Hi, 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 2.2.6.31-19-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!
