Trying to get it to work under Darwin (Linux desktop computer) or Kylie (Linux netbook) was a mess of missing libraries, finding COM ports, and so on.
Tried it on a Mac. The Mac didn't even spot the board. That's a PPC Mac AND an Intel.
Hauled it over to Becket (WinXP desktop). Took a little arguing to get it to find the driver folder in the download file, but it finally did. Took three tries to find the right COM port.
It found it and uploads to the device perfectly.
