Trouble reading data from USB device using Python

Question

I am using PyUSB library to read data from my USB mouse in windows. I was able to run the code in a UBUNTU virtual machine, but I can't replicate the same in windows. Can someone tell me what am I doing wrong? Following is the code and the error it throws :

import usb.core
import usb.util

# decimal vendor and product values
dev = usb.core.find(idVendor=1133, idProduct=49278)
if dev is None :
    raise ValueError('Device is not found')

print(dev)

# first endpoint
interface = 0
endpoint = dev[0][(0,0)][0]
# if the OS kernel already claimed the device, which is most likely true

if dev.is_kernel_driver_active(interface) is True:
  # tell the kernel to detach
  dev.detach_kernel_driver(interface)
  # claim the device
  usb.util.claim_interface(dev, interface)
collected = 0
attempts = 50
while collected < attempts :
    try:
        data = dev.read(endpoint.bEndpointAddress,endpoint.wMaxPacketSize)
        collected += 1
        print(data)
    except usb.core.USBError as e:
        data = None
        if e.args == ('Operation timed out',):
            continue
# release the device
usb.util.release_interface(dev, interface)
# reattach the device to the OS kernel
dev.attach_kernel_driver(interface)

Traceback (most recent call last):

Answer 1

The error says exactly what's wrong: You're using a function that makes no sense on your operating system (Windows).

So, don't do that? Either, if you know this is something only running on Windows, remove the check, or better, try:-handle the exception.

Answer 2

dev.is_kernel_driver_active(interface) is not supported in Windows
