on running fitbit.py, once the fitbit connects over ANT, i get this:

Traceback (most recent call last):
  File "python/fitbit.py", line 351, in <module>
    sys.exit(main())

and then on the next run:

  File "/home/brenda/projects/libfitbit/python/antprotocol/libusb.py", line 100, in _receive
    raise ANTReceiveException("Checksums for packet do not match received values!")
antprotocol.protocol.ANTReceiveException: Checksums for packet do not match received values!

which module named "usb" should i be using? Both the ones on pypi and the one packaged in ubuntu don't seem to work.

qdot commented 12 years ago

Yeah, we use pyusb 1.0a, you have to actually pull it off pyusb'd sourceforge site. I should update the readme with that.

Br3nda commented 12 years ago

sweet.. found it http://sourceforge.net/apps/trac/pyusb/

Even with a newer pyusb I get overflows on my laptop and netbook, but it works better on my media PC. All running Ubuntu 10.04 with the same pyusb (1.0.0-a0). Differences in USB controllers perhaps? If there's any information I can get which will help let me know.
