Re: [leaf-wisp] usb.c - unable to handle kernel NULL pointer

Grab the latest "beta" image from 
http://www.hazard.maks.net/wisp-dist/downloads/wisp-dist_1.3.1p30_img.bin

Grab archive with modules from 
http://www.hazard.maks.net/wisp-dist/downloads/wisp-dist_kernel-2.4.25_modules.tar.gz

Extract usb* modules from the archive, and scp them to /modules on a 
running wisp-dist image, save & reboot. After that you should be able 
to load them by doing usual "insmod" commands.
