[RESOLVED] Partial Incompatibility with TEX Shura

[redyoshi49q]

One of my keyboards is the TEX Shura, which is shown as "04d9:0532 Holtek Semiconductor, Inc. USB-HID Keyboard" under lsusb in Linux; since this listing is the only one that's added when the device is plugged in, I'm inclined to suspect that there's no internal USB hub in the device.

After updating the firmware to v1.0.3 (the Shura did not function with the firmware on the device when first received at all), the Shura's keyboard now functions over the device as expected. However, any attempt to use the Trackpoint-style pointer on the keyboard causes the SterlingKey to vibrate and the LED indicating the active paired device to briefly turn off; no Trackpoint-related data is transmitted over the device. When plugged directly into my laptop via USB, though, the Shura's Trackpoint-style pointer functions as expected.

Let me know if there's any other information that I can provide on my end to help.

Hello!

Since the keys work, I'm sure it's not recognized as a HUB, otherwise it wouldn't work at all.

I'm glad the new firmware at least partially fixed it. It seems that when you use the trackpoint, SterlingKey crashes and restarts, as indicated by the vibration and LED turning off and on. That means that it's receiving the trackpoint data, so I think that's a good sign.

There's probably an issue in the HID descriptor, I'm probably (hopefully) just parsing something wrong, which can be fixed with an update.

To verify this, could you please do the below?

Connect SterlingKey to a computer using the type c port (like you did when you updated it), while also having the keyboard connected to it. Then go to https://sterling-key.com/updater/ and below Console click on Start. It will open a popup, you will select the first (and probably only) device that shows up in that popup and then click Connect. Lastly, click Reset and it will give you some output. Wait until it is connected to your computer via Bluetooth, and use the trackpoint. It will crash and reset and show some duplicate logs, that's fine. Copy and paste all the output here, so I can read it and see if the "mouse" descriptor is missing.
You can safely unplug SterlingKey from the computer now.

Thank you.

This is the output that I get from the console:

[Alex]

Thank you for the output.

I see that the mouse report is missing. I think I know why, I'll get back to you in a bit.

[Alex]

Hey, could you try again with version 1.0.4-beta-3?
Make sure to unpair and pair again, as this is changing the HID Descriptor and it needs to be re-paired.

[redyoshi49q]

After updating the firmware to v1.0.4-beta-3 and re-pairing the SterlingKey's Bluetooth connections to my laptop and phone, I can confirm that the Shura's keyboard and Trackpoint-style pointer are both functioning through the SterlingKey as expected. Thanks for the prompt update.

[Alex]

Amazing, glad it's working now, enjoy!
