Great review and nice little forum you have going here.
just wanted to give some hope to the Linux (and maybe Mac) users out there – I bought one of these readers today, plugged it into my Kubuntu PC and it identified and mounted the external disk straight away. I’m running a fully updated 9.10 64-bit version using kernel 22.214.171.124-19-generic. I’ve also updated the 511eb firmware.
It may be that this is specific to the 64-bit kernel – I’ll have a play with my 32-bit laptop when I have some time, but take heart, it works!
