FAQ

Q. It's not working on linux!
- A. On linux, you may need to run as root for it to work. You can try setting a rule for non-root users to access the device.
  Create the rule file:
```
sudo vim /etc/udev/rules.d/100-bigred.rules
```
  and add the following:
```
SUBSYSTEM=="input", GROUP="input", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="7476", ATTRS{idProduct}=="13", MODE:="666", GROUP="plugdev"
```
  Afterwards, you can reload the service:
```
sudo udevadm control --reload-rules
```

Q. What's the vendor ID and product ID?
- A. The vendor ID is 7476. The product ID is 13.
