I'm terribly sorry for the delay (I spent this afternoon rehearsing with 
my band).

This is probably caused by the fact that libusb doesn't work very well 
when the kernel module scanner.o is loaded.

To see if the module is loaded try this:

[shell]# lsmod

If there is a module named scanner, unload it like this

[shell]# rmmod scanner


Check if it was unloaded (by doing lsmod again).
If it was unloaded try using the testtool.
If the module is still loaded, do rmmod scanner until it is unloaded.

That should do the trick.

NOTE: Always make sure the scanner module is unloaded (a good method is 
by not even compiling it in the kernel).
