Libusb1 not the solution to USRP crashing

I just discovered the not well published --with-fusb-tech=libusb1 option
to configure, hoping to resolve the USRP1 non-uhd crashing issues myself
and one other person are seeing when the flowgraphs do a lock or stop.
Unfortunately, I still see the same lockup, which rules out any
libusb-0.1 possibilities. I removed libusb-devel from my system and
recompiled gnuradio with the libusb1 option. You can see libusrp in the
ldd here as well.

Well, that’s too bad. I think you’d mentioned that UHD cleared up the
crashing problem, yes?

Also, Thomas T. talked about the “–with-fusb-tech” option for
“configure” on this list
just a couple of days ago. I actually recall it from last year or
so, but haven’t ever had to
use it.

Is there an error code given when this occurs? and when you attempt to
restart after it crashes?
