Q: I have used my SD card reader with the lightning connector just fine until this awful OS 7 update! Now nothing works and all I get while trying to load pictures from my SD card to my iPad is that my device is not supported!

I'm having the same problem. very frustrating!!

Any answers out there?

Are the card readers apple ones or knockoffs? Unfortunately iOS7 brought with it software that looks for the authentication chip in  the cables and docks. If the manufacturer got permission from Apple to make devices then it should be fine, but if the manufacturer didn't get apple's permission then their chip isn't recognized, generating that error.

If your connectors are Apple ones have you tried to reset your device? Hold down the sleep and home keys for about 20 seconds or so until your iPad reboots. Then try again.

I am having the same issue and my adapter is an apple adapter (I used to like apple and was about to switch 100% not now) they really need to think about the customer not the bottom line after upgrading the new OS took over half my memmory they need to think about adding an SD slot on all devices to expand memmory not force you to purchase a new device APPLE YOU SUCK
