Maybe you want to try:

Download the three files below into a new directory and type 
"make install"  (to uninstall type "make deinstall")
http://home.c2i.net/hselasky/isdn4bsd/privat/usb/Makefile
http://home.c2i.net/hselasky/isdn4bsd/privat/usb/new_usb_1_5_4.diff.bz2
http://home.c2i.net/hselasky/isdn4bsd/privat/usb/new_usb_1_5_4.tar.bz2

Type "make help" to get more help.


My USB driver will automatically re-probe all USB drivers when you load a new 
USB module. Be aware that you have to rebuild the kernel and all USB modules 
after the install.
