I have been using the SD card reader for a couple of months and it suddenly quick working. Same camera same SD card . I have a 32 gig wifi iPad one, running iOS 4.3 - files are on the card in folder labeled DCIM and are 8 character file names. I plug in the card reader and nothing happens. It was working flawlessly for months. When it stopped working I was running 4.2 - and then updated to 4.3 this week but it didn't help. Any ideas?
