I have no idea on vim, nano or getid (I cannot find them). This is more complicated than Einstein's theories..LOL --------------------------------------------------------- """First, it had nothing to do with fstab. This solution worked for me : Edit (as root) /etc/udev/rules.d/40-permissions.rules (I use vim, you can use nano, getid, or whatever) Change this line : SUBSYSTEM=="usb_device", MODE="0664" To : SUBSYSTEM=="usb_device", MODE="0666"""" -------------------------------------------------------- Failed to access the USB Subsystem                       CAN I GET HELP PLEASE!
