Linksys (Alinx) W11USB

Hello people,

I thought I would be able to get my Linksys WUSB11 802.11b USB device 
going in a jiffy using the berlios drivers. And, sure enough, they 
compiled and installed without a hitch.

However, the correct driver would not load (by hotplug) so I did an lusb 
which showed the device to be an 'Alinx Corp' device. The idVendor is 
0x13b1; the idProduct is 0x000b.

So, I changed the vendor and product ids in all the driver .c files like so:

#define VENDOR_ID_LINKSYS             0x13b1
#define PRODUCT_ID_LINKSYS_WUSB11_V21 0x000b

and then tried modprobing each module like so:

modprobe -v at76c503-i3861

However, each time, I got messages in /var/log/messages like this (in 
particular, note the firmware load failure wi th error -22):

I used the latest CVS tarball from the berlios web site, with dates like 
this:
$Id: at76c503.c,v 1.74 2005/03/08 01:33:14 jal2 Exp $

I am using a fully updated Fedora Core 3 with a 2.6.11-1.14_FC3 kernel.

I haven't yet tried turning kernel debugging on in /etc/syslog.conf.

Grateful for any assistance.
