ccsniffpiper on linux

[xeonphi]

Hi!
I have try to run ccsniffer on ubuntu but get this error:

Traceback (most recent call last):
File "./ccsniffpiper.py", line 549, in
snifferDev = CC2531(handlerDispatcher, args.channel)
File "./ccsniffpiper.py", line 298, in init
self.name = usb.util.get_string(self.dev, 256, 2) # get name from USB descriptor
File "/usr/local/lib/python2.7/dist-packages/usb/util.py", line 328, in get_string
raise ValueError("The device does not support the specified langid")
ValueError: The device does not support the specified langid

Do have any ideas how to fix this?

I got this from lsusb:
Bus 007 Device 010: ID 0451:16ae Texas Instruments, Inc.

Well, your device is connected.
as far as I am concerned, I start ccs with sudo in my ubuntu VM and it works.

Hi Guys,

To be honest, I haven't really touched this in a while. But plenty of people seem to be getting it to work.

I always used these tools with the CC2531EMK modules.

Unfortunately, I can't really help much here anyway, as I left the company I was doing this stuff for and don't have any CC2531EMKs in my possession.

Good luck!

thanks you for your quick answers.
GillesDD what version of python and ubuntu are you using?
I did try with the sudo but still doesn't work.

I put a static value for the device description as a workaround. It seems that pyusb wasn't able to retrieve it directly from the device.
self.name = "TI CC2531" #usb.util.get_string(self.dev, 256, 2) # get name from USB descriptor

Hi,

Old thread I know, but wanted to put my input in re macOS Sierra.

Thanks to XeonPhi's workaround, I've now got this working under MacOS.

Steps I had to go thru'

1: Install Homebrew (http://macappstore.org/libusb/)
2: Install Libusb (same url above)
3: Install python 2.7.13 (https://www.python.org/downloads/)
4: Install pyusb (from terminal 'sudo pip install pyusb'; PIP installed with python)
5: Download ccsniffpiper
6: Edit ccsniffpiper.py using IDLE (downloaded with python, in python application folder) to set static value as XeonPhi describes above
7: run ccsniffpiper via terminal; navigate to the ccsniffpiper folder via command line then enter 'sudo python ccsniffpiper' and press return
8: press 's' and return to start capture
9: open Wireshark
10: follow instructions on ccsniffpiper cover page here at GitHub, as provided by author, to set the IEEE802.15.4 protocol preferences and to point Wireshark at the 'pipe' from ccsniffpiper
11: start capture in Wireshark

And ..... !

Have gotten it running in Kali Linux on a Raspberry Pi 3, doing pretty much the above, minus the 'homebrew' but needed to install python, libusb, python-pip, pyusb, and edit the ccsniffpiper.py file as XeonPhi suggests (which meant installing idle, which is not installed with python 2.7.13 .... but

need to launch Wireshark from terminal as follows

wireshark -k -i /tmp/ccsniffpiper &

Don;t know if 'sudo' is needed or not, but I've just done it with sudo.

I also have the same issue. Perhaps a try/catch block to set the default if it's not working?
