I´m not sure if the Sundtek driver are 'in tree' or 'out tree' because i'm not so deep in progging, for my understanding it is 'out tree'. For me the Sundtek device where a good choice wenn you have no PCIE slot available. The Support is extremely good, never seen such a good support. And the devices are working well!
Why do you need my HW IDs ore Diagnostics???? I'm fine, on my side everything is working well. It was just my thought that others may be interested in, because i've seen a lot of threads asking for help but didn't got it solved with that driver. But of course, if I can help, let's go!
