It can be even easier; just download the Squeak 5.0 All-in-One and run it.

All I know suggests that usb things are generally mapped as serial ports under *nix. You open serial ports and do whatever demented and weird, nay, dangerous, things *nix demands of you.

The place to ask pharo questions is
http://lists.pharo.org/mailman/listinfo/pharo-users_lists.pharo.org
btw, apparently Pharo UI runs slower than Squeak UI on RPi

Hi,

A friend and I are working on an interface for VA Smalltalk [1][2] to LibUSB [3].  When we
finish we intend to port our interface to Squeak/Pharo.  In the mean time maybe you can use a
few FFI calls to just enough of LibUSB to talk to a USB device.
