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

Hi,
first of all i would like to thank Vladimir for his great work on Wisp.

I have problems with loading usb drivers to Wisp 2.4.20 kernel.
I'have downloaded them (usbcore.o, usb-ohci.o) from 
http://leaf.sourceforge.net/devel/jnilo/bering/latest/modules/.

The result of modprobe usbcore; modprobe usb-ohci in dmesg is following:

usb.c: registered new driver usbdevfs

According to lsmod, usbcore seems to be really loaded, but
modprobe usb-ohci ends with segfault. I've tried it on two different
PC's. At least on my one the usb works fine.

Thanks for help,
