Cannot use the utility to probe or update firmware - ValueError: too many values to unpack (expected 2)

Hi,

I cannot use the ezsp utility to probe or update firmware for my Zigbee USB stick. The error returned is:

sudo python3 Elelabs_EzspFwUtility.py probe -p /dev/ttyUSB0

Traceback (most recent call last):
  File "Elelabs_EzspFwUtility.py", line 526, in <module>
    elelabs.probe()
  File "Elelabs_EzspFwUtility.py", line 307, in probe
    ezsp_status = ezsp.initEzspProtocol()
  File "Elelabs_EzspFwUtility.py", line 286, in initEzspProtocol
    ash_status = self.ash.sendResetFrame()
  File "Elelabs_EzspFwUtility.py", line 178, in sendResetFrame
    status, response = self.getResponse()
ValueError: too many values to unpack (expected 2)

This is what the USB stick looks like when I made the purchase. I can't tell if this model is supported by the utility.

Same issue for my 2018 Elelabs USB stick, Ember EM35x device:

openhabian@openHABianDevice:/home/elelabs/elelabs-zigbee-ezsp-utility-master$ sudo python3 Elelabs_EzspFwUtility.py probe -p /dev/ttyUSB0

I'm having the same problem on a Windows 10 machine.

FYI: Before probing (with Ubuntu 20.04 + as root → which fails for me, too) I installed (as root) the packages from requirements.txt and the output was as followed …
