Kensington USB 3 Super Speed Dock not functioning

I have a Kensington USB 3.0 Super Speed Dock connected via a USB cable to my 13" macbook air (purchased in January 2014). Mid2013, 1.7 GHZ. Intel core i7. 8 GB 1600 MHz DDR3. Intel HD Graphics 5000 1536 MB
Since upgrade to Yosemite the dock is not recognized by the macbook air.
I have a second monitor running through the dock and this monitor is not visible. I also have a backup drive hooked up through the dock and this does not function either since the upgrade to Yosemite.
I spoke with kensington and we upgraded the display link driver with no success.
Any thoughts on how to get my second monitor working? The first monitor is connected from DVI to thunderbolt port. The second monitor is connected from VGA to USB 3.0 to the kensington dock.

I've discovered it's not that USB 2.0 is not working. 3 out of 6 usb ports/busses seem to work properly. The other three seem totally dead. Obviously this was not the case under kernel 3.9.9-1. Downgrading to kernel 3.10.2 made no difference.
In practical terms this means that I can use my printer and access my external drive if I use the right port/bus. And I could probably work around the problem by plugging a USB hub in one of the working ports. But I would be happy to get rid of the error messages and have all 6 usb busses working as they did before...

My USB super drive is not reading DVD

External SuperDrive DVD player fix - RESOLVED!
This solution worked for my Superdrive, which I had installed in a USB external case, so now it can play movies using Apples DVD Player App, but additional steps may be needed, as I outline below. I had removed the SuperDrive from my mid-2009 Macbook Pro 15" 2.53 ghz to install a second hard drive with Other World Computing's "Data Doubler" adapter, and mounted the SuperDrive in an OWC Value Line SuperSlim external case.
I don't know if the first two steps below are necessary, but I had done them first, because others suggested them as fixes before I found the solution in the 3rd step.
1) I installed Apple's SuperDrive Firmware Update 3.0, which is on Apple's support site at http://support.apple.com/en-gb/HT201953
2) Then I applied a fix on this page, http://www.hardturm.ch/luz/2011/10/how-to-make-the-macbook-air-superdrive-work-w ith-any-mac/comment-page-12/#comment-106449, using Text Wrangler to edit the preference file at /Library/Preferences/SystemConfiguration/com.apple.Boot.plist by adding code mbasd=1 between the two string values. However, that still did not resolve the problem. I left the preference file with the code “mbasd=1″ included, as outlined on that site.
3) Then, I used the fix at http://macriot.com/mcrt/?p=2294 which requires modification of some code embedded into OS X’s DVDPlayback framework; essentially replacing the words “internal” with “external”
Now my external Superdrive plays movies using DVD Player.

My USB Super Drive will not Play Red Box DVDs, Why?

Can anyone explain why my USB super drive will not play RedBox DVDs?

What Mac are you using with the USB SuperDrive?
Is this USB SuperDrive a third party drive or Apple's USB SuperDrive?
If this optical drive is Apple's own external USB SuperDrive, this only works with newer Macs that have no built-in optical drive any longer and WILL NOT work with older Macs that came with built-in optical drives.
Is the Red Box DVD a standard DVD or Blu-Ray DVD disc?

USB Keyboard/Mouse do not function in Bios (Bios Change log too)

I have 1.7 and the system seems fairly stable, a few BSOD's occasionally and it normally seems to occur when the system is idle. I can work on that, but now when I boot my usb keyboard will not function for the EFI/Bios. I have a Old PS2 keyboard working for now but was hoping there is some work around that someone might now. Everything is enabled in the Bios and I even disabled, saved, re- enabled, saved.
Saving (F10) still causes the system to power down, but I can live with that.
Now for the BIOS, can we get a change log to determine what issues are being resolved with these update? I have 1.8b7 downloaded but last update I lost my Raid array so I want to see change logs before a possible rebuild.
Lastly I am used to new hardware having issues especially with OCing, but the EFI/BIOS seems extremely temperamental. First MSI board and my work is on the road a lot so I am hoping to get some of this fixed soon.
Thanks for any advice

