Bug 14524

This is repost from https://bugs.gentoo.org/show_bug.cgi?id=290429

I'm using AlcorMicro usb hub as an extension for keyboard and mouse. Kernel
does not detect keyboard during boot or then I connect hub with keyboard
attached ( I tried with/without mouse)
I have to unplug and plug keyboard back to the hub every time.
There is no such problem with mouse though. I tried it with Windows XP as well
and it worked fine.
Here is a log file with the problem and my action:
