Hm not sure about why your command fails, but you can also try using zbdump. That's what I use to capture packets and then afterwards open them in wireshark.

Oh and I just took a look at the zbwireshark tool. It tries starting wireshark via cli first. Are you sure wireshark is installed on your device? Are you able to execute wireshark on your terminal to open it?

@LordofMisery where do you get that information from? The latest firmware is even named cc2531? For me it works fine on a Ti cc2531 from Amazon

Unfortunately, this is a known bug of this firmware, sometimes it triggers this kind of error on libusb because I think I'm doing it wrong at some point in the code. The more Zigbee devices in the area the more often it happens, other contributors reported.
