You don't get me - I have *no* VirtualBox (or any proprietary) modules running - but I can reproduce this problem using *the same system running under* VirtualBox in Windows 7 64. It's almost definitely either a USB driver bug or video4linux driver bug: I'm CC'ing linux-media and linux-usb mailing lists, the problem is described here: https://lkml.org/lkml/2012/10/20/35 https://lkml.org/lkml/2012/10/20/148 Here are the last lines from my dmesg (with usbmon loaded): [ 292.164833] hub 1-0:1.0: state 7 ports 8 chg 0000 evt 0002 [ 292.168091] ehci_hcd 0000:00:1f.5: GetStatus port:1 status 00100a 0 ACK POWER sig=se0 PEC CSC [ 292.172063] hub 1-0:1.0: port 1, status 0100, change 0003, 12 Mb/s [ 292.174883] usb 1-1: USB disconnect, device number 2 [ 292.178045] usb 1-1: unregistering device [ 292.183539] usb 1-1: unregistering interface 1-1:1.0 [ 292.197034] usb 1-1: unregistering interface 1-1:1.1 [ 292.204317] usb 1-1: unregistering interface 1-1:1.2 [ 292.234519] usb 1-1: unregistering interface 1-1:1.3 [ 292.236175] usb 1-1: usb_disable_device nuking all URBs [ 292.364429] hub 1-0:1.0: debounce: port 1: total 100ms stable 100ms status 0x100 [ 294.364279] hub 1-0:1.0: hub_suspend [ 294.366045] usb usb1: bus auto-suspend, wakeup 1 [ 294.367375] ehci_hcd 0000:00:1f.5: suspend root hub [ 296.501084] usb usb1: usb wakeup-resume [ 296.508311] usb usb1: usb auto-resume [ 296.509833] ehci_hcd 0000:00:1f.5: resume root hub [ 296.560149] hub 1-0:1.0: hub_resume [ 296.562240] ehci_hcd 0000:00:1f.5: GetStatus port:1 status 001003 0 ACK POWER sig=se0 CSC CONNECT [ 296.566141] hub 1-0:1.0: port 1: status 0501 change 0001 [ 296.670413] hub 1-0:1.0: state 7 ports 8 chg 0002 evt 0000 [ 296.673222] hub 1-0:1.0: port 1, status 0501, change 0000, 480 Mb/s [ 297.311720] usb 1-1: new high-speed USB device number 3 using ehci_hcd [ 300.547237] usb 1-1: skipped 1 descriptor after configuration [ 300.549443] usb 1-1: skipped 4 descriptors after interface [ 300.552273] usb 1-1: skipped 2 descriptors after interface [ 300.556499] usb 1-1: skipped 1 descriptor after endpoint [ 300.559392] usb 1-1: skipped 2 descriptors after interface [ 300.560960] usb 1-1: skipped 1 descriptor after endpoint [ 300.562169] usb 1-1: skipped 2 descriptors after interface [ 300.563440] usb 1-1: skipped 1 descriptor after endpoint [ 300.564639] usb 1-1: skipped 2 descriptors after interface [ 300.565828] usb 1-1: skipped 2 descriptors after endpoint [ 300.567084] usb 1-1: skipped 9 descriptors after interface [ 300.569205] usb 1-1: skipped 1 descriptor after endpoint [ 300.570484] usb 1-1: skipped 53 descriptors after interface [ 300.595843] usb 1-1: default language 0x0409 [ 300.602503] usb 1-1: USB interface quirks for this device: 2 [ 300.605700] usb 1-1: udev 3, busnum 1, minor = 2 [ 300.606959] usb 1-1: New USB device found, idVendor=046d, idProduct=081d [ 300.610298] usb 1-1: New USB device strings: Mfr=0, Product=0, SerialNumber=1 [ 300.613742] usb 1-1: SerialNumber: 48C5D2B0 [ 300.617703] usb 1-1: usb_probe_device [ 300.620594] usb 1-1: configuration #1 chosen from 1 choice [ 300.639218] usb 1-1: adding 1-1:1.0 (config #1, interface 0) [ 300.640736] snd-usb-audio 1-1:1.0: usb_probe_interface [ 300.642307] snd-usb-audio 1-1:1.0: usb_probe_interface -
