bulkRead timeout on RZUSB on Ubuntu 12.04

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Call pnext from a RZUSBSTICK KillerBee instance.
2. Running on Ubuntu 12.04 LTS.

What is the expected output? What do you see instead?
The goal is to sniff for packets. Instead...

$ sudo ./listen.py -f 15
listen: listening on '002:018'
Traceback (most recent call last):
  File "./listen.py", line 84, in <module>
    packet = kb.pnext()
  File "/usr/local/lib/python2.7/dist-packages/killerbee/__init__.py", line 256, in pnext
    return self.driver.pnext(timeout)
  File "/usr/local/lib/python2.7/dist-packages/killerbee/dev_rzusbstick.py", line 392, in pnext
    raise e
usb.USBError: Connection timed out

What version of the product are you using?
[ ] KillerBee 1.0 (from TAR file)
[X] KillerBee beta (from SVN checkout) Revision # 36
[ ] Other:

On what operating system?
The timeout occurs only on Ubuntu 12.04 LTS. It does not occur on Mint 12.

With what Python version? (python -V)
2.7.3

Is scapy-com installed?
yes

I'm now able to reproduce on 12.04. Can people contribute to the dataset? Who 
is on an earlier version of Ubuntu still that doesn't have this issue? Python 
version and libusb version (libusb-config --version) would be helpful to see if 
it's a change there. We haven't changed the code related to this in KillerBee 
for a long time.

For me:
$ libusb-config --version
0.1.12
$ python --version
Python 2.7.3

I have a possibly related problem. Have tried on Ubuntu 12.04, Backtrack 5R2 
and Mint 13. I have also tried Mint 13 within VirtualBox on a different 
machine. Errors are the same across all. I have setup with:

sudo apt-get update
sudo apt-get install subversion
sudo apt-get install python-gtk2 python-cairo python-usb python-crypto 
python-serial sudo apt-get install python-dev libgcrypt-dev svn checkout 
http://killerbee.googlecode.com/svn/trunk/ killerbee-read-only
sudo python setup.py install

My versions are:
mint@mint ~/Downloads/killerbee-read-only/killerbee $ libusb-config --version
0.1.12
mint@mint ~/Downloads/killerbee-read-only/killerbee $ python --version
Python 2.7.3

The errors are:

I have also just tried on Mint 12 within VirtualBox. The errors are similar 
apart from an additional line at the end of zbdump and zbstumbler saying: local 
variable 'response' referenced before assignment.

Revision 39 has an attempted (simple) patch. Please let me know how it works.

Basically, the usb.USBError is ignored if e.args[0] != "Connection timed out". 
Strange, but it works in my testing so far and was suggested and verified by 
Tom S.

Requesting QA testing help. Please post errors ASAP if issues still exist.
