Logic driver issue Windows

[the-lifting-engineer]

Running into a driver issue when I try to run the logic command on Windows 10.

gf logic -p /tmp/spi-capture12.sr
Sampling 8 channels at 17 MHz.
Press Ctrl+C to stop reading data from device.

ERROR: Communications failure -- check the connection to -- and state of -- the GreatFET.
(More debug information may be available if you run 'gf dmesg').
[Errno None] b'libusb0-dll:err [_usb_reap_async] timeout error\n'

Capture terminated -- waiting for data processing to complete.
Sigrok/PulseView compatible session file created: '/tmp/spi-capture12.sr'.
Sampled for 3.0159 seconds.

When I run dmesg it doesn't pull any errors and when I run the gf info command it has no problem detecting the board.

I've reinstalled the drivers through Zadig but it appears to have made no difference.

Can you please run gf info -a and put the output here? I'd also appreciate if you could run gf dmesg after an error occurs and also paste that output here.

gf info -a outputs: gf info -a
