Dell XPS USB 3.0 Issues

I am having random disconnection issues with the 2 USB 3.0 ports on my newly purchased XPS L702X.
It is completely unrelated to the device and occurs at no specific interval and is only recoverable with a reboot.
Based on a Dell Support Forum - XPS 15 - USB 3.0 Problems, this issue has existed since the 1st generation release late 2010 of the current XPS series and appears to affect many users.
Based on feedback, consumers who contact Dell for resolution end up with no resolution despite motherboard/daughterboard replacements.
Also, a Renesas controller driver upgrade or rollback does not cure the issue either.

I am starting this discussion to find others who have encountered this issue as well and have either found a resolution to actually using the 3.0 ports or who may have not yet spoken up... This issue has gone on far too long without resolution and in order to get Dell to take this defect seriously, everyone affected needs to read the forum and take part in the descussion,
Please post any information you have... even if you have an XPS Laptop current model 1st and 2nd generation without 3.0 issues... you too can help find the solution.

Thanks

I've seen this happen for years with no "one thing" being the cause. I have run into folk that think it's a driver or the maker but let me share I have ZERO PROBLEMS with this today.

However I know to look at the various control panels to remove, uncheck power saver settings, change the drive to not spin down (if that's what I want) and a few other things.

Sadly, I've never found it to be one thing. One time it was the same old USB power issue. That is, using a wall wart to power the drive fixed it.

Then again, I run into folk that want Dell to fix it so the wall wart is not required.

Bob,
What model XPS are you running?
What Renesas driver version/firmare version are you on?
Also if you can list all the settings you changed to get to zero problems, that would be great.... would help the rest of us possibly.

Many of us in the dell forum have already tried setting all the power options etc. that we are aware of as well as a few "suggestions" from Dell.
The issue occurs when you use anything that cannot be powered by a wall wart... ie. mouse, controllers, modems, keyboards, you name it.
A few have reported issues even with powered 3.0 hubs with multiple drives attached... they were unable to use the hubs and had to go with only a single ext. drive per port and depending on the drive used, some still have issues as it appears a few drives will not work with the port.

Most everyone has no issue with the USB 2.0 or eSata/USB 2.0 combo port.

But I'm away from the office for a few weeks.

The drivers are whatever Dell supplied. At the office we never update or chase down new drivers.

But the fail to work USB 3.0 drives are returned as defective. Let the makers eat those.
We learned long ago Dell is not going to change their stuff with work with someone's drive. So we took the easy exit.

I'm sure folk wanted a better answer and for that I apologize.
