I am trying to use an external "250 GB" disk via USB2 on a pretty
vanilla i386 box.  I think it has an Intel 845 chipset; the full dmesg
is at the end, as shown by a very recent kernel.  With a recent kernel
without ehci, plugging in the device results in

uhub3 at uhub1 port 2
uhub3: vendor 0x1058 product 0x0500, class 9/0, rev 2.00/0.07, addr 2
uhub3: 4 ports with 2 removable, self powered
umass0 at uhub3 port 2 configuration 1 interface 0
umass0: Western Digital External HDD, rev 2.00/1.12, addr 3
umass0: using SCSI over Bulk-Only
scsibus0 at umass0: 2 targets, 1 lun per target
uhidev0 at uhub3 port 2 configuration 1 interface 1
uhidev0: Western Digital External HDD, rev 2.00/1.12, addr 3, iclass 3/0
uhid0 at uhidev0: input=2, output=2, feature=0
sd0 at scsibus0 target 0 lun 0: <WD, 2500JB External, 0112> disk fixed
sd0: 232 GB, 16383 cyl, 16 head, 63 sec, 512 bytes/sect x 488397168 sectors

and one can 'mount_msdos /dev/sd0e /mnt' (with a long pause)
successfully, but at slow speed.

With an ehci kernel the USB2 hub is found:

uhub3 at uhub1 port 2
uhub3: vendor 0x1058 product 0x0500, class 9/0, rev 2.00/0.07, addr 2
uhub3: 4 ports with 2 removable, self powered

but then instead of attaching the disk:

ehci0: port reset timeout
uhub3: port 4 reset failed

Further, this seems to put the hard-drive in a weird state and makes
it not work any more with usb1 - even if the drive is power cycled;
using the drive in an M$ box at USB2 seems to fix it.

ehci(4) says:

     The support for hubs that are connected with high speed upstream
     and low or full speed downstream (i.e., for transaction
     translators) is limited.

I wonder if this is the issue, with the hub in the disk having a
low/full side for the hid for the front panel buttons.

Any clues would be appreciated; I can send debug info with more
options if that would be helpful.

[no cd was in the drive - it worked fine with a cd to do the upgrade
from netbsd-2 to current in the hopes of getting large-msdos support
-that part worked]
