Solved MacBook Air - Bootcamp - USB drivers have gone screwy

Hey guys,

I bought a MacBook Air a few months ago to run as a Windows only laptop, and so far it's gone great. But for some reason in the past few days my USB2.0 port has stopped reading devices, despite the fact that it charges microUSB phones and reads everything fine when I boot into MacOSX. My trackpad drivers have also been screwy, and I think that has something to do with the USB hub.

Here's what device manager says:

Two Standard Enhanced PCI to USB Host Controllers give the error:

"This device cannot start. (Code 10)

Windows did not start a related device driver. To learn more, click the Driver tab and then click Driver Details."

One Standard OpenHCD USB Host Controller gives the error:

"This device cannot start. (Code 10)

Windows did not start a related device driver. To learn more, click the Driver tab and then click Driver Details."

Anyway, if anybody could help me out and help me to troubleshoot this it'd be really good - not having a USB 2.0 port makes file transfers take a few hours and my trackpad isn't working right.

Thanks,

Matt

There are alot of issues with Bootcamp. Signs like this means your hard drive is corrupted. I knwo what people are going to say "home do you know this." i have seen many mac start acting like this and a few sas later they can even boot in.

Okay... Well, is there anything I can do to try and get the USB drivers working again short of reinstalling Windows?

1. Do you have lion? Make sure bootcamp is upto date.

2. Bootcamp drivers are from when bootcamp is setup. When you install Windows using boot camp the drivers are downloaded for it.

Also, if you want a Windows only setup you do not need to use bootcamp.

Just in case anyone googles this, I asked in another forum and the issue had to do with the way Windows 7 SP1 deals with USB 2.0 drivers.

The solution was to uninstall the USB control hubs from device manager, restart, and Windows re-installed the devices automatically. Fixed.
