Device not found #8

Closed brainstorm closed 3 years ago

@ericevenchick This is a followup on issue #3 , I'm not finding my cantact device with the python interface either: 

$ pip install cantact

(...all ok...)

$ ipython
Python 3.7.9 | packaged by conda-forge | (default, Dec  9 2020, 20:58:55)

In [1]: import cantact

In [2]: foo = cantact.Interface()

SystemError: DeviceNotFound

As mentioned on issue #3 , I'm testing cantact in a STM32F042G6 board since I bought the cantact-pro and I'd like to be familiar when it arrives.

Happy to debug/test it further for you, hints on what might be going on appreciated though ;)

Hmm, from #3 it looks like the wrong PID/VID... there have been a few out there. Can you confirm the PID/VID here using lsusb?

Fixed by using candlelight-cantact_fw instead of the "old" serial/ACM firmware in https://github.com/linklayer/cantact/issues/3#issuecomment-748440414, closing
