Answer: Card reader not being detected by the PC

I found this on SanDisk’s site and thought that I would paste it out here so that it might help many of you.  Go to the link below for more but that is the computer systems which it supports.  I can tell you that it also works on Windows 10.  Mine is currently connected to and running on win10.  I plugged it in, and had trouble. After a reboot or two things straightened out. It is reading all of the card drives.  I did look at device mngr, tried scanning for new hardware or hardware changes, etc and that did not help, unless doing that plus plugging it in with a card in it with the one or two reboots afterwards did the trick.  Hope it helps someone.
