[ale] USB device stops working

Important questions are here, other stuff mixed in the text.

   What kernel version are you running?
   Is the source vanilla? (from kernel.org) or from your distro?
   If this source is vanilla, was your prev kernel vanilla, or from your distro.
   What I'm getting at here, is maybe your distro threw in some added majic that's not in the vanilla kernels.

   It looks to me something isn't compiled in for USB and/or the device.

   usb-storage shouldn't load without usbcore, but I don't see usbcore mentioned anywhere.
   usb-core ties usb-{device} to the root usr-[uo]hci driver.
   look for more messages

No, this is just port 001 and port 002 of Hub 001.

The important item, the Root Hub.

And this is your Gizmo.

Neither do I really, but it does tell me that it is talking (handshake) to something, but maybe it can't identify it correctly.

I've actually managed to confuse myself, because my /proc/bus/usb is bone dry.

****I'm running the 2.4.10 kernel, which kernel version are you on?****

I do have this under /proc/scsi
hera:/proc # cat scsi/usb-storage-0/2
    Host scsi2: usb-storage
        Vendor: Hagiwara Sys-Com
       Product: CompactFlash R/W
Serial Number: FC0000003A70
      Protocol: Transparent SCSI
     Transport: Bulk
          GUID: 069300030000fc0000003a70
      Attached: 1

   Which is really what I expected to find on your system under /proc/bus/usb/001/00[12].

   My gizmo has an LED on top to tell me it's active.  Does yours?  Is it burning?

Try removing it and re-inserting the CF card.

For comparison, here's what I have.

   Passing thoughts... Do you have another computer you can plug your Gizmo into to see if it works? (just in case)
   Do you have any other usb devices (camera, scanner, kb, mouse, audio, Gizmo#2) you can plug and see if it is detected?

Lost in Tokyo,
