Reboot failure channel broken exception

1

When I try to reboot I get this error.
it’s kill me that I can’t reboot the boards. Any help would be appreciated.

ChannelBrokenException Traceback (most recent call last)

That always happens when rebooting. Looks like it’s working correctly :slight_smile:

Running 0.5.3 now and experience similar but not exact error. Error code I encounter was as below,

Exception in callback <CFunctionType object at 0x000001EF834FFA00>(<ctypes.winty…001EF833106C0>)
handle: <Handle <CFunctionType object at 0x000001EF834FFA00>(<ctypes.winty…001EF833106C0>)>

b’\x1b[91;1m23:24:27.270051400 [USB] Transfer on EP 0x03 still in progress. This is gonna be messy.\x1b[0m\n’

This happen randomly while I repeatably connect then reboot. After this error occur, i will have to restart the program in order for it to work again.

Any suggestion to prevent this?

That looks like a problem in the Windows libusb driver… (userspace/python usb driver support in windows is notoriously terrible)
See OSError with wxPython · Issue #203 · pyusb/pyusb · GitHub
Try reinstalling/updating python-usb and libusb. Or use a raspberry pi to access the ODrive.
