usb interface to Toshiba PDR-M4 cam hasn't worked since 2.4.5

If there's a usb list this would be more appropriate in, please let me
know.

I have a Toshiba PDR-M4 digital camera with USB interface, which
appeared as
a scsi device attached with usb-storage in linux-2.4.5, but hasn't
worked in
any kernel since then.  Here's a snippet from dmesg from 2.4.5, with a
successful negotiation with the camera (and its 128MB smart media card).
The
usbcore, usb-uhci, usb-storage, and sd modules are already loaded at
this point.

And here's dmesg output from the same operation with 2.4.13:

   * turn camera to 'data' mode *
 hub.c: port 2 connection change
 hub.c: port 2, portstatus 101, change 1, 12 Mb/s
 hub.c: port 2, portstatus 103, change 0, 12 Mb/s
 hub.c: USB new device connect on bus1/2, assigned device number 6
   * 4-second pause *

 hub.c: port 2, portstatus 103, change 0, 12 Mb/s
 hub.c: USB new device connect on bus1/2, assigned device number 7
   * 4-second pause *
 usb_control/bulk_msg: timeout
 usb.c: USB device not accepting new address=7 (error=-110)

And no more messages until I turn off or disconnect the camera.  It
never
procedes to initialize usb-storage on this device.

The same errors ("usb_control/bulk_msg: timeout" and "USB device not
accepting
new address=7 (error=-110)") have occurred with every kernel since 2.4.6
when
I attempt to attach this camera.  I don't believe it ever worked with
2.2.18/.19
either, but it did work with 2.2.17 with Alan's usb patches.
