Still good!
 

Hi TBM,

Had 2 full days in a row without any black-out while using my laptop normal or even beyond normal memory wise.
This is a record for sure!

Hope this continues the next couple of days.
Keep you posted.

Hi Ruud,

Good to hear you're still good :)

If possible; can you also try to sometimes transfer large files using the dock's Ethernet port from your laptop while you're working to (if you have) a local server? To get the maximum speed, for instance take a 4GB dummy file.

I've never experienced a stable Ethernet connection. The transfers didn't complete.. While the black-out occurs the Ethernet connection was also reset... and the mapped network drives became unreachable... Very annoying... :(

4 days in a row!
 

Hi TBM,

Still haven't got any black-outs since I switched to the right side USB port.

Feels kind of stupid I didn't try that option before.. could have saved me countless numbers of reboots and general agony.

I will try a good file download if I can get my hands on any decent size file (much look one up, that's all)

Thanks for asking,
Ruud

Not stupid! Because we bought 2 USB3.0 ports, and now the left one doesn't have the USB3.0 specs.

You can download test files from: ftp://ftp.surfnet.nl/pub/test/

I hope you can continue working without any blackout...

Groeten,
TBM

Did network copy test..
 

Hi TBM, downloaded the 10GB test file and copied it over the network (1Gbit) to another server: it worked.
In the beginning fairly constant, but then on and off, on being around 60MB/sec max, off: 2 - 3 MB/sec. It sort of looked like it was choking on the line or something.

Great that even while transferring 10GB files you still haven't had any black-out! Hoeraaaaaay!

Well now we can confirm that the left usb port is the issue for all of this...

Unfortunately i can't test it with my own dock (the second one from DELL) isn't functioning anymore... Only had it running for 3-4 days and when i've powered on my laptop on day 5 it wasn't recognized by Windows. I even can't get it to work on a fresh clean installed Windows 8 system....

I've called DELL for a solution for my problem, but still no answer.... :confused: :mad:

XPS13 USB HS Port Not Docking
 

USB 3.0 Super Speed (right side of the XPS13) is best. The dock should work on both the left side USB2.0 port and the right side USB3.0 port.

However, the latest FrescoLogic Host Controller driver version 3.5.100.0 seems very stable for USB3.0 in the right side SS port, but the HS port on the left seems to have gone incompatible for docking on the Dell XPS13 LS321 with Targus dock ACP71. The Device Manager shows a yellow bang on the USB hub from the dock as if they are incompatible. The XPS13 LS321 does dock with the Targus ACP70. They do have two different USB hubs chips and I will check with the vendors to determine compatibility issues.

Does is appear the same with the Dell XPS LS322 containing the Intel USB Host Controller?

@Ruud

And? No more black-outs since you've switched?

Dell XPS 13 (L322X)
Intel USB 3.0 chipset
Kensington SD3500V
Anker USB 3.0 Dual Video

Left USB 3.0 superspeed powershare has had problems with the displaylink docks with the provided USB 3.0 cables between the laptop and displaylink dock

Right USB 3.0 superspeed has performed much better wit the displaylink docks and the provided USB 3.0 cables between the laptop and displaylink dock

Currently I am testing a theory by using a USB 2.0 A male to B male with dual ferrite cores between the laptop and displaylink dock. I am waiting to see a failure so I can collect logs and see if support sees the same USB errors they were seeing when I was using the USB 3.0 cable.

Update
USB 2.0 cable did do better. Eventually I hit the possible memory leak issue. At least the support items I submitted did no show USB errors according to the displaylink support. Makes me wonder about that USB daughterboard and the cable that connects it to the motherboard. I haven't cracked it open yet to see what kind of cabling they used.

@longplaypg

Thanks for the info, and testing! :)

Today i've received my third Dell D3000 dockingstation. Now running for 3 hours on the RIGHT USB port and a clean Windows 8 installation with the lastest USB/DisplayLink drivers.

In this stage i haven't experienced any black-out...... (yet)

Working on the laptop, and extended the display via HDMI to my TV, playing videos with VLC :cool:

I think i'm getting an longer USB3.0 cable to connect to dock with the laptop. Because the length of the original cable is wayyyyyyyyy too short :mad:

Or is the provided USB3.0 cable something special??

Still no black-out!
 

Hi all,

I just want to say that I did not have any black-out since starting to use the right USB port..

:):)

From my experience I have 2 USB 3.0 cables.

One that is clearly marked e301195, super high speed, USB revision 3.0, with the proper USB 3.0 connectors and thicker cable. Waiting on confirmation no USB errors in debug logs, but works the best to me.

