[Bug] alias "mount-usb" only works with correct device /dev/sdb

[MRocholl]

usb-mount will try to mount device fount ad /dev/sdb1 even if the computer has a different layout for its usb-plugs.
Proposed solution:
Make alias dependend on device variable to be set at top of alias file.
Set up script should make this a prompt or include logic to automatically identify the right device

[MFreidank]

I second the notion that the set up script should handle this.
There should be an attempt to detect the desired USB device and a prompt to confirm the detected device or propose a different one.
Come to think of it: this should probably allow for a list of devices, as frequently people have more than a single usb plug available.
