I have an N and H as well, but I haven't tested them yet. Unfortunately, a colleague of mine tested positive for covid-19, which prompted several of us to get tests, and I received a positive test, so I cannot go back to the office for at least 5 days. (I am feeling fine today) Because I cannot go into the office I can't get the exact part number, but the card I have is a Patriot card, but a colleague of mine reported another brand was failing the same way. I was given permission to ship one out if you're interested but I have to wait until next week to test anything or ship anything. Please don't feel obligated to accept the card,but I know it can be easier to have actual hardware. > So much for a first response. I will have a closer look at your findings Thanks for responding. I'll try to get card info / part number from my colleague. adam > tomorrow. > > Thanks again, > > Wolfram >
