No answer for ten days.
I have the same issue. The Samsung Galaxy S2 with the latest two ICS builds (the "official" release as well as the leaked one previous to that) seem to not work with my high-speed hardware, now (the early February release DID work). Flash drives and such work so I know the port is, physically, OK.
This is an important test. Can it be done? Somewhere the system needs to know and I would hope report if the port is in full- or high-speed mode.
And if anyone from Samsung is listening... fix that damn phone! The Nexus works (4.0.2), great, but you broke the S2.

I would think so. I don't know of a tablet that does not. If looking for a phone, the Galaxy Nexus works in high-speed (about 160 Mb/s from my tests). be aware that you may not get the full 400 Mb/s bandwidth with these resource constrained devices.
