I seem to get this problem possibly more commonly at boot these days: usb 1-6: new full-speed USB device number 2 using xhci_hcd usb 1-6: device descriptor read/64, error -71 xhci_hcd 0000:00:14.0: Setup ERROR: setup context command for slot 1. usb 1-6: hub failed to enable device, error -22 usb 1-6: new full-speed USB device number 3 using xhci_hcd usb 1-6: device descriptor read/64, error -71 usb 1-6: hub failed to enable device, error -22 usb 1-6: new full-speed USB device number 4 using xhci_hcd usb 1-6: Device not responding to setup address. usb 1-6: Device not responding to setup address. usb 1-6: device not accepting address 4, error -71 usb 1-6: new full-speed USB device number 5 using xhci_hcd usb 1-6: Device not responding to setup address. usb 1-6: Device not responding to setup address. usb 1-6: device not accepting address 5, error -71 usb usb1-port6: unable to enumerate USB device and my keyboard doesn't work. I then unplug and re-plug it, and get usb 1-6: new full-speed USB device number 9 using xhci_hcd usb 1-6: New USB device found, idVendor=2516, idProduct=0020 usb 1-6: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-6: Product: Quickfire Rapid i usb 1-6: Manufacturer: CM Storm Any ideas? Some setup delay that isn't long enough at boot time for a slightly finicky device? It has happened before, but now I've gotten it twice within a couple of days: Nov 02 12:18:56 i7.lan kernel: usb 1-6: device descriptor read/64, error -71 Nov 28 16:54:06 i7.lan kernel: usb 1-6: device descriptor read/64, error -71 Nov 30 11:26:35 i7.lan kernel: usb 1-6: device descriptor read/64, error -71 (I've had this keyboard since mid-September, and looking at the logs this machine has been rebooted 41 times since, with those three failures..)
