Hi Mikkel,

usb 2-2: new high speed USB device using ehci_hcd

That is another reason your drive is slow. You are connected at USB
1.1 speeds, instead of USB 2.0 speeds.

new full speed USB device using ohci_hcd

It does not make a lot of sense, but the speeds go:

slow speed
high speed
full speed

Hi,

This is from tuxdera:
"USB is running in Low-Speed (0.1875 MB/sec) or Full-Speed (maximum
1.5 MB/sec) mode instead of High-Speed mode (maximum 60 MB/sec)."
from linux-usb:
"http://www.linux-usb.org/FAQ.html#gs6";

so:
low-speed - uhci
full-speed - ohci
high-speed - ehci

no?
