Oddly, after a while it seems to have decided to stay on: [ 4021.819962] usb 2-7: Manufacturer: ELAN [ 4021.820163] usb 2-7: ep 0x2 - rounding interval to 64 microframes, ep desc says 80 microframes [ 4021.828338] input: ELAN Touchscreen as /devices/pci0000:00/0000:00:14.0/usb2/2-7/2-7:1.0/input/input221 [ 4021.828801] hid-multitouch 0003:04F3:016F.00D3: input,hiddev0,hidraw1: USB HID v1.10 Device [ELAN Touchscreen] on usb-0000:00:14.0-7/input0 [ 4023.903599] usb 2-7: USB disconnect, device number 86 [ 4024.198444] usb 2-7: new full-speed USB device number 87 using xhci_hcd [ 4024.211102] usb 2-7: New USB device found, idVendor=04f3, idProduct=016f [ 4024.211143] usb 2-7: New USB device strings: Mfr=4, Product=14, SerialNumber=0 [ 4024.211177] usb 2-7: Product: Touchscreen [ 4024.211197] usb 2-7: Manufacturer: ELAN [ 4024.211489] usb 2-7: ep 0x2 - rounding interval to 64 microframes, ep desc says 80 microframes [ 4024.219707] input: ELAN Touchscreen as /devices/pci0000:00/0000:00:14.0/usb2/2-7/2-7:1.0/input/input222 [ 4024.220555] hid-multitouch 0003:04F3:016F.00D4: input,hiddev0,hidraw1: USB HID v1.10 Device [ELAN Touchscreen] on usb-0000:00:14.0-7/input0 and it's been working since then. So, only after 87 cycles... Some kind of weird race condition? kevin
