Hi! First of all, thanks for your great work to make DSM available to us!
I have installed DSM 4.1 2668++ on Asrock AD2550-ITX http://www.asrock.com/mb/Intel/AD2550-ITX/index.asp (Dual core Atom, Intel NM10 Express, USB 3.0 with ASMedia ASM1042) and it works quite well, well with one exception though: USB.
I have disabled the USB 3.0 interface. On the USB 2.0, I added my HP printer and it is correctly recognized by the DSM in the list of the "External Devices". But no luck at all with USB drives: I have tried 2 card readers, 4 USB sticks, one WD drive - no luck at all. I have seen some other questions like this, but no answer at all.
Could you please give us a hint, whether we can fix it ourselves, or you plan to work at this?
Thanks a lot in advance!
