[Ubertooth-general] PyUSB problems

[Jordan J. R. <jj...@co...>]

All,

Not sure what changed, but for some reason I can't run any of the
Python specan tools.

jjriggs@tomcat:~/ubertooth/trunk/host/specan_ui$ python specan.py
Traceback (most recent call last):
  File "specan.py", line 70, in <module>

It seemed to be working last night. The only thing I know I did was to
add a rule so that I can open the Ubertooth without running as root. I
can't imagine how that would cause this, however.

Thanks,
Jordan
