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?
- Press Del at POST to enter BIOS.
- Navigate: Integrated Peripherals ➜ USB Keyboard/Mouse Support.
- 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].
