I am looking for a way to run 2 USB storage devices at once into my A500. I have a Toshiba USB hard drive that I have working without issue when I plug it into the USB port. The same thing for a SD card reader. What I want to do is plug both in at one time via a small USB hub I have and be able to transfer files directly between them. Right now it only seems to mount the first drive plugged in, and ignores the second. I am a photographer and want a way to back up my photos from the SD card over to the HD via my tablet. I am running ICS and do have it rooted. Any ideas of a app that will let me do this?
