Hello, I have a USB GPS receiver that I have not tested with OpenBSD. Only Debian on the pi 4. I use it to set my time also for amateur radio software. It's very important when you don't have internet in the woods trying to work digital models with a computer. I think they misunderstood what your talking about.
Sorry I can't be much help. I dug mine out and looked but it's not the same model. This is the one I've used on Debian. https://www.amazon.com/HiLetgo-G-Mouse-GLONASS-Receiver-Windows/dp/B01MTU9KTF/142-1215118-1037836 73 Reese On Fri, Oct 24, 2025 at 12:48:07PM +0200, Dorian B??ttner wrote: > mind sharing your dmesg to the list? > > On 10/24/25 08:11, [email protected] wrote: > > /bsd: uplcom0 at uhub1 port 1 configuration 1 interface 0 "Prolific > > Technology Inc.
