It seems there is a bug in original firmware in Transcend TS-RDF8 card reader which prevents it from operating correctly when connected to a Linux machine over USB3.0 port. Please upgrade the firmware to latest version from Transcend webpage. I have just recently updated the version from TS08 (which was original in my reader) to TS17 and the device seems now to correctly operate with USB3.0 and linux kernel Linux version 3.6.11-1.fc16.x86_64 (yes, this is Fedora 16)
The updater need a MAC or Windows machine, I have used a Win7 laptop with USB2.0 port for updating the firmware. Also make sure the firmware of your USB3.0 controller is current - I have NEC/Renesas USB3 controller on ASUS Crosshair-IV Formula which also required firmware update. Before firmware update, I could force TS-RDF8 card reader to operate correctly (but slow!) when connected to linux machine over USB3.0 by setting appropriate /sys/block/sd?/device/max_sectors to a low value (default was 240, I needed to set is to 127 or less) Now after firmware update I can leave it at 240 or set to a maximum of 1024 and the card reader correctly reads and writes data.
