Not sure about space parity. Every scanner we've used is programmable by barcode though. Not had any issues on Linux or Winows.

This is not a debate on whether or not the designers of the device could have chosen something else: clearly they should have.  The question is whether our vms should be able to communicate with it, and they should where possible.
