Sometimes none of my USB devices work. In device manager among the USB Controllers there are 2 controllers.
Intel(R) Series/C200 Series Chipset Family USB Enhanced Host Controller - 1C2D
Intel(R) Series/C200 Series Chipset Family USB Enhanced Host Controller - 1C26
When the devices don't work there's a yellow triangle for at least 1 of the 2. It seems to happen pretty randomly, and it's also random which one it is.
It's not like it suddenly crashes or something, if it works it stays working until after a reboot. After a boot it's hit or miss if it works or not.
Disabling and enabling the device again usually fixes it but sometimes you have to try a couple of times.
Under windows cp and rp the sound used to hang/stutter for a second when connecting a new device when the controller was down, which lets me think it's chipset related.
The issue is there at least since consumer preview, although it might have been there earlier (I don't remember).
Core i5 2410M
I think a HM65 chipset.
Laptop model is Asus k73sv.
I've heard that others with a HM65 don't have the problem, however someone with a k93sv model notebook also has the same problem. I guess it's something particular to this asus line? Maybe something with the mainboard...
