Hello guys,
I'm new to this mailing list, pyusb and Linux in general. So sorry, if some of
my questions may be a little stupid. I know my way around python, though.
Anyways, I got a raspberry pi with raspbian installed and I'm writing a python
script to read data from an air quality sensor that identifies itself as a HID
to the OS. When I try to read or write data to/from the device I get a USBError:
Could not claim interface 0: device or resource busy.
I think that happens because the os attaches a kernel driver to the device.
Correct?
In that case I found some code that tries to claim the interface:
if dev.is_kernel_driver_active (0):
dev.detach_kernel_driver(0)
usb.util.claim_interface (dev, 0)
But there I get a NotImplementedError. Why? Whats wrong and what can I do?
