I am using 2008HE and used the linux flasher application to set --enable-rd-mode and --enable-usb-host-mode. I have tested with multiple USB card readers and cards, and they work perfectly, mounting /dev/sda or /dev/sda1. I hope to get external wifi adapters to work, but currently there is no rt73 drivers for the 770 kernel. I haven't yet tried an external hard-drive, but will later. The F-F adapter is also from dealextreme: http://www.dealextreme.com/details.dx/sku.2646 Here is an annotated pic of my setup:



The AA-battery powered device I bought from poundland (UK shop), so it's not branded. I think it is meant to charge phones and devices "on-the-go" as it came with multiple adapters including the USB one shown. I think they have similar devices on dealextreme. Pic here:
