Squeak on a Raspberry Pi (RPi) is easy - download it on a PC then upload 3 files from there to the RPi, changes, sources, and image then run squeak [path]image. But a search for Squeak classes returned nothing for USB. So how do I communicate with a Webcam, microcontroller, or other peripheral?
A look at Pharo classes produced similar results. Also, couldn't get this Pharo to run on RPi. http://car.mines-douai.fr/category/software/pharos/

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.

Can’t help you there.

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 https://mail.google.com/mail/u/0/#search/pharo+rpi++slow/152d785715c67e37

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.
