Hello, Lukas!
 (and every one else =)

Just noticed new ehci.c commit today and decided to give it a try.
My USB2 external HDD now attaches correctly and I can even mount it.

umass0: vendor 0x0840 USB 2.0 Storage Device, rev 2.00/0.01, addr 2
umass0: SCSI over Bulk-Only; quirks = 0x0000
umass0:3:0:-1: Attached to scbus3
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <USB 2.0 Storage Device 0100> Fixed Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: 78533MB (160836480 512 byte sectors: 255H 63S/T 10011C)

It gives me about 6,5 Mbytes/s transfer speed, but dies after transfering
about 50Mb with:

umass0: Invalid CSW: tag 4593 should be 4602
ehci_idone: need toggle update status=10000d40 nstatus=10000d80
ehci_idone: need toggle update status=10000d40 nstatus=10000d80

Hope this helps to improve EHCI somehow :)

Cheers,
        AL.
