Hi Martin   they worked yesterday after executing the script I've sent. But today they're dead. I don't know why but dead is the only word I find.

Let me know if I should execute commands to isolate the problem: Thanks ----- michael@michael-ubuntu:~$ ls -l /dev/input total 0 drwxrw-rw-+ 2 root root    140 Aug  5 08:02 by-id drwxrw-rw-+ 2 root root    160 Aug  5 08:02 by-path crw-rw-rw-+ 1 root root 13, 64 Aug  5 08:02 event0 crw-rw-rw-+ 1 root root 13, 65 Aug  5 08:02 event1 crw-rw-rw-+ 1 root root 13, 74 Aug  5 08:02 event10 crw-rw-rw-+ 1 root root 13, 75 Aug  5 08:02 event11 crw-rw-rw-+ 1 root root 13, 76 Aug  5 08:02 event12 crw-rw-rw-+ 1 root root 13, 77 Aug  5 08:02 event13 crw-rw-rw-+ 1 root root 13, 78 Aug  5 08:02 event14 crw-rw-rw-+ 1 root root 13, 79 Aug  5 08:02 event15 crw-rw-rw-+ 1 root root 13, 80 Aug  5 08:02 event16 crw-rw-rw-+ 1 root root 13, 81 Aug  5 08:02 event17 crw-rw-rw-+ 1 root root 13, 82 Aug  5 08:02 event18 crw-rw-rw-+ 1 root root 13, 66 Aug  5 08:02 event2 crw-rw-rw-+ 1 root root 13, 67 Aug  5 08:02 event3 crw-rw-rw-+ 1 root root 13, 68 Aug  5 08:02 event4 crw-rw-rw-+ 1 root root 13, 69 Aug  5 08:02 event5 crw-rw-rw-+ 1 root root 13, 70 Aug  5 08:02 event6 crw-rw-rw-+ 1 root root 13, 71 Aug  5 08:02 event7 crw-rw-rw-+ 1 root root 13, 72 Aug  5 08:02 event8 crw-rw-rw-+ 1 root root 13, 73 Aug  5 08:02 event9 crw-r--r--+ 1 root root 13,  0 Aug  5 08:03 js0 crw-rw-rw-+ 1 root root 13,  1 Aug  5 08:02 js1 crw-rw-rw-+ 1 root root 13, 63 Aug  5 08:02 mice crw-rw-rw-+ 1 root root 13, 32 Aug  5 08:02 mouse0 michael@michael-ubuntu:~$ ls -l /dev/input/by-id ls: cannot access /dev/input/by-id/usb-CH_PRODUCTS_CH_FLIGHT_SIM_YOKE_USB-joystick: Permission denied ls: cannot access /dev/input/by-id/usb-CH_PRODUCTS_CH_FLIGHT_SIM_YOKE_USB-event-joystick: Permission denied ls: cannot access /dev/input/by-id/usb-Logitech_USB_Receiver-if01-mouse: Permission denied ls: cannot access /dev/input/by-id/usb-Logitech_USB_Receiver-if01-event-mouse: Permission denied ls: cannot access /dev/input/by-id/usb-Logitech_USB_Receiver-event-kbd: Permission denied total 0 l????????? ? ? ? ?            ? usb-CH_PRODUCTS_CH_FLIGHT_SIM_YOKE_USB-event-joystick l????????? ? ? ? ?            ? usb-CH_PRODUCTS_CH_FLIGHT_SIM_YOKE_USB-joystick l????????? ? ? ? ?            ? usb-Logitech_USB_Receiver-event-kbd l????????? ? ? ? ?            ? usb-Logitech_USB_Receiver-if01-event-mouse l????????? ? ? ? ?            ? usb-Logitech_USB_Receiver-if01-mouse michael@michael-ubuntu:~$ uname -a Linux michael-ubuntu 3.13.0-30-generic #55-Ubuntu SMP Fri Jul 4 21:40:53 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux michael@michael-ubuntu:~$ lsusb Bus 002 Device 002: ID 8087:8000 Intel Corp.
