Upload script doesn't work with pyusb 1.0.0a3 #13

ghulands commented 2013年02月05日 01:13:36 +01:00 (Migrated from github.com)

Hi,
When installing with $ easy_install pyusb, 1.0.0a3 gets installed. When running the firmware updater, it complains because of missing functions in pyusb.

I would be great if you can update the script to support the latest, or can you let me know which version the script was coded against so I can upload the latest firmware.

Thanks,
Greg

It's working for me with 1.0.0a3 on Linux. Other OSX users have reported different problems. I'll try to get my hands on a Mac to experiment.

"No backend available" means pyusb can't find libusb. Make sure you have libusb installed.
