My Stream Deck doesn't seem to have a USBMODEM device on my iMac

[aseedig]

Hi community,

My Stream Deck is working fine so far. However, when I use Python to connect to the device, I always get the probe error. All required plugins are installed but it seems Stream Deck is not listenig on any port. I cannot find a hint of the stream deck usbmodem on my system. The error says:

StreamDeck.DeviceManager.ProbeError: ('Probe failed to find any functional HID backend.', {'libusb': TransportError("No suitable LibUSB HIDAPI library found on this system. Is the 'libhidapi.dylib' library installed?")})

I have installed the Stream Deck software version 6.1.0 (18521). The Firmware on my Deck is 1.01.000. The iMac is on OSX Ventura 13.3.1 (22E261). I have all the libraries required installed and spent my weekend trouble shooting the issue. I came to the conclusion something is not right. Is there an additional software to be installed on the Mac to have the USB modem initialised when Stream Deck starts? As I said, all the libraries required to work under Python3 are installed and all dependncies seem to be there. But no usbmodem.

Any help is appreciated.

Kind regards

Axel

Hi Axel,

Unfortunately, we don't have any HID documentation to share publicly, however, if you are using Python, you might find this project helpful: https://github.com/abcminiuser/python-elgato-streamdeck.

Hi Zack,

sorry for the late reply. I was out on a business trip and just returned.
I have downloaded the stuff from the link.

The streamdeck library is already installed on my system. All the depencies are fullfilled. However, when I try to run one of the example scripts (exampe_deckinfo.py) I get an error message:

aseedig@DESKTOP-HBIE53J src % python3 example_deckinfo.py
Found 1 Stream Deck(s).

Traceback (most recent call last):
  File "/Users/aseedig/Downloads/StreamDeck/python-elgato-streamdeck-master/src/example_deckinfo.py", line 52, in <module>
    deck.open()
  File "/Users/aseedig/Downloads/StreamDeck/python-elgato-streamdeck-master/src/StreamDeck/Devices/StreamDeck.py", line 155, in open
    self.device.open()
  File "/Users/aseedig/Downloads/StreamDeck/python-elgato-streamdeck-master/src/StreamDeck/Transport/LibUSBHIDAPI.py", line 384, in open
    self.device_handle = self.hidapi.open_device(self.device_info['path'])
  File "/Users/aseedig/Downloads/StreamDeck/python-elgato-streamdeck-master/src/StreamDeck/Transport/LibUSBHIDAPI.py", line 213, in open_device
    raise TransportError("Could not open HID device.")
StreamDeck.Transport.Transport.TransportError: Could not open HID device.

I am not sure what I am missing here. I wanted to use the stream deck xl with X-Plane and use the PilotDeck solution. That is the point where I get the [...] raise ProbeError("Probe failed to find any functional HID backend.", probe_errors) [...] error.

This error was the reason I contacted Elgato Support and they pointed me to GitHub. I went to so many different troubleshooting processes so far and your attempt seems to be another dead end.

Don't get me wrong, I am not blaming you. Quite the opposite. I am grateful for any help, but I usually program in SQL and Java script and not in Python. I do Python for some minor things and have written some Python scripts in the past, but I am far from professional in Python.

Maybe you can help me here?!

Looking forward to hear from you.

Best

Axel

Hi Zack,

I did some more testing. I did quit the stream deck software and the scripts are working.
Do I assume correctly, that the Python scripts only work, if there is no Elgato Stream Deck Software running?

If so, how does that work with plugins? Is this a limitation? Is there a way to get this working together?

Thanks in advance.

Kind regards

Axel
