commit f4d35d49e32c29183b3492da18ea480d91716efe
Using nativedisk or loading ohci for USB keyboard support when my Logitech
G510 gaming keyboard is plugged in causes some problem with the USB
subsystem.
Steps to reproduce, while G510 is plugged in:
> nativedisk
OR
> insmod ahci
> set prefix=(ahci3,msdos1)
> insmod ohci
The symptoms are that the G510 is not fully initialised (should display the
G510 logo on the built-in screen), the Grub does not accept input from the
keyboard, and Linux hangs on USB device discovery with repeated message:
usb 4-3: device descriptor read/64, error -110
My generic USB keyboard does function correctly after loading nativedisk or
ohci.
Boot eventually continues once the USB subsystem gives up on trying to
identify and enumerate the keyboard.
After rebooting, either warm or cold, BIOS POST also runs slowly. The only
remedy is to unplug the G510 or power off the PSU.
If Linux is booted using biosdisk (without loading ohci), or the keyboard is
unplugged on boot and plugged in after the kernel loads, then the G510
keyboard works correctly.
It may be worth noting that lsusb -v shows the G510 is a USB2.0 device, not
USB1.x as most keyboards are.
