You install AULA's driver, open it, and it tells you nothing is connected, even though the mouse is moving the cursor perfectly well. With the AULA SC620 Contour that usually has one cause: the mouse is paired over Bluetooth. The SC620 Contour driver is built to talk to the mouse on its receiver or cable, and knowing that saves a lot of reinstalling and restarting.

Quick Answer

AULA's configuration software reaches the SC620 Contour on Windows only through the USB dongle or a wired link, never through a Bluetooth 5.3 pairing. To remap buttons or change DPI, polling rate, sleep time or lighting, plug in the 2.4GHz receiver or the USB cable, then open the driver again. Bluetooth still works normally for everyday use; it simply is not the link the software uses. At Evetech, the SC620 Contour costs R349.

🔍 Why Bluetooth leaves the driver blind

A mouse on Bluetooth is handled by the operating system's generic pointer support, which is why it moves and clicks with no setup at all. The 2.4GHz receiver and the cable give the PC a direct USB connection to the mouse, and that is the channel AULA's software is designed to use for sending new settings.

So the driver is not broken, and neither is the mouse. It is looking for the device on a link that is not in use. Switching over fixes it immediately.

Quick fix checklist

  • Plug the 2.4GHz receiver into a free USB port, or connect the cable.
  • Set the mouse to the matching mode.
  • Close and reopen the driver.
  • If it still shows nothing, try a different USB port directly on the PC rather than through a hub.

⚙️ What lives in the driver

Everything you would want to customise sits in one place:

  • Button remapping, including the dedicated Fire button, which runs one mapped command per press.
  • Macros, recorded and assigned to programmable buttons.
  • DPI, across six levels: 800, 1600, 3200, 4800, 8000 and 12,000.
  • Polling rate, set to 1000Hz.
  • Sleep time, which decides how quickly the mouse powers down when idle.
  • RGB lighting, including brightness and speed, glowing through the honeycomb shell.

The practical approach is to set all of this once over 2.4GHz or cable, then use whichever link suits the day.

📶 Bluetooth still has a job

Nothing about this makes Bluetooth 5.3 a lesser mode for normal use. It is the handy choice for a laptop with no spare USB port, or for a second device you switch to during the day. The mouse also lists support for Windows, macOS, Linux and Android, so Bluetooth is how it reaches machines where you would rather not plug anything in.

For gaming on a desktop, the receiver remains the better everyday link anyway, since it is also where you manage the 1000Hz polling in the driver.

If you are comparing the SC620 Contour with other tri-mode mice, Evetech's gaming mice category lays out the options, and the wireless mouse page groups the cable-free picks. The mouse weighs 67g, runs on a 400mAh battery and comes in black or white.

Frequently Asked Questions

My driver shows no mouse over Bluetooth. What is wrong?

Nothing is faulty. AULA's driver works with the mouse over the 2.4GHz receiver or cable on Windows, not Bluetooth 5.3.

Which settings can only be changed in the driver?

Button remapping, macros, DPI, polling rate, sleep time and RGB brightness and speed.

What must be connected for the driver to find the mouse?

Either the 2.4GHz receiver in a USB port or the USB cable, with the mouse set to that mode.

Can the mouse be used normally on Bluetooth?

Yes. It moves and clicks as usual; you just cannot change its settings from the driver on that link.

Is the polling rate controlled from the same software?

Yes. The 1000Hz setting is part of AULA's driver, alongside DPI and lighting.

How is the warranty handled?

Support runs through Evetech, where the mouse is listed with a 1 Year Local Warranty.
