Here?  Why not a gumstix list?  Or maybe you've already tried there..

So why doesn't it work?  Something must have changed for it to have
stopped working.

I've not toyed much with the USBNet but from a quick look at the kernel
source I see...  (linux-2.6.11gum/drivers/usb/gadget$ vi ether.c)

/* Some systems will want different product identifers published in the
 * device descriptor, either numbers or strings or both.  These string
 * parameters are in UTF-8 (superset of ASCII's 7 bit characters).
 */

static ushort __initdata idVendor;
module_param(idVendor, ushort, S_IRUGO);
MODULE_PARM_DESC(idVendor, "USB Vendor ID");

static ushort __initdata idProduct;
module_param(idProduct, ushort, S_IRUGO);
MODULE_PARM_DESC(idProduct, "USB Product ID");

So you should be able to pass vendor and product IDs to the module on
insertion, but I believe it will have default values other than 0000.
Maybe your gumstix has died?  Or your Windows have a bad virus?

Also, a reminder to keep line lengths below about 70 characters.
Outlook can do this automagically I believe, if you ask it to.

James.
