no backend avaliable

[ginghus-khan2000]

Hi, I appreciate the effort of creating the library. I have a problem (of course, sorry). I've installed
-Python 3.9.x
-Pip3
-ticlib
-usbpy

I try running your example code and get this error.

Traceback (most recent call last):
File "/Users/admin/Documents/Python Programming/tic test 2.py", line 1, in
from src.ticlib import TicUSB
ModuleNotFoundError: No module named 'src'

so I took out the src. and got

Traceback (most recent call last):
File "/Users/admin/Documents/Python Programming/tic test 2.py", line 4, in
tic = TicUSB()
File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/ticlib/ticlib.py", line 634, in init
self.usb = usb_core.find(**params)
File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/usb/core.py", line 1309, in find
raise NoBackendError('No backend available')
usb.core.NoBackendError: No backend available

I'm pretty much a noob to Python programming but trying. Can you suggest a solution? What am I doing wrong?

I got it working. Had to install HomeBrew and libusb. Works a treat. I just hate to think what I've done to my machine to install libusb (openUSB?). Thanks for the library. :)

Hi,
Did you end up using SRC still or removing SRC?

Also when you connect a device, are you able to disconnect? I can't seem to find the function to do that.

No, didn't use src.ticlib, just used "from ticlib Import TicUSB". I use IDLE, the Python interpreter built into to OS X. I haven't had any trouble with disconnecting a device. Just yank it out. Just check to see if connected using Pololu stepper controller software. The one thing I did have to change (in the Pololu software) was to disable the "enable timeout". Eric
