I tested recompiling the test program against the last binary snapshot, 
and I'm not experiencing any issue. I tried both shared, against the 32 
bit DLLs from the snaphost (both of them) and static against the static 
multilib MinGW32 libusb-1.0.a from the snapshot, and in each case I got 
a successful open. Below is some sample output for the static version.

$ gcc -o lsusb lsusb.c -I. -L/e/dailies/2010.08.19/MinGW32/lib/ 
-lusb-1.0 -lsetupapi -lole32

$ ./lsusb.exe

If you see this issue again, can you please provide more information 
about how you compiled your sample?
