Picomotor controller model 8743-CL

[alexkish]

What can I try to modify in the code to make it work with the 2-axis controller model 8743-CL?

These are the commands that work and the responce to them:

Newport.get_usb_devices_number_picomotor()
1
print(comm_backend.PyUSBDeviceBackend.list_resources(idVendor=0x104d))
[(4173, 16384, 0)]

If I execute this command: stage1 = Newport.Picomotor8742(),
I get the following errors:
