Hi Andreas,

I think you mentioned in another thread that the "why" part of your 
question has been addressed. As for the location of libusb-1.0.la - it 
looks like Richard previously missed one of my commits moving 
libusb-compat, and just merged it to oe-core master:

http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=198f2ac06e60245750a2c6561b8c8e2eaa93f6be

Does this fix the issue?

I may be hard to reach tomorrow, so I hope RP or Mark Hatle can field 
any further questions for me.

Scott
