My Apple wired keyboard doesn't work if it is plugged into an USB 3.0 port on my Samsung laptop.

As far as I understand the problem is in USB 2.0 hub built-in Apple keyboard, and it's not work well with USB 3.0 hub within laptop.

Please note that it works properly being plugged in USB 2.0 port in the same laptop.

Is there way to switch USB3 ports to USB2 mode? Or another way to get keyboard working?

The inconvenience is that USB2 ports in my laptop are located at the right side, but it's convenient to me to plug keyboard at the left.

    Does this usb3 port work with real usb3 devices? And what is your operating system ? – harrymc Jun 7 '13 at 16:18
  • OS Win 7 x64. I have no usb 3 devices to test ports. Usual devices like USB flash drive works correctly. – Jurlie Jun 8 '13 at 13:11

    Have you a proper driver for usb3 such as Renesas Electronics USB 3.0 Driver? – harrymc Jun 8 '13 at 14:02
  • No. :-). Looking for and trying to install. – Jurlie Jun 8 '13 at 14:45

    How old is the Apple Keyboard? The older USB 2.0 keyboards actually had USB 1.1 hubs and maybe that's the problem. In any case, USB 3.0 ports automatically switch to 2.0 when plugged in because the plugs are different. – Old Pro Jun 12 '13 at 2:54

It seems like your BIOS just doesn't agree with your keyboard, possibly too old to be used in such a new port.

The only suggestion I can make is to look for a BIOS update that might improve the situation, either working with that keyboard or having an option for USB2 emulation.

Otherwise, you might need a newer keyboard.


A BIOS on a IBM compatible (tm) PC used to work with PS2 port. Support for that was included in the BIOS and an old PC with an OLD BIOS will not recognise an USB keyboard.

This was a problem when poeople got the 'new' USB 1 based keyboards. An old keyboard was needed to enter the BIOS, the new one only worked after booting the OS (and with the OS the USB drivers).

Eventually (present time) we woeked around that by adding limited USB support to the BIOS. (Limited as in no support for most devices except for mouse and keyboards). This way you can use your keyboard before booting. When ther OS finally iunitialises its drivers it takes over from the old BIOS hooks.

Now we finally get to the problem. The USB3 controller is different from older USB1|2 controllers. Many BIOSses do not support it yet. (It will work fine from the OS once the OS boots and loads all drivers, including USB2 and USB3 drivers). But as long as you are in the BIOS you need to use the USB2 ports.

TL;DR; It should work:

  1. After the OS is loaded and takes over.
  2. And assuming there are no weird incompatibilities either from the USB3 implementation or because the keyboard integrated hub acts in a non-standard fashion.

Can you test the last by plugging the apple keyboard in another computer with a USB3 port?

  • At other PC (desktop) works fine. Seems the problem is in chipset drivers of my laptop. – Jurlie Jan 17 '14 at 13:10
