I'm getting this message since windows 8.1 release : "A timeout occurred while waiting for the EHCI host controller Interrupt on Async Advance Doorbell response." It only appears when my usb wifi dongle is under load. And it's not "heavy" load, just a new few tens of connections. So I've been researching this issue for years now and I've found and official statement from Microsoft that "some AMD chipsets do have this issue, AMD confirms". I haven't found any solution yet and I'm hoping to hear some from the "officials" or someone who could solve it. ASROCK Extreme 3 FX 990. Thanks.
