dh1tw / streamdeck Goto Github PK

I'm trying to get this to work on linux without sudo but it's failing to open the device.

hidapi: failed to open device

I created a /etc/udev/rules.d/51-usb-streamdeck.conf with the following:

SUBSYSTEM=="usb", ATTR{idVendor}=="0fd9", ATTR{idProduct}=="0060", GROUP="plugdev", TAG+="uaccess"

I've added my user to the plugdev group but it still fails to open the device.

Does anyone have a working config?

I started using this library but I made some modifications.

First, I switched to karalabe/hid so I could use: SendFeatureReport() and GetFeatureReport()

Second, the packet to control the brightness is as follows:

0x03, 0x08, perc, 0xff, 0xff, 0xff, 0xff, 0xff, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x30,
0x69, 0x92, 0x2a, 0xf8, 0x02, 0x00, 0x00,

Where perc is some int between 0 - 100.

My device is a 15 key Streamdeck and the FW is 1.02.005

To get the firmware using GetFeatureReport set the report ID to: 0x05
To get the SN the report ID is: 0x07

This was discovered by running the Elgato stream deck software along side Wireshark and USBpcap on Windows 10.

I have been using the following sources as reference (along with this library):

• https://github.com/Julusian/node-elgato-stream-deck/blob/master/packages/core/src/models/base.ts#L199
• https://github.com/abcminiuser/python-elgato-streamdeck/blob/dc94c1718cbb01391790ba09de4977e8fcc19b8a/src/StreamDeck/Devices/StreamDeckMini.py#L99
• https://gist.github.com/cliffrowley/d18a9c4569537b195f2b1eb6c68469e0

And these references seem to be for older firmware's, hence my reason for opening this issue which is more of an FYI.

Perhaps if I have time I can submit a PR, however as I only have the 15 key deck I do not know if this applies to the others.

Probably the function should just be removed.

When i'm using the lib i always have the following error, even if the stream deck is plugged in :

Does not work with the current model of the 15 key Stream Deck. I have tried changing the ProductID which makes the hardware detectable but none of the examples run. When I try to run them they just hang indefinitely.
