This model has major issues with SD cards, yes the drivers say 2006 and I also freaked and said to myself….what’s up with this…update…update.
If you look at the details this is the current driver for the latest windows update.
Others here have posted a “fix” that installs windows 8.1 drivers but it is BS and has caused users even more problems than they had before the “fix”
Teclast released an updated BIOS that was supposed to fix the issue for the A5C8 but that also created as many, or more, issues than it “fixed”
