Re: [Patch-gnuradio] [PATCH] Fix config script to correctly identify libusb-legacy.

[Michael Dickens]

Hi Mark - There's more to the issue that what you changed, but thank you for 
the patch and the reminder to me to check in my version of it -- you did the 
submission correctly!  I'm almost to the point of having the libusb-legacy 
changes ready for testing.  I'll get them checked in either Monday or Tuesday.  
Sorry for the delay. - MLD
