Trying to connect to the ODrive board using odrivetool but getting “Task exception was never retrieved”. See full error message below.

I’m able to update the firmware on the board using odrivetool dfu since I’ve read some other forum posts suggesting that a firmware update might be necessary. However this did not solve the issue.

Maybe try updating odrivetool? We just pushed an update today. pip install --upgrade odrive - should report 0.6.2.post0

I am receiving the same error. I’ve tried this on a different laptop as well and I’m getting the same error.

I’ve fixed the issue with using WinUSB driver for Native Interface and using Windows cmd line instead of bash