USB 3.0 Dock not playing audio

I have an ASUS VivoBook running Windows 8 connected to a brand new Lenovo ThinkPad USB 3.0 Dock. I just ran the setup disk and installed all the drivers, but the audio is still defaulting through the laptop speakers and not the audio jack on the front of the dock.
I looked in the device manager and it shows that the Lenovo USB Audio has no driver installed. I selected Update Driver and did both the automatic check and browsed to the driver folders on both the install disk and in the Lenovo folder on the hard drive, but was unable to successfully install a driver.
I disabled and re-enabled it, I uninstalled and reinstalled, both were ineffective.
I updated the firmware on the dock and installed the latest drivers from the Lenovo site, but neither of those worked either.
This seems to be a rather uncommon issue, I have yet to find any reference to any others suffering this same problem. I am not sure if the problem is Windows 8, the Lenovo drivers, or if this driver is standard on Lenovo laptops only so not included in the driver packs....
I would greatly appreciate any help that can be rendered.
Thanks in advance.
Solved!
Go to Solution.

The USB audio driver for this dock should be installed when DisplayLink graphics software is installed. The latest version can be found on our website here:
http://www.displaylink.com/downloads
If you open up the Control Panel -> Sound and look at the playback devices, does the audio output appear in there? There is hot plug detection on the jack socket, so the audio can only be selected when headphones are plugged in.

HT2494 Usb super drive is not playing my dvds. keeps ejecting them. It is brand new

USB SUPER DRIVE IS NEW. MAC IS NEW. THE DRIVE IS NOT ACCEPTING MY DVDS. KEEPS EJECTING THEM.
I HAVE THE MAC, 21.5 INCH INTEL BASED DESK TOP

I have the same issue wherein my external usb superdrive is ejecting the DVDs.
When I had the Snow Leopard, I was able to copy the DVDs into my hard drive, or even just watch DVD films. Since I have the Mountain Lion, the DVD films which I used to be able to watch were not able to be read anymore ... it ejects them.
I did not notice it when I upgraded the Mountain Lion, because I did not watch any new DVDs. Noticed this only couple of months back, and been searching for the solution.

T440s Windows 8.1 Pro and USB 3.0 dock not recognising DVI LCD panel

Perhaps somebody could help me here.
When I connect the USB 3.0 dock to my T440s, I then cannot get the second LCD monitor to be recognised by Windows via the USB3.0.
The monitor is not being recognised as it is is not seen as one of the optional displays in the 'Intel HD Graphics control panel' window.
The driver however for the second monitor is fully up to date and it works fine when I connect the LCD to the VGA port directly on my computer. Also the second monitor is being recognised partly by the windows OS as it comes up as a second screen under the 'screen resolution' window.
My set up is shown below. I am thinking that perhaps there is an issue with either the NVIDIA or Intel HD graphics chip. I read somewhere that windows uses one or the other depending on the load. I am worried that there is some problem with that mechanism.
Can anyone help or give me some advice on this? All driver are up to date.

BUG: Speed Dials not functioning correctly when Option button is last used

There is a bug in WebOS where Speed Dials do not work correctly. Holding down your speed dial favorites button will not place the call. This happens when the option key is used in launcher or card view before attempting speed dial.
For instance if your last character of a search you did 4 hours ago on your phone contained a series of numbers and you locked the option key to do so, (or even if you accidently hit the option key last and then did not need it) then an attempt to use speed dial "G" will not work, as your Pre/Pixi thinks you are holding down the "6" key and not the "G" key.
This needs to be remedied (for instance have the option key press clear out or unlocked as soon as the search is performed or cleared off of the phone) because there is no way to tell what state the option key is in before using a speed dial (not that I want to check and fiddle with it anyway).

The Z and B keys are the * and # keys. That is why they are not in the speed dial list. Hmmm... while it might be a "bug" at this time your the only person having this issue as far as I can tell. Since the issue moved to another phone it could be that its related to your Palm Profile. I unfortunately cannot replicate this issue but would like to test something. Can you do a Partial erase on your device and create a new Palm profile? This will see if the issue is still on the device.
If it is not then the issue is within your Palm Profile. If that is the case I can help you from there. Please post back when you tried this step.

