst 15 > > Interface Descriptor: > > bLength 9 > > bDescriptorType 4 > > bInterfaceNumber 2 > > bAlternateSetting 0 > > bNumEndpoints 1 > > bInterfaceClass 3 Human Interface Device > > bInterfaceSubClass 0 No Subclass > > bInterfaceProtocol 0 None > > iInterface 0 > > HID Device Descriptor: > > bLength 9 > > bDescriptorType 33 > > bcdHID 1.11 > > bCountryCode 0 Not supported > > bNumDescriptors 1 > > bDescriptorType 34 Report > > wDescriptorLength 29 > > Warning: incomplete report descriptor > > Report Descriptor: (length is 7) > > Item(Main ): (null), data=none > > Item(Main ): (null), data=none > > Item(Main ): (null), data=none > > Item(Main ): (null), data=none > > Item(Main ): (null), data=none > > Item(Main ): (null), data=none > > Item(Main ): (null), data=none > > Endpoint Descriptor: > > bLength 7 > > bDescriptorType 5 > > bEndpointAddress 0x81 EP 1 IN > > bmAttributes 3 > > Transfer Type Interrupt > > Synch Type None > > Usage Type Data > > wMaxPacketSize 0x0040 1x 64 bytes > > bInterval 10 > > bMaxBurst 0 > > Device Status: 0x77e8 > > (Bus Powered) > > U2 Enabled > > Debug Mode > > > > > > I would appreciate any pointers to see if I can get this working. -- Regards, Laurent Pinchart
