Note that this driver comes in a .cab file and you will need to download and extract the .cab file from the zip file. Once you have extracted the .cab file remember where you had extracted the file contents too. See also the Asus mtp driver as well as the Asus adb driver on here. You can also see the ASUS UART drivers on here.
You will now have to open your control panel. This is done by opening the Device Manager (right click on My Computer, choose Manage and then find Device Manager in the left panel. Right Click on the device you wish to update. Then click update software and browse to where you had extracted the file contents.
The alternative install is much easier. Download the file and then extract the files where they are. Then right-click on the INF file. You will right-click the file”bcbtums-win8x86-brcm.inf” file and then click on install.
The Asus will then install the driver. The Windows system will then say that it has found a new hardware and installs it. It is all done within 2 seconds and it will then allow you to test the Asus hardware. See above on the picture that the INF you need to right-click on it and then left-click the “install” as you can now see. See also the optiplex 3030 aio drivers.
