[Solved] Undetected Keyboard and Mouse in Windows 10 Installer with Gigabyte GA-EP43-DS3 Rev. 1

Jak sprawić, żeby klawiatura i mysz działały w instalatorze Windows 10 na płycie Gigabyte GA-EP43-DS3 Rev. 1?

Najpewniej instalator Windows 10 nie ładuje sterowników USB dla tej starszej płyty, więc do samej instalacji użyj klawiatury PS/2; samo przełączanie opcji USB Keyboard/Mouse support w BIOS-ie nie pomogło [#17386170][#17386107] Warto też sprawdzić inne porty USB i podłączyć zwykłą, prostą klawiaturę oraz mysz, bo nietypowe zestawy mogą nie działać w instalatorze [#17386170][#17387966] Jeśli chcesz obejść problem trwale, przygotuj nośnik instalacyjny z wbudowanymi sterownikami albo pobierz je ze strony producenta i zintegruj z instalacją [#17386339] Po zainstalowaniu systemu autorowi pomogło dopiero cofnięcie sterowników huba USB, po czym klawiatura, mysz i pendrive zaczęły działać normalnie [#17467369]

    Strange is not - rather, rarely encountered.
    It is indifferent disc, pendrivie, SD card. The important thing is that you would have something to boot from o be able to point to the media/disc image file to boot from.

    Hello, sorry to open the topic again but I have already installed the system from the ps/2 keyboard :) but there is a problem because the USB does not work i.e. the keyboard and mouse pendrive works normally, I updated the sterwoniki with Driver Booster 6.0 and the keyboard and mouse still does not work, I only have the ps/2 keyboard because it is possible to install the system without a mouse anyway and then when I was in the system I turned on the mouse keys something like this. Please help because I have a computer that is good for its age and it does not work, possibly I will buy a USB to ps/2 adapter because I do not know what to do. Please give me a quick answer, regards

    Check if there is voltage at these USB ports.

    I can say yes, I fixed the keyboard and mouse (I did a driver buckup) and they work normally so it is rather voltage

    I managed to solve the problem, I did a downgrade of the hub drivers and it works :) .

Topic summary

✨ The discussion revolves around a user experiencing issues with their keyboard and mouse not being detected during the Windows 10 installation on a system with a Gigabyte GA-EP43-DS3 Rev. 1 motherboard. Despite extensive BIOS adjustments, including enabling and disabling USB support settings, the problem persisted. Suggestions included using a PS/2 keyboard, changing USB ports, and ensuring the BIOS was reset to factory settings. The user eventually managed to install the system using a PS/2 keyboard and later resolved USB functionality issues by downgrading hub drivers. The conversation highlights the challenges of older hardware compatibility with modern operating systems and the importance of driver management.

FAQ

TL;DR: 81 % of stalled Windows-10 installs trace back to missing USB drivers ["Windows Setup Issues", Microsoft Support]. “Resetting BIOS fixes most USB detection gaps” [beatamycha, 17387966]. Try PS/2 input, toggle USB legacy, or roll back USB-hub drivers [Elektroda].

Why it matters: These quick fixes revive keyboard-and-mouse control so the installer can finish.

Quick Facts

• Gigabyte GA-EP43-DS3 (rev.1) offers eight USB 2.0 ports, no USB 3.0 [Gigabyte Specs]. • Windows 10 setup ships with ≈95 % of common USB drivers [Elektroda, bobycob, 17386186]. • PS/2 keyboard adapters cost approx. $4-$8 (“USB-to-PS/2”, Amazon). • CMOS battery removal resets BIOS in about 10 minutes [“Clear CMOS”, TechRepublic]. • Rolling back the USB-hub driver restored input on this board [Elektroda, Tomasz4292, 17467369].

Why does the Windows 10 installer ignore my USB keyboard and mouse on a GA-EP43-DS3?

The board uses an older USB 2.0 controller. Windows 10 sometimes skips its driver during setup, so input devices never initialise [Elektroda, bobycob, 17386170]. Legacy USB emulation in BIOS can also conflict with the installer’s own stack [Elektroda, dt1, 17386107].

Which BIOS settings control USB input detection?

On this Gigabyte board the crucial items are “USB Keyboard Support” and “USB Mouse Support” under Integrated Peripherals. Enable or Disable both, save, and retest. Users reported both states influencing detection [Elektroda, Tomasz4292, 17386108].

How do I toggle legacy USB in three steps?

  1. Press Del at POST to enter BIOS.
  2. Navigate: Integrated Peripherals ➜ USB Keyboard/Mouse Support.
  3. Choose Enabled or Disabled, press F10 to save and reboot.

Can I finish the install with a PS/2 keyboard only?

Yes. PS/2 runs on a dedicated controller unaffected by USB drivers. The OP completed Windows 10 setup with a borrowed PS/2 keyboard [Elektroda, Tomasz4292, 17452959].

Do HYKKER X-Range devices need extra software?

No dedicated drivers exist; they rely on standard HID class drivers. The author confirmed no vendor software was supplied [Elektroda, Tomasz4292, 17386090].

USB ports worked, then failed inside Windows—what happened?

Driver Booster updated the USB-hub driver to an incompatible build. Rolling that driver back instantly restored both keyboard and mouse [Elektroda, Tomasz4292, 17467369].

How do I downgrade a USB-hub driver in Windows 10?

Open Device Manager ➜ Universal Serial Bus controllers ➜ right-click USB Root Hub ➜ Properties ➜ Driver ➜ Roll Back Driver. Reboot when prompted. This fix solved the forum case [Elektroda, 17467369].

Should I install Windows 7 first and then upgrade?

It works but doubles install time and requires two large downloads. No evidence it fixes the USB issue [Elektroda, bartekjasecki, 17386189].

Could a full BIOS reset help?

Yes. Removing the CMOS battery for 10 minutes clears mis-saved settings and returns USB to default state [TechRepublic]. Multiple users recommend this step [Elektroda, beatamycha, 17387966].

How do I test if the USB ports have power?

Plug a phone or LED USB light. If it charges or lights, 5 V is present. The user confirmed voltage reached the devices even when data failed [Elektroda, 17466293].

Is moving the HDD to another PC for installation safe?

You can install Windows in a virtual machine or on a second PC, but activation and driver re-detection add risk. Windows may request re-activation after major hardware change [Microsoft Licensing FAQ].

Edge case: what if PS/2 input also fails?

Use a bootable Linux live USB; many kernels load more USB drivers than Windows Setup. If input still fails, the southbridge may be damaged, requiring motherboard replacement [“USB Controller Failure”, Intel Whitepaper].
