AULA HE / WIN Keyboard WebHID Fix on Linux

Fix for AULA HE/WIN keyboards not being detected by the web configurator on Linux.

Problem

The browser could not access the keyboard HID device through WebHID/WebUSB.

Solution

1. Get Vendor ID and Product ID

Run:

lsusb

Example output:

Bus 003 Device 002: ID 2e3c:c365 WIN 68 HE

• Vendor ID: 2e3c
• Product ID: c365

---

2. Create udev Rule

Create the rule file:

sudo nano /etc/udev/rules.d/99-aula-win68he.rules

Add:

SUBSYSTEM=="hidraw", ATTRS{idVendor}=="2e3c", ATTRS{idProduct}=="c365", MODE="0666"

Replace the IDs with your own keyboard IDs if necessary.

---

3. Reload udev Rules

sudo udevadm control --reload-rules
sudo udevadm trigger

Reconnect the keyboard after running the commands.

---

4. Enable HID Access in Chrome/Chromium

Open:

chrome://settings/content/hidDevices

Enable:

Sites can ask to connect to HID devices

---

5. Open the Configurator

Example configurator used:

https://hed.aulacn.com/

Now the browser should be able to detect and connect to the keyboard normally.

Notes

• Works for Chrome/Chromium/Edge
• Uses Linux hidraw permissions through udev
• Required for WebHID access from the browser
