There seems to be problems in the EHCI driver. I have an USB 2.0 external hard disk, that when running in that mode, only works in readings, when trying to write something it automaticly get disconnected, and data lost of course. It works fully in USB 1.1 mode, and in Windows and MacOS X in USB 2.0 mode. I tried it in nVidia nForce and SiS (with VIA USB) chipsets, with same results.
