OPelerin,

You have some USB Debug on in the kernel.
In menuconfig, press / and enter debug. Almost all debug options should be off. Find the USB one, turn it off and rebuild your kernel.

Doooh!

CONFIG_USB_DEBUG=y


Thanks. Funny enough, that debug never printed anything that was connected via usb2.0.

Thanks!
