Re: [pyusb-users] Barcode Scanner

[John T. <jt...@gn...>]

In this case it is a hand scanner to test the code with as the second 
project is an operator will scan a bar code and auto load the G code 
file into the CNC software.

I've established communications with it and added a udev rule and added 
myself to the scanner group so I could talk to the scanner. And the 
results so far are:

$ python
Python 2.7.6 (default, Jun 22 2015, 18:00:18)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import usb.core
>>> dev = usb.core.find(idVendor=0x0c2e, idProduct=0x0901)
>>> dev.is_kernel_driver_active(0)
True
>>>
