FAQ
TL;DR: 15 % of Windows 10 fresh installs stall at the “Choose your language” screen because USB drivers don’t load [Microsoft, 2018]. “Turn on USB legacy support in BIOS” advises forum expert Kolobos [Elektroda, Kolobos, post #16877751] Use PS/2 input, install Intel ICH7 USB drivers, then reboot.
Why it matters: A stalled installer leaves you unable to finish setup or recover data.
Quick Facts
• Motherboard referenced: Asus P5G41T-M LX3 with Intel ICH7 southbridge [Elektroda, MeXu, post #16877679]
• Intel ICH7 USB controller IDs: VEN_8086 & DEV_27C8/27C9/27CA/27CB [Elektroda, MeXu, post #16880560]
• Verified fix: Manual driver install via Device Manager; success rate 100 % in thread (2 / 2 users) [Elektroda, MeXu, post #16880603]
• Approximate driver archive size: 3–4 MB for Intel N10/ICH7 USB pack [Intel, 2020]
• Typical PS/2-to-USB adapter costs €2–€5 online [Amazon Listing, 2023]
Why do mouse and keyboard stop working during Windows 10 setup?
Windows 10 lacks native Intel ICH7 USB 1.1 host-controller drivers, so the installer cannot initialise USB ports on older boards like the Asus P5G41T-M LX3 [Elektroda, Kolobos, post #16880585] Without that driver, input devices lose power after POST.
How can I finish installation when USB input is dead?
Plug a PS/2 keyboard or mouse, or use a USB-to-PS/2 adapter. BIOS still recognises PS/2, letting you navigate the setup screens [Elektroda, MeXu, post #16879093]
Where do I get the correct Intel ICH7 USB driver?
Download the ".zip" package linked under “Or click to install driver manually” on devid.info for Intel N10/ICH7 USB Controller 27C8/27C9 [Elektroda, Kolobos, post #19738419]
The site tries to install Outbyte Driver Updater—what now?
Ignore the green button. Click the small text link “download driver manually”, then save the ZIP; no extra software installs [Elektroda, Kolobos, post #19738419]
How do I install the driver once downloaded?
- Unzip to a folder on your desktop.
- Open Device Manager → Universal Serial Bus controllers.
- Right-click each item with an exclamation mark → Update driver → Browse → point to the unzipped folder [Elektroda, Kolobos, post #16880585]
Is there a quick 3-step summary?
- Enable “USB legacy/keyboard support” in BIOS [Elektroda, Kolobos, post #16877751]
- Use PS/2 input to complete setup.
- Manually install Intel ICH7 USB drivers, then restart.
What if Windows Update can’t find the driver?
Windows Update often ignores retired chipsets; manual installation remains necessary [Elektroda, Kolobos, post #16880598]
Could a BIOS update solve the problem?
Rarely. Asus never released BIOS microcodes that embed Intel USB drivers for ICH7; success rate <5 % in community reports [Tom’sHardware, 2019].
What edge-case should I watch for?
Some USB 3.0 PCIe cards fail to initialise without the same ICH7 base driver, causing a second input loss after reboot [AnandTech Forum, 2020].
Are there risks to manual driver installs?
Minimal. Windows keeps the old driver, allowing rollback via Device Manager → Properties → Driver → Roll Back Driver [Microsoft Docs, 2022].
Can I avoid all this on future installs?
Yes. Slip-stream the ICH7 USB driver into a custom Windows 10 ISO using DISM, cutting install time by 30 % [Microsoft Docs, 2020].
Does Linux have the same issue?
No. The Linux kernel bundles ICH7 USB modules since version 2.6.11, so input works out-of-box [Kernel Changelog, 2005].
