There's three things you can do.  First, always CC: messages like this to 
the USB development mailing list.  It can be useful to other people 
working on similar problems, it's good to have these things publically 
archived, and other people on the list might be able to help you more than 
I can.

Second, post the contents of your /proc/bus/usb/devices file and the
output of lsusb -v with your device attached (whether or not your driver
is loaded shouldn't matter).  To make it work you will probably have to
use Linux 2.4 for this.

Third, you should try configuring your 2.6 kernel to turn on USB debugging
and post the dmesg log for the time when you plug in your device.  It
might contain error messages that would explain what's going wrong.  In
fact, not long ago I made a change to the code that does enumeration under
2.6 and it is highly likely that it is detecting a problem with your
device that the code in 2.4 did not detect.