USB 3.0 Dock not identifying primary monitor at startup

I've seen an issue recently where the Thinkpad USB 3.0 dock has trouble recognizing an external display that is set as the pirmary monitor. In this scenario, the laptop display is being used as an extended display and an external monitor attached to the dock using DVI is set as the primary. Upon startup the Lenovo splash screen displays on the laptop monitor (this is normal) and then afterwards the laptop monitor displays a purple screen and the external monitor goes into power saving mode. A blank purple screen is what is displayed on all extended monitors when Windows 8.1 is at the lock screen, which itself displays on which ever monitor is the primary.
At this point you are unable to do anything since the lock screen cannot be seen, and are required to hard reboot. After hard rebooting the issue typically clears up. This issue is occurring aftering doing a proper shutdown in Windows 8.1. In the case the laptop is a Yoga 2 Pro but I have also seen it occur on a Lenovo X1 Carbon, which leads me to believe this is a dock/software issue.
Has anyone else experienced this?

Yes - did you ever find a solution? I tried updating the Displaylink driver.

K9N6PGM2-V, Win XP Pro/SP2, USB only works at USB-1 speed

Apologies is this is on an FAQ somewhere -- I did look, but didn't see it. Anyway, the USB ports work fine at USB-1 speed, but not at USB 2.0 speed. In fact, MS XP reports that there are no USB 2.0 devices available. Kinda frustrating, since the MSI manual specifically mentions USB 2.0 pin headers for this motherboard.
The PC (see signature) is built from scratch. At this point, the only software that is on it is XP Pro, SP2, and downloaded MSI drivers, and the only hardware added is the Intel Ethernet card. I installed the full package of drivers from this web page:
http://global.msi.eu/index.php?func=downloaddetail&type=driver&maincat_no=1&prod_no=1472
Specifically, I downloaded the full set ("NVIDIA_MCP61_SYSTEM_MB.zip") and installed everything except "forceware network access manager.".
One other note -- When I installed the motherboard, I connected the front panel USB connectors to the motherboard's JUSB1 connector (should I have hooked it to JUSB2?) ... however, the same behavior (USB1 speed only) happens with the built-in connectors (next to keyboard/mouse input, etc.)
Can anyone help? Thanks.

USB2 devices not functioning to USB2 speeds on K7N2 Delta-L

Dear all,
Before i get the "Use search" button, i have and done it practically all day trying to find a solution.
My system: MSI K7N2 Delta-L, running on Windows XP service pack 2
4 USB ports at back panel, 2 USB ports on the D-Bracket (where there is a High Speed sticker on it)
All USB ports front or back "work" but not any allow me to use a USB2 enabled device to make it function at its designated speed.
An example is: Transfer of a 20MB file takes 25seconds... ludicrous for a newly bought Kingston 1GB USB2 complaint flash drive.
I have read the stickys, i am certain the USBOC is not connected by any wiring, the manual in K7N2 already stated that, my BIOS is at the latest version, my system is functioning correctly, no IRA conflicts by checking through device manager.
http://www.apxc57.dsl.pipex.com/Connections.JPG
This shows that the USB2 Kingston device does not get routed to the Enhanced host controller, i do not know why, please let me know if you know!
http://www.apxc57.dsl.pipex.com/Front%20USB%20unplugged.JPG
A better view...
Standard Enhanced PCI to USB host controller - I'm not as certain to understand what this means. Does it mean that my board ONLY supports the Enhanced USB IF i purchase a PCI card that has USB2 ports on it??? And it means that ALL 6 of my ports onboard (including the D-bracket) are all Open HCD..........
I honestly have searched everywhere and there is NO definitive solution to this problem i'm having yet, MUCH MUCH appreciated if anyone can give a guiding light.....please !!!
THANKS VERY MUCH IN ADVANCE...

