Hi,
I have been working with a Toradex Oak 4-20mA sensor. Using PYUSB I can
read from this device, but I would like to write to it such that I can
identify an individual sensor by flashing the LED or modifying its name. I
am running on Ubuntu 10.10 with Python 2.6.6 with PyUSB1.0
I believe the sensor has one normal endpoint plus the control endpoint???
I am using
dev.ctrl_transfer(0x40, 0x03, 0,0, 0x12)
I get a variety of errrors in response but primarily:
TypeError object is not iteratable - _interop.py Line 134
with slight modifications the following errors:
Unhandled AttributeError - module has no attribute backend libusb10.py
Line 408
Argument 4 TypeError wrongtype libusb10.py Line 548
Any help and guidance appreciated
regards
Eric Hewett
