[opensuse] Repeated: Copy speed (USB / openSUSE 10.1)

yesterday evening I copied some files from my USB 2.0 MP3 Player (Arcjos AV380) to the desktop.

Unfortunately, I was quiet surprised by the speed I got of this action.

a hdparm -t /dev/sdc showed it would copy at 1MB / sec (which is about USB 1.1), while I'm quiet sure I was using the USB 2.0 ports of the computer (tried different ports, and the board only HAS 2.0 ports.

Is there anything I missed in tweaking / loading USB 2.0 support? ok, I admit, the mainboard (Asus P5LD2 Deluxe) I have already gave me some surprises when installing Linux (I wanted to activate RAID0 over two discs, as the board should support RAID, but the installer detected a software raid).

Thanks for some advises, Dominique
