I just wanted to make a note on your issue tracker about a problem I 
encountered. Solution is included.

**Problem:** I have compiled libusbx and installed on a machine running RedHat 
6.3. I compiled a program which requires hot plug support without issue. 
However, when running the program, hot plug support was not detected (libusbx 
configured with udev enabled).

**Solution:** Run ldconfig to ensure the runtime linker loads in the correct 
libusb library at run time. RedHat comes preinstalled with libusb and was 
linking that into my application instead.

Another side effect was the lack of log messages when specifying 
`LIBUSB_DEBUG=4` prior to running the application.

Thanks for the great work on libusbx. I've been able to develop a service for 
driving a filter wheel within a couple of days thanks to all of the libusb[x] 
team's hard work.
