Candidate fix to eliminate need to remove usbhid module before using the capture tool

[Julian]

Hi,

The need on linux to "modprobe -r usbhid" if the device has a button is a bit inconvenient if you have a USB keyboard.... Fortunately there seems to be an easy work-around, which is to call libusb_set_auto_detach_kernel_driver() with the device handle.

See attached diff.

Although I've not tried it, I don't think that this will make any difference on MacOS, but shouldn't break anything as I check for the capability first.

Thanks,

Julian
