Title: slow USB 2.0 drive: it's mounted as USB 1.0, not USB 2.0! Status in linux package in Ubuntu: Incomplete Bug description: In gutsy 7.10 dist-upgraded to the max: Ubuntu 64-bit sometimes does not mount USB 2.0 devices as 2.0. 1) plugin in the USB drive 2) mount it if not automounted (sometimes it doesn't) 3) right-click, properties in nautilus, go to drive tab, see speed "12 Mbps" 4) umount it, unplug it 5) sudo rmmod ehci_hcd 6) plugin the USB drive 7) sudo modprobe ehci_hcd 8) mount it if not automounted 9) right-click, properties in nautilus, go to drive tab, see speed "480 Mbps" Something is horribly wrong at recognizing the proper USB speed mode of external drives. From /var/log/messages: note how the first time the drive is mounted properly as high speed, the second time as slow, then as high speed again with the trick of modprobe'ing the ehci_hcd driver. Somehow, the second time the driver sees the same USB hard drive, it fails to recognize it as USB 2.0. (when I modprobe the driver, the USB mouse and keyboard are also recognized, don't be confused by these). If you need more info let me know.