Interesting update... here:
I've been thinking about what everyone said here, so i was questioning whether this Kingston USB2 device is really USB2 standards.
Please take a look at here: http://scan.co.uk/Products/ProductInfo.asp?WebProductID=245123
That is the actual product and where i got it from, please just take a quick nip at the specifications.."Super Hi-Speed 24MB/sec"
As you know, i have the MSI D-Bracket 2, the exact image is found here: http://www.modsynergy.com/Modsynergy%20files/MSI-5.jpg
You can see from that image, that it clearly displays a "High speed, certified USB" from the red/blue logo.
A description that distinguishes between "High speed, certified USB" from "Certified USB" can be found here: http://www.everythingusb.com/usb2/faq.htm
Near to the lower end of the page.
Now... interestingly i now notice the back cover of the USB2 Kingston drive in which it was concealed in, take a look here:
http://www.apxc57.dsl.pipex.com/KINGSTON.jpg
Cast your attention to the Red Circle i have done. It doesn't say High speed certified, it just says Certified USB.
SO, let me quote from "What are USB Hi-Speed and USB Basic Speed logos? These logos are part of USB Promoter Group?s branding program that ensures the quality of USB products. The USB 2.0 certified products would display a blue, white and red logo, bearing the words ?Certified? and ?Hi-Speed.? The classic USB 1.1 certified products would display a black and white logo with the words ?USB? and Certified.?"
If my USB2 kingston device is really USB2 and support the 24Mb/sec transfer rate, the box should in fact have a high speed logo not a black/white one correct???
Thanks for reading, i'll get in touch with the supplier i think... probaly RMA come saturday.

I have an older iMac 5,1 and the disc drive no longer works. I was hoping that I could the Apple USB super drive as a replacement, but the info on the super drive page says compatible with iMac 2012 or later. Does anyone know why it would not work for me?

A reply to similar question (Q & As , in product page Apple Store) says:
"...dissable the internal reader hardware from devices setup. Then plug the external usb superdrive and that's it." Answered by Enrique T from Lima Oct 25 2013.
If you can locate an external Apple USB 'Air" superdrive for earlier model MacBook Air, that should work. The newer one for the Air is the same as for iMac, now.
You may be able to use other brands of external USB optical drive with your older intel-based iMac, as some of them function capably. A few should also be able to see system discs or other bootable utilities on DVD.
Hopefully this helps.
Good luck & happy computing!

How to replace the installed Generic USB Hub to Generic Super Speed 3.0 USB Hub?

Hi I have a problem with my RMBP 15" USB PORTS (both are 3.0 physically). Most of the days I will use windows 7 home premium through bootcamp.
When I connect my WD My Passport 3.0 to the usb port, there will always a pop up saying "Your device can work faster if it connects to a Super Speed 3.0 USB Port and when I do file tranferring between these 2 devices I will only get an average speed of 30 mb/sec which is DEFINITELY a speed of usb 2.0. As the usb 3.0 will be able to transfer (in reality) up to 100 mb/sec.
I think there is something wrong with the drivers installed. Attached is my device manager showing all the USB drivers installed.
Please advise me on what should I uninstall and install and where can I download the drivers or firmware.
For additional information, my macbook in using Intel Chipset C216.

This is more for googlers/random people in the same boat, since the OP may not be checking this any more.
I have arrived at this thread from another angle: I downloaded 'SlimDrivers', a free and non-contaminated 'driver updater' Windows program which is heavily-reviewed, on CNET as actually GOOD as opposed to almost all other 'dodgy' driver update checker programs out there (like Driver Reviver, Device Doctor, and Driver Detective - not to mention the scammy and notorious DriverAgent, of course).
I hit scan, and a whole set of drivers - seemingly under the one chipset download (as assisted by this youtube run-through) - came up. It's extremely user friendly and downloads the installer for you right from within the app. I've yet to install the chipset driver and restart - fingers crossed - but I think it's the same driver as OP is talking about.
Cos I've also noticed, at least once, some sort of USB issue in the past which made me think "huh, USB 3.0 mustn't be working with the bootcamp driver eh?"
So *I'm* wondering, whether what I've stumbled upon is indeed the same matter as OP, and thus also, maybe is a solution to the OP question as well .

I'm glad that keyboard and mouse are working properly under USB 1.0, but neither my usb-parport printer nor my USB external hard drive are recognised any more :-(
Any ideas how to solve this?? (I'd prefer not to downgrade the kernel)
Last edited by zilverling (2013-08-07 14:28:36)

I've discovered it's not that USB 2.0 is not working. 3 out of 6 usb ports/busses seem to work properly. The other three seem totally dead. Obviously this was not the case under kernel 3.9.9-1. Downgrading to kernel 3.10.2 made no difference.
In practical terms this means that I can use my printer and access my external drive if I use the right port/bus. And I could probably work around the problem by plugging a USB hub in one of the working ports. But I would be happy to get rid of the error messages and have all 6 usb busses working as they did before...
