Agent doesn't see keyboard

[lotusnopes]

Hello,

I haven't updated my UHK in a while; went to update the agent and it's not recognized. I went through the older releases and the latest release that will recognize it is 1.2.2, but I'm unable to update the firmware on that release.

output from running the 4.0.2 appimage agent:

Please, run the app image with the following arguments -- --print-usb-devices. The first 2 dash is important. And share the result with me.

Is the keyboard directly connecting to the computer or do you use any USB hub, KVM switch or other too?

[lotusnopes]

I usually use it with a monitor KVM, but I've tried it both ways, and received the same result each time. Here's the result of the preceding instructions: ./UHK.Agent-4.0.2-linux-x86_64.AppImage -- --print-usb-devices 19:13:37.134 › [Electron Main] command line arguments { 'print-usb-devices': true } 19:13:37.138 › [Electron Main] init services. 19:13:37.138 › [Electron Main] packagesDir: /tmp/.mount_UHK.AgSkZMru/resources []

Weird, the hid-raw library can't read the devices list. It is looks like a security settings does not allow to Agent to access to HID devices.

You wrote the 1.2.2 version of Agent recognises the keyboard. I compared the 1.2.2 and 1.2.3 and we did not do any devices communication related change or updated any dependency that could affect the communication.

07:41:02.522 › [DeviceService] Udev info: Ok looks like the udev rules are up to date.

Could you review your security settings? I think there is a setting that blocks the access of Agent.

[lotusnopes]

That makes sense, as if I run it with sudo it recognizes the keyboard, but the application screen is blank.

Per your request, I'm a bit confused as to what you'd like me to check; are you referring to apparmor settings, udev file permissions, etc?

[ert78gb]

Based on the logs your udev file is up-to-date [DeviceService] Udev info: Ok, but you can find the expected udev rules in https://github.com/UltimateHackingKeyboard/agent/blob/master/rules/50-uhk60.rules

Linux is a highly customisable operation system, so I can't help you what should you check.

If you share the logs when Agent runs under the super user maybe I could investigate what is the reason of the blank screen.

I got it figured out. I ended up going back to Agent 1.2.1, flashing my firmware back to the old packaged firmware, then moving to 4.0.2 and updating from there. Thank you.
