Good evening everyone.
I started using Gentoo some days ago, and after trying it out in a virtual machine, I decided to swap Archlinux with Gentoo. I downloaded the Minimal Installation CD from here, however my keyboard is not detected.
I currently have an AsRock Z77 Pro4, with an Intel Core i5-3570k, with a wireless Logitech M280 mouse attached. The latter is detected and works very well. My Trust GXT 18 USB keyboard, however, does not work at all. Actually, when booting, it works when I have to choose what to boot (I simply write "gentoo" there), but as soon as I hit enter and the installation CD boots up, it does not work anymore. So, when I have to specify the keyboard layout, I can not.

I tried with the SystemRescueCD: however, it looks like it is affected as well, since I can not choose my keyboard layout. If I start the graphical environment there, however, the keyboard works fine. I noticed it is first detected here:
Code:

[    2.799012] usb 2-1.7: New USB device found, idVendor=04d9, idProduct=a055
[    2.799013] usb 2-1.7: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[    2.799014] usb 2-1.7: Product: USB Keyboard
[    2.799015] usb 2-1.7: Manufacturer: KB

then it detects my graphics card (Sapphire Radeon HD 7950) and then a curious output comes out
Code:

Any ideas on how to solve this problem? May it be related to some command line parameter I should pass to the "gentoo" part? I also tried connecting it to both a USB 2 and a USB 3 port, but to no avail.

Check the BIOS setup for options like "USB keybord support" or "USB legacy support"

Yeah, those options are already enabled in the BIOS (USB legacy support and USB 3 legacy support). Also, I managed to install Gentoo from SysrescueCD, but the same problem persists: maybe if I install Xorg it will detect it, but I would like to know what the underlying problem is.

UPDATE: I managed to install Xfce, however the keyboard still does not work.

I finally got it. In order for my keyboard to be recognized, I enabled as built-in the Holtek HID Devices, that is, the following one:
Code:

    Device Drivers  --->
        HID support  --->
              Special HID drivers  --->
              <*> Holtek HID devices
