I got this message when setting up my Grape 1.
"Opening device/dev/hidraw1
Not a valid GPS Clock Device: Success
Device Info:
vendor: 0x1dd2
product:0x2443

I've done the diagnostics on this brand new LB GPS, and it says it has latest firmware and is working correctly. Checked with VNA and it has good signal right at 10MHz. What now?

This means you most likely booted the RasPi with a keyboard / mouse plugged into it.

The LB GPSDO sneaks in as Human Interface Device (hidraw*) so to avoid yearly uSUX $600+ license fees.

Reboot the system without the kybd / mouse and you should be good to go.
