I am having trouble getting a USB pen drive to mount. I am running an up-to-date Etch box.

I have, in fact, tried two separate pen drives with the same results.

The output from dmesg shows:
------------------------------------------------------------------------------------
usb 4-4.4: new high speed USB device using ehci_hcd and address 6
usb 4-4.4: no configuration chosen from 1 choice

I see "configuration #1 chosen from 1 choice" in the second line when I
plug in my pen drive.

[...]

It seems that the system is recognizing the drive as it is being plugged in and unplugged, but that udev is not creating the device file for it. Am I missing a driver, or what?

It seems to me that things go wrong very early, already before udev is
involved. Unfortunately I do not know what or where this "configuration"
is supposed to be.

The output of lsmod is:

Here is what I get with my USB pen drive plugged in (device was created,
but it is not mounted yet):

$ lsmod | egrep 'usb|hcd'

I don't think that "usbhid" makes a difference; that is just for my USB
mouse.

What do you get with "lsusb" when the pen drive is plugged in? Maybe you
need to "update-usbids" to have the device identified correctly.

Well, as you can see, I have all of the modules loaded that you do with the exception of hid and usbhid (which are for your mouse) so that does not seem to be it.

I do not have the 'lsusb' command on my box and can not find it with 'dpkg -S lsusb'. What package is it in? I also do not have an 'update-usbids' command.
