Thanks, but unfortunately no change. That is, still have that "Async" status flag toggling on and off in /sys/class/usb_host/usb?/registers (and the ~ 8MB/s drop in IDE throughput).

Maybe useful informateion: no problems when the disk is accessed through uhci-hcd at the same port. Only using it through ehci-hcd triggers the problem ("async" status flag toggling on/off, drop in IDE throughput).

Rene.
