Support for Healson C30L

[hamzaMahdi]

Hey! Just wondering if there are any plans to support other Healson models such as the C30L. I am trying the package on MacOS and I get the following error:

probe = usbProbe.UP20()
Traceback (most recent call last):
File "", line 1, in
File "/Users/hamzamahdi/Desktop/lueder/pyusbus/pyusbus/acq.py", line 182, in init
dev = usb.core.find(idVendor=0x04B4, idProduct=0x8613)
File "/Users/hamzamahdi/Library/Python/3.9/lib/python/site-packages/usb/core.py", line 1309, in find
raise NoBackendError('No backend available')
usb.core.NoBackendError: No backend available

Thanks !
