[Discuss-gnuradio] USRP failed to attach after NetBSD upgrade; solution is update libusb

[Greg Troxel]

exec summary:

  After update of NetBSD to recent current, all usrp programs failed
  to find the USRP.   Rebuilding libusb solved the problem.

details in case it's helpful for anyone:

I'm trying to run a USRP on battery power, and using a new notebook
(T60) at the same time.  I'm running NetBSD-current, and others in my
group have used this fine.

(For the curious, I'm using a 12V-5V DC-DC converter, and a 6.5 Ahr
lead-acid battery, with a West Mountain Radio RigRunner 4005 to
distribute power to both the USRP and a Novatel GPS unit, all bolted
into a Radio Flyer all-terrain wagon.)

On boot my system detects

ugen0 at uhub3 port 2
ugen0: STMicroelectronics Biometric Coprocessor, rev 1.00/0.01, addr 3

and then when I plugged in the USRP.

ugen1 at uhub4 port 5
ugen1: GNU Radio USRP USRP Revision 2, rev 2.00/0.02, addr 2

usbdevs -v reports:

If I run test_usrp_standard_rx, it failed to find the USRP.

I solved this by rebuilding libusb; I had not rebuilt it since
upgrading NetBSD to a newer version of current.  Then, after testing,
I find the USRP at the right address.
