Do I Need to Install Driver for atolla USB 3.0 Hub with Ethernet Adapter CH-301?

CH-301, atolla 3-port USB 3.0 Hub + USB to ethernet adapter, is a very convenient device to provide your laptop 3 more SuperSpeed USB 3.0 ports and access to stable wired Gigabit Ethernet connection.

Update: The below drivers are suitable for USB C to Ethernet adapter (301C) too. 

Update: All atolla Network interface Adapter doesn't require manual installation of driver. It is completely plug & play. If you still encounter driver issue, please contact the support team

1) Does CH-301 require a driver to install?

Technically speaking, this adapter consists of two parts: the USB 3.0 Hub part and the USB to ethernet part.

As a USB 3.0 hub, CH-301 will utilize the native USB 3.0 driver directly from the motherboard of your computer, so it doesn't require to install other drives.

As a USB to ethernet adapter, it requires to install the network interface card (NIC) driver when you plug it into the USB port of your computer.

But don't be panic when you find you don't have the driver. The atolla team has integrated the NIC driver directly into the product before we ship the products. So in most cases, when you plug in CH-301, it will install the driver automatically.


2) What if it simply can't install the driver by itself?

    I have downloaded the driver and restarted the computer, however, the RJ45 cable is still not working. It has a yellow blinking lights, and one solide green light. I am using a Macbook air 2015 on BigSur.

    thank you

    I have a question I purchased two of these units will the 2-year warranty cover both or do I need to register them separately?

    When I clicked on the Win7 option the page could not be found – error 404 came up?

    I can’t get my additional screen to work and am trying to update drivers.
    I am using Atolla USB 3.0 hub on windows 7 operating system.
    Any suggestions would be welcomed, many thanks.

    Am having difficulty connecting my Toshiba 1TB USB 3 external hard drive to the atolla 4 socket powered hub. My Windows 10 laptop doesn’t recognise the drive and the drive makes a clicking sound. When I connect the hard drive to the laptops USB 3 slot it works perfectly..

    So what’s happening? Do I need to install a new driver for the external hard drive?
