Solo Key (U2F/FIDO2) in Firefox?

I have a Solo V1 key and use it for 2FA on Gmail.

I installed libu2f-host and u2f-devd, added myself to u2f group, rebooted, and my USB key still doesn't work in Firefox (FreeBSD 14.1)

This and this seem to imply that it needs to be at uhid#? If so then that sounds similar to what I did for a joystick and FlightGear game (notes), but that would also have me wondering if there's a better way to go about that if some userspace apps expect things at uhid#?
 
A quick test through uhidd shows that something happens whenever I get to the 2FA part on Gmail with my key plugged in with uhidd attached to it (the block is repeated about 10 times):

Code: 
uhidd -d -h -k -m -o -v -s -H 'uhid' -u '/dev/ugen0.12'

ugen0.12[0]-> ugen0.12[0] vhid_task recevied:255 255 255 255 129 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

uhidd 2570 - - ugen0.12[0] libusb20_dev_request_sync failed
uhidd 2570 - - ugen0.12[0] libusb20_dev_request_sync failed
uhidd 2570 - - ugen0.12[0] libusb20_dev_request_sync failed
uhidd 2570 - - ugen0.12[0] libusb20_dev_request_sync failed

So it seems like Firefox sees and tries to communicate with my key, but it doesn't function (light LED doesn't change color; Firefox registers nothing with button press), and uhidd implies something further isn't working correctly
 
To me this looks like your key was not in the u2f-devd configuration.
What is the associated vendor and product ID ?

For hidraw (so the sysctl workaround), we will need firefox to update its code to use hidraw device on FreeBSD instead of only relying on uhid.
