I tried this app in my Xperia Pro (stock everything, 2.34, rooted) and it worked nicely, except for this:
mkdir failed for -p, Read-only file system
No such file or directory
I had to manually make the folders I had set in the app to be able to mount anything but, after that, mounting my devices was fine.
Also, the "please wait" message stays there for a long time, but as soon as text appears behind the "please wait" message, if I change the screen orientation, the message disappears and I can use the app.
Finally, my phone detects a couple card readers I have but, I cannot mount them, that is until I connect one (any) USB hub, after that I can mount my card readers.

root is needed or not? in few days I will try flash CM7 or CM9 and then I will try it again
Yes it is, I just did it. To use a hard drive, I had to use external power though. Also, have in mind the card reader issue I mentioned.
