If anyone has any objections, please let me know. =============== commit df36c5bede207f734e4750beb2b14fb892050280 upstream. Like other buggy models that had their fixes [1], the touchscreen with id 04f3:21b8 from ELAN Microelectronics needs the device-qualifier quirk. Otherwise, it fails to respond, blocks the boot for a random amount of time and pollutes dmesg with: [ 2887.373196] usb 1-5: new full-speed USB device number 41 using xhci_hcd [ 2889.502000] usb 1-5: unable to read config index 0 descriptor/start: -71 [ 2889.502005] usb 1-5: can't read configurations, error -71 [ 2889.654571] usb 1-5: new full-speed USB device number 42 using xhci_hcd [ 2891.783438] usb 1-5: unable to read config index 0 descriptor/start: -71 [ 2891.783443] usb 1-5: can't read configurations, error -71 [1]: See commits c68929f, 876af5d, d749947, a32c99e and dc703ec.
