6 in 1 memory card readers

[Kevlar <kevlarcs hotpop com>]

I am trying to get a 6 in 1 memory card reader working on my Redhat 9
machine, running a custom 2.4.20-8 kernel.

When I plug it in, I get a message on the console:

> hub.c: connect-debounce failed, port 1 disabled

I use other usb flash memory devices (usb memory sticks) etc and have no
problem with them. Any idea what could be wrong here?

The card reader device is a generic chinese made brand.
