[Discuss-gnuradio] Ubuntu 12.04 B100 issues

[bmod]

Hi,

Is anyone successfully using a B100 with Ubuntu 12.04? I rebuilt a
system recently and now I am continually getting seg faults and "Got a
data packet with unknown SID" errors on my Z77 based Ubuntu system.

I'm using the build-gnu-radio script and it's grabbed the latest uhd
images. I have a rtl-sdr like device which seems to be working fine but
attempting to run say the uhd_fft gives me;
UHD Error:
    Got a data packet with unknown SID 6553599

UHD Error:Segmentation fault (core dumped)

dmesg shows;
[ 2722.100287] uhd_fft[6089]: segfault at 220 ip 00007f902ead12db sp
00007fff181949c0 error 4 in i965_dri.so[7f902ea66000+c2000]

I checked the archives and someone mention it could be related to the
version of libusb? Is there any particular versions of libusb i should
be using?

Thanks for the help.

Bill
