Hello all, Glad the site certificate got updated. I was concerned. Anyway, I have used a Sony XQD USB adapter since 2018 when I got my nikon D850. Never a problem using it to transfer images to my computer. When I got back from atrip in early September, I found that the computer does not even acknowledge my plugging it into the USB port. Nothing. Looking into the File Manager, the device does not show up. Being a pack rat, I bought two back in 2018 so got the new, unused one. Same behavior, not acknowledged at all. Anyone else seen this? Maybe a Windows update altered XQD card reader recognition? I can buy a new card reader, but it seems silly. Thx.
