Lynx Point USB 3.0 Controller Issue Correction Needs New Hardware

The issue with USB 3.0 controllers integrated into Intel's upcoming "Lynx Point" 8-series core logic can be addressed only with new hardware (modifying the silicon), according to a new Hardware.info report. Intel decided against delaying launch of the 4th generation Core "Haswell" family to address the issue, and instead opted to address it in a future revision of the chipset.

A design flaw causes devices connected to Lynx Point's integrated USB 3.0 controller to be disconnected when the system wakes up from S3 (suspend-to-RAM), forcing users to reconnect them. This could mean you'd have to mount your USB 3.0 hard-drives/flash-drives again, although no data is lost. If you're editing files stores on such a storage device, you might have to save your work before the system is put to S3 sleep.

In 2011, Intel launched its 6-series "Cougar Point" core logic that drove its first LGA1155 processors based on the "Sandy Bridge" architecture; with a faulty SATA 3 Gb/s controller, that warranted a general recall and replacement with 6-series Rev 3.0 chipset. This particular issue is classified by Intel as more of an irritant than a major flaw. It remains to be seen how it affects early adoption of the platform.Source: Hardware.info

1. its a default feature of windows, enabled by default. this WILL affect many people.

2. i have 18TB of external storage. no way in hell would i unplug each drive and replug after S3 sleep.

3. S1 is standby (monitor and hard drives off. everything else on). . S3 is sleep mode. S4 is hibernate. (most BIOS only let you choose S1 or S3)

4. doubt it. how would you 'safely reconnect' it?


the worst part is that this might get mentioned in a motherboard manual at best. this bug will not be listed on mobo boxes, nor will users buying prebuilts be notified of "oh yeah, the USB 3.0 ports are glitchy"
Yeah i didn't think about reconnecting it.
and dang 18TB of storage! I can fit every data i own on 600GB. Is your 18TB on USB 3.0? if not then you don't have a problem.

I wonder if you have a device that's 2.0 plugged into a 3.0 plug is it effected? or is it everything is affected.

anything on the usb 3.0 ports would be affected.

so again the question is, is it the the usb3.0 controller/chipset thats faulty? or the sleep states on the haswell chip thats faulty? in other words, would motherboards use third party usb3.0 controllers fix this problem? or is that not possible?

if it used third party USB Controllers, those ports would not suffer from the issue.

this is specifically related to the built in USB 3 ports of the intel chipset.
