Did you ever get a response to this?  I have the exact same problem.  Bought the U2713H five months ago and the USB connection appears to have failed.  It used to work, but now there's no USB connection at all.  I've tried on 3 different computers with no luck.  This basically kills the whole monitor for me since there's no way to run the calibration software without the USB connection.  This seems to be a common problem.

Any response from Dell would be much appreciated.

Did you both try this?

* Turn off the computer and the monitor
* Disconnect all cabling from the monitor back and side (AC power, DC power, Audio, DP, DVI, HDMI, DP out, USB Upstream, USB Downstream)
* Press and hold in the monitor power button in for 10 seconds
* Reconnect the cabling to the monitor
* Turn on the monitor, then the computer. Retest

Note - The card reader is not supported in Windows 8 or 8.1.

Hi Chirs, 

Thank you for your reply. 

Yes, I tried this.

I´m using windows 7

Chris,

Thank you for your response.

Yes, I tried disconnecting all cables, holding power button for >10 seconds, reconnecting and powering up as you suggest.  I also left all cabling disconnected for 24hrs just to be extra sure.  I also checked the power saver settings to disable USB control from power manager and from within each individual USB item under device manager.  I have uninstalled and reinstalled all USB drivers, the monitor driver, Display Manager, and the Xrite calibration software.

I'm on Windows 7.  I tried other USB2 and USB3 ports on my computer and none of them recognize the monitor.  All of them recognize other USB devices.  I tried two other Win 7 computers with the same result.  I also tried a mac and a linux computer just to make sure.  All with the same result - no USB.  There is power on the USB ports, the xrite device flashes and my phone shows charging mode but no data connection.

USB worked the last time I calibrated the monitor 1 month ago.  Nothing has been plugged into the monitor USB ports since then, until I plugged in the xtrite device to run calibration yesterday and found that it didn't work.  Not sure if it matters, but I did a factory reset from the monitor touch panel before trying to calibrate (wish I hadn't done that now, since it wiped out my previous calibration settings).

Do you have any other suggestions?  I'm willing to try anything if it gets calibration capability back.

Since your monitor has a Dell Service Tag number, contact Dell Technical Support for your country. Provide to them the following data so they can setup a like for like monitor exchange =
Email Address:
Name:
Shipping Address:
Phone number:
Dell monitor (27" or 30") Service Tag number:
Dell monitor 20 digit alphanumeric PPID serial number:
Reason: Card Reader Failure
Note: Once outside of the initial 30 days from the original invoice date, the replacement will be a refurbished/used monitor

So, after only 9 months after getting a replacement for USB failure, the USB has now failed again.  I have used the USB connection exactly 5 times, all for calibration with Xrite.  Nothing else has been plugged into the USB ports.

Two questions:

1) For $1000 why can't Dell produce a product with reliable USB, especially when the high cost is driven by hardware calibration that can only be accomplished through the USB connection?

2) What now?  Try for another replacement?  Any chance you can just give me my money back so I can use it to buy a product that works?

Thank you

You cannot get a refund. Have you tested both the bottom and the side USB downstream ports? Have you taken the monitor to a different computer and tested both the bottom and the side USB downstream ports?

Before getting another monitor exchange, I would have Technical Support SHO (short order) you another USB Upstream cable, part number P57VD. Then retest using the replacement cable. If still no go, then initiate another monitor exchange.

Chris,

Thank you for your reply.  Yes I tried the bottom and side ports without success, and another computer, and unplugging everything and holding down power for 30 seconds, and the other potential fixes that I still had written down from the last time this happened.  I have tried another cable as well, without success.

I guess I will request another exchange and hope for the best.  

Chris,  

Can you please point me in the direction of someone who can help address this problem?

The Dell website won't allow me to email technical support because it says my service tag doesn't match my country.  Possibly because this is a replacement monitor?  It refuses to recognize the service tag or express service code, even though the product support website for drivers and downloads finds both with no problem.

I tried technical support chat, but they said they couldn't access my account and told me to call customer service.

When I called customer service the computerized phone system said my service code didn't exist.  I was then passed around to half a dozen different customer support reps, none of whom seemed to even know what a U2713H monitor was, or what a USB hub is.  They eventually transferred me back to the computerized phone system which asked for my service code and then told me again that it doesn't exist.

Needless to say, this has been a frustrating experience.  Is there a way to contact someone at Dell that can help?

Thanks

Call Order Support 800-624-9897. Give them the original Dell Order number. Using that, they will find your account. Then, provide to them the original U2713H service tag number and the replacement U2713H service tag number. Tell them to issue a monitor exchange off of the original Dell Order number.
