A USB flash drive is a data storage device that is removable, rewritable, and small. A lot of people use USB flash drives for transporting and storing personal files and they may want to transfer these files to their iPad. Is this possible?
“The attached volume appears to be invalid”
“Accessory Unavailable: The attached accessory uses too much power”
“The attached USB device is not supported”
If you encounter these error messages, disconnect everything (The iPad Camera Connector and USB device) and then restart your iPad.
