USB Hub in Dell U3011 not working over Mini-DisplayPort(Thunderbolt) when it did with previous MBP

My previous MBP, a few years ago - the first generation with Thunderbolt - was able to generate a USB connection over Mini-DisplayPort with my Dell U3011. My late 2013 MBP is able to send display and audio, but seems unable to detect the USB hub in the monitor. I am on 10.9.4. Any thoughts or suggestions?

I turns out that the logic board of my MacBook Pro was faulty (despite being brand new).
I took it to the Apple Store, presented the problem, and one of the Tech's came to the same conclusion that I had -- hardware failure. Phone support was no help in the matter (and even told me that what I was trying to do wasn't a supported option, which is rediculous). However, the Genius Bar did take care of the problem, and my MacBook Pro was back to me with a replaced logic board within a few days.
Hope that htis helps.

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine

Mini-Displayport to DVI adapter not working, but Mini-Displayport to VGA and Thunderbolt work fine.
This is a brand new MacBook Pro (15-inch, mid-2012) just received. I suspect that this is a hardware problem as:
The mini-displayport to DVI adapter and the external monitor that I am utilizing connect and operate just fine using my older MacBook Pro (mid-2010) with the same OS.
The new MacBook Pro powers the external monitor with a mini-displayport to VGA adapater without issue.
The new MacBook Pro powers an Apple Thunderbolt display without issue.
Both MacBook Pro's are running OSX Lion 10.7.4.
The only combination which does not work is the mini-displayport to DVI adapater used in conjunction with the brand new MacBook Pro (mid-2012).
All adapters and components (mini-displayport adapters) are Apple retail adapter.
I have tried several external monitors, including my Dell U2412m.
When I connect the mini-displayport to DVI adapater to the new MacBook Pro (mid-2012), nothing happens. The external monitor reports "no signal" and attempts to go into sleep mode. Using the "Detect displays" button has no effect, even when used multiple times. Rebooting does not help, nor does resetting the SMC or PRAM.
Any other suggestions before I take it to the Genius Bar?

The BlackBerry servers in Europe have been experiencing some problems over the last couple of days. That's why you've been unable to connect to any of the BlackBerry services.
Glad I could clear things up for you.

Till my last software update on my MacBook Air I have been able to use my iPhone as a modem via USB. Now it's not working anymore. Other functions via USB are still fine. Any ideas???

Till my last software update on my MacBook Air I have been able to use my iPhone as a modem via USB. Now it's not working anymore. Other functions via USB are still fine. Any ideas???

The Mac was recently upgraded so it is the Mac, or is it?
Looking for a common denominator: I'l start with wi-fi as the common communication medium.
Known:
A) Broken: iPhone —> wi-fi —> Mac.
B) Broken: iPhone —>USB—> Mac.
C) Broken: iPhone —> Bluetooth —> Mac.
D) Working: Mac —> USB —> other USB devices.
Unknowns:
E) Test Mac —> wi-fi —> a non-iPhone router.
F) Test iPhone —> wi-fi —> another wi-fi device.
Given not A, not B and not C either the Mac or the iPhone could be the culprit.
1) E        | F        : Non sequitur (deepens the mystery).
2) not E | F        : The Mac is the common denominator.
3) E        | not F : The iPhone is the common denominator.
4) not E | not F : All heck broke loose.
For case 1: It would be something on the Mac that prevents it talking to the iPhone through three media even though it can talk to other routers over wi-fi. That would be weird indeed, given the iPhone is talking to other wi-fi devices with no trouble.
For case 2: All of the Mac’s intranet media broken (wi-fi, Bluetooth, and wired-USB) and at least wi-fi works on the iPhone. Something weird is going on in the Mac.
For case 3: The iPhone router function is broken. Upgrade the iOS? Test using another iPhone?
For case 4: Throw everything in the trash and start over.

How to delete video from iTunes library? del and shift+del are not working - no any reaction

Hi
Currently, iMatch is turned off on my computer, as I do not want to upload any more songs. If I turn it on, will it upload all songs that are currently in my library? Is there another way that deleting them one by one?
You must enable iTunes Match on the new computer. The best way to accomplish what you want to do is to create a new, empty library by launching iTunes while holding down the Option key (Shift on Windows) and choosing "new library." Do not let iTunes scan for new content, but do enable iTunes Match on the empty library. Once the scan is finished you may delete tracks from the cloud. When you are done switch back to the main iTunes library.

Windows reports that the "USB-IF xHCI USB Host Controller" device is not working properly.

I have been receiving the following error and instructions to fix it for a long time now, prior to updating to Windows 8.1:
A device is not working properly
Windows reports that the "USB-IF xHCI USB Host Controller" device is not working properly.
Recommended solution to the problemUse Windows Update to check whether new device drivers are available. Proceed as follows:
Open Device Manager
Search in the device manager for the device whose driver you would like to update and double-click on the device name. You may first have to enable the "Show hidden devices" entry in the "View" menu.
Switch to the Driver tab, click Update driver and follow the instructions
When I follow the instructions and try to update the driver, I am told "The best driver software for your device is already installed."
How do I update the driver to stop receiving the error?

My apple usb adapter for iPad dose not work any more

I use USB adapter before , but can not work any more

Can you try it with someone else's adaptor to make sure that is where the fault lies?
Make sure it is connected directly to the wall socket and not through a two way adaptor.
Move both ends of the cable slight to make sure there is not a loose connection.

Facebook App not working over 3G, but works over Wi-Fi.

I have a BlackBerry® Curve™ 3G 9330 Social Messaging Ready smartphone. My current software version is 6.0 Bundle 2333. My Facebook application worked perfectly fine when I got the phone a few months ago over the Verizon 3G network and Wi-Fi, but when I recently updated Facebook to version 2.0.0.58, it does not work over 3G anymore. But everytime I try to connect via 3G it says "We cannot reach the Facebook server at this time. Please try again later. (100)" It does however still work over Wi-Fi.
I have tried various attempts to fix it: uninstalling the App and re-installing it and also removing the battery and putting it back in (hard reset), but nothing has worked.
Is anyone else have this same issue? Is there a way to restore my Blackberry to its factory settings so that I can just use the older version of the Facebook App [that was previously installed]?
Thank you.

Hey metalhourse90,
I can see from your PIN that you currently don't have browsing services included in your data plan. I would advise contacting your wireless provider to have this enabled.
Thanks,

I recently moved my library on my time capsule
You mean you moved your music files to the external. The library is more than the music files.
Just copy the \Music\iTunes\ folder from internal to the Time Capsule.
Add the Time Capsule to your Login items in System prefs -> Accounts.
Hold Option and launch iTunes and select *Choose library*.
Select the iTunes library file int ehiTunes folder on the Time Capsule.
It is hte samae library you have previously. All artwork playlists, ratings, songs, movies, etc. will be there.
Genius is already there so nothing needs to be done.

Why does not ipad show on itunes? when i connected with my macbook using usb, just it is charging electricity.

why does not ipad show on itunes? when i connected with my macbook using usb, just it is charging electricity.
i don't know why...

Sometimes it can be something very simple and easy to fix. Before you get into any involved troubleshooting, quit iTunes, restart your Mac, restart your iPad and then try to sync again.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
If this doesn't work, then try the more involved stuff.

I guess I will wrap this up. I have abandoned iPhoto and viewing my Photo Streams using it and moved to Adobe products (Bridge + PS). So that's that.

Hmmmm... would appear that you need to be actually logged in to enable the additional menu features.
Have you tried deletting the plists for MAS?
This page might help you out...

Failing that, I will have to throw this back to the forum to see if anyone else can advise further.
