Reader Eric writes in asking about the use of a USB mini hub with the Kingston MobileLite (a wifi sd card/usb drive reader). He is using a camera which uses compact flash memory cards, and would like to backup those cards to a portable hard drive. This was my exact same situation pior to a camera upgrade and sd cards. I used a portable hard drive/LCD/memory card reader from Sanho called the iPad Hard Drive. The LCD wasn't that great, but you could review photos (including RAWs) on it. It supported compact flash and sd cards. Plus you could used standard laptop hard drives. Backups were fast. It was great, and I still use it today, but was expensive ($300+) and big (about the size of a paperback) compared to wifi sd card readers available today. Using a usb mini hub with the new wifi sd card readers may be a cheap solution to backing up compact flash cards. Unfortunately both the apotop and MobileLite devices don't support multiple usb devices. You can only access one drive from the usb port. Luckily sanho also has a device called iUSBport which may be what we need. It supports multiple usb drives via a hub and is basically a wifi sd card reader with out the sd cards.
