Since the last generic kernel in Karmic-Updates (2.6.31-20-57) everythings seems to go fine...
On changelog are some USB-related changes, but i can't determine which is the answer.
Debian-testing, kernel 2.6.32, has the same problem.
chipset USB: AMD SB600
some ports with USB 1.1 devices connected had ohci loaded, and the port with WDPassport HDD loads ehci without any error. Large transfers ok, without resets
I hadn't any "trick" of above, I made a new instalation.
