- From what I can remember when I did my first test, this is because a
linux kernel module is still using the device.
So what you want to do, is try and tell the kernel to release the device:
if device.is_kernel_driver_active(interface):
try:
device.detach_kernel_driver(interface)
detached = True
except Exception as e:
print "ERROR: Could not detach device from kernel:", e
You could also try and make sure the kernel doesn't load a module for
the device, or use rmmod to remove the module associated with the device.
Kind regards