One that is not marked at all, with the proper USB 3.0 connectors, and a thinner cable. Thinking this one may not be full USB 3.0 support and causing some USB errors in support logs.

I was thinking about testing with a 3rd cable that is longer with dual ferrite cores, labeled for USB 3.0 super speed, and proper USB 3.0 connectors. I just haven't bought one yet.

Ok good, i've just transferred the 10GB test file mentioned earlier, and after receiving 577 MB @ 15.0MB/s the network connection was lost! Pulling the USB connector didn't work... No Display/LAN....

So i had to remove the power from the dock and rebooted the machine, and all was working again...

@Ruud
Try to transfer large files via LAN, using the highest speed possible.... I will try it too later tonight to see what happens...

Please understand I have the following hardware which is probably different from yours.

• Dell XPS 13 L322x
• Kensington SD3500v
• Windows 7 Enterprise 64 bit host

Using right USB 3.0 port without powershare with the Ethernet connected to the docking station

• First snapshot shows the transferred 10gig file from win8 RDP back to win7 host SSD hdd through terminal service share
• Second snapshot shows the complete desktop with multiple RDP sessions and a transfer going from the win7 ssd through terminal share back to the win8 hdd
• Third snapshot shows the near final transfer speeds. I got interrupted and had to take the snapshot a little early. Both transfers did complete fully and I never got black screens or lost my Ethernet.

Does your USB 3.0 cable have any writing on it?
Does it have the blue USB 3.0 connectors (especially that new B male one)?

@longplaypg

Thanks for the info!

My configuration is:
- Dell XPS 13 L322X
- DELL D3000 Docking
- Windows 8 Enterprise 64-bits

I've looked at the cable and the writing on it says:
AWM E89980-A STYLE 2725 80C 30V VW-1 28AWG/2P+1P 26AWG/2C SUPER HIGH SPEED USB Revision 3.0

Both connectors are the BLUE ones, and on the connector i see the SS for Super Speed.

At this point i haven't had any black-outs, using the RIGHT USB port. The first black-out i've reported was due to network configuration changes i think. I'm doing stress tests to see if i can force an black-out :D No luck so far, so that's good :p:D

Seems that if i stream music and download files the network speed becomes slower than normal. If i stop streaming music the download will go much faster. The streaming is only on 128kbps... Guess this is normal?

Is it possible for you to test the transfer speed using USB3.0 harddisk or USB-stick on the LEFT USB port? Too bad i've bought an XPS 13 with only ONE USB3.0 port...

BTW: I have USB PowerShare ON!

I haven't actually tried any audio or video streaming yet

Sorry I no longer have these 2 laptops in my possession currently. I might have access to 1 of them in a couple weeks and I will ask the end use if I can borrow it again.

I know what you mean. That left port is labeled as SS 3.0 with powershare, but sure doesn't seem to be a full SS 3.0 even.

Now updating the drivers version 7.4 M2, released 11 Oct 2013 to test the ethernet improvements... Later this week i'll test the longer USB3.0 SS cable...

The left USB port is functioning as USB3.0 BUT when i transfer large files >4GB Windows keeps informing about a new detected USB device, so the connection to the USB drive gets lost and it reconnects again, but serveral times... Very strange...

So far no black-outs occured using the RIGHT USB-port...

Hello folks!

I've been lurking these forums for several weeks and am recognizing many of the same issues to those that own the Dell XPS's and the Targus Docking station.

I work in a medium sized business and we will eventually have about 60-70 people here at corporate with this set up.

I really just want to thank those who figured out to use the right USB port on the XPS rather than the left. Such a simple fix yet genius in the same. Changing my users over the right has made a lot of people happy. We are 1 week in so far and we've had no problems!

I have updated intel usb 3 for xps (maybe other computers) drivers.

Read all steps before doing!

Directions:

1) download
2) unzip files
3) start run type this: shutdown.exe /r /o /f /t 00
4) select troubleshoot
5) select boot options
7) choose 7 " disable signed drivers..."
8) right click on intel usb 3 extensible host then properties
9) update driver (browse --> let me pick from a list... --> have disk)and choose point to the location of where you unzipped the attachment pick iusb3xhc.inf then choose intel usb 3 extensible
10) you will then see another unknown driver in device manager
11) update that driver using the files in the zip but pick iusb3hub.inf *usb 3 hub*

You can try these drivers out without the above steps, just update the driver using normal mode. Let me know if this works.

For Intel x64 usb3 windows 8.1

My first assumption is this driver is only for window 8.1. The changes you made are not applied if installed under windows 7 x64. Is that correct?

I went ahead and modified my package install so that it uses these drivers and I still have black screens and disconnects on the left port. I did see the warning about installing an unsigned driver so I feel like the new driver was used.
