** Description changed:
Hi, I wanted to send this bug to the Ubuntu Kernel USB Team, but couldn't
find a way to file it directly for them.
Anyway, the problem is the following:
I have an external hard drive (Toshiba PX1220E-1G25, 250 GB, 3,5'') that is
not recognized under linux (
tested on Ubuntu 8.04 and Debian Lenny). It works fine under Windows XP.
Symptoms:
* The following message is visible in dmesg: usb 5-8: new high speed USB
device using ehci_hcd and address 4
This message is repeated from time to time using different address number.
* The disk does not show up under the lsusb and fdisk -l commands.
This hdd does not have a built-in password application, so this should
not be a problem.
I have browsed around a bit and I believe that this device
is actually a Dura Micro Model 501-B101 (or maybe B112) HDD enclosure
with a 250GB hard drive (http://www.duramicro.com/501.html).
Is there a way to get it work? I am not a programmer, but would gladly
gather debug info or test kernel patches if it helps.
Thanks in advance.
Regards,
Robert

+ WORKAROUND: the problem seems to be related to the ehci_hcd module,
+ because the device is recognized if I remove this module.
