dmesg shows many entries like this:
new high speed USB device using ehci_hcd and address 10 usb 5-3: device descriptor read/8, error -110 usb 5-3: device descriptor read/8, error -110
Googling this message doesn't seem to provide much help.
I have unpluged the device and even rebooted the computer. However, after a reboot, the /dev/sdb* files are still missing.
The device files should be created by udev automatically when you pluging the device, or boot the PC.. When you un/plug the device you should see some info in dmesg. Perhaps you have some kind of error occurring. you could try rmmod "ehci_hcd" to try using USB 1.1 instead of usb 2.0. You could also try plugging it into a different hub or usb port on the PC.
I'd run a tail -f on /var/log/messages (or wherever your kernel messages go) so you can see what's happening as you plug / unplug the device. In Gentoo, the default for syslog-ng is to have it default log to tty12 so you can just flip over there. -- HTH Eric
