The thing keeps disconnecting and reconnecting every 5 seconds
 

Hello
I just got my displaylink thingie and it worked for the first time but after a
while when i got back to my computer i noticed that all my screens are flickering
so i opened the display details in win7 to show me how many screens are
connected and the thing keeps disconnecting and reconnecting about every
5 seconds non stop.

I tried installing the latest driver and nothing.

Tried disconnecting the unit from the usb socket and reconnecting and still nothing...

Any ideas?

Thanks,
Roi.

Anyone?
bumping...

If it is the USB that keeps connecting/disconnecting, this can be due to a lack of USB power. Is it connected directly to the PC? and the PC is not on battery?

Thanks alot guys, for some reason it works now without me doing anything special...I hope it stay this way...
Thanks alot.

I highly doubt it, you would be the first one to have solved this USB issue

Well, It isn't solved :(
The thing keeps connecting and disconnecting every 3 seconds and never
stops...
The green light turns on for a few seconds and then back off...

It's not a laptop, tried a few different USB ports (not on a USB hub, straight
to the computer).

What is up with that?

JamesH, I did this and sent you the file for this exact same issue, I never heard from you since. The file is here:
http://www.displaylink.org/forum/sho...85&postcount=9

This needs to be fixed as I am having the exact same problem on 4 different Surface 2 Pros. Never had a problem with this on Windows 8. Only on Windows 8.1. You are not alone rg12 :(

I also faced this problem. Your guide really helped me to solve this issue. Thanks for sharing this link.

Hi,

I need the logs from this tool to investigate your issue.

Thanks - I raised this issue internally when you provided the logs.

I'm now asking for an update on this. Apologies for the delay.

In Device Manager, with the dock attached, try disabling the ability on each of the USB Root Hubs for Windows to disable the device in order to save power, restart the system and see if the problem still occurs.

Also having issue
 

I'm appear to be having the same issue.

Windows 8.1; All Driver updates.
Using a pair of dell 2340t monitor Daisy Chained to my Dell Laptop via usb 3.0 port.

Dual monitors reset, renegotiate, and re-display. usually re-homing my apps onto my laptop display.

The only resolve I have is to unplug one of the monitors.

I do not have this issue on non-windows 8.1 Systems. Mac, Windows 8, win7 all work fine.

I have tried all different driver versions, I have used the display link driver cleaner, I have tried with disabling usb power saving.

I can private message you a dump of the tool if you'd like

Hi,

Thanks for the logs.

Does this happen on all the notebooks USB ports?

James

Yes, I have two USB ports on the dell, experience the same issue on both.

Didn't have any problem before I upgraded to windows 8.1, even with a clean install of windows 8.1.
Windows 8.0 had no issues.
My MacBook air has no issues.

Hi,

Thanks - have raised this internally.

Will get back to you when I know more.

Thanks,

Have you tried disabling selective suspend?

Can you follow the instructions here:

http://blogs.msdn.com/b/usbcoreblog/...ost-title.aspx

and see if it helps?

Similar problem on my Sony Multi-Flip 13A. Windows 8.1 seems to hate DisplayLink. I might get a lucky boot, where it runs fine for hours, but most of the time I get constant video resets/redetects every time I open, close, minimise, maximise or switch an application. Very frustrating! Log/data files sent.

I did a troubleshooting testing in various power plans; balanced, high performance, and Power Saver.

High Performance power plan has "selective suspend" disabled while plugged in, I experience the same issue while in this configuration.

this is completely inline with what I'm seeing.

Additionally, I thought the issue might be related to the new screen scaling capabilities in windows 8.1 so I tried the "Let me choose one scaling level for all my displays" option in hopes to remove that.
This did not help.

It sounds very much like there was something new introduced in Windows 8.1 that's not playing nicely with the earlier driver - maybe in the way memory is managed or something.

EDIT: James at DisplayLink suggested trying a USB hub, which has given me some limited success. Not a long term solution, but worth a try.

I got mine resolved, it's power too low, use USB Y cable to boost power.
 

I have the same problem, windows 10, toshiba AMD A8 4500, USB 3.0 is using AMD USB 3.0 eXtensible Host Controller 0.96 by Microsoft. Turned off all power management still didn't work. My USB 2.0 works though, so that means displaylink driver is installed fine.

Amazon reviews that are mostly positive but those are mostly mac users, but why it works for them? Probably because USB-C supplies 1.5A to 3.0A. So as suggested by displaylink support suggested to use Y cable. Ordered an external USB hub with power supply, plus a Y USB 3.0 with 2 male to 1 female cable. Plug the 2 into the hub, plug the displaylink 3.0 to the female and low and behold, works !!!!

so check your device USB 3.0 controller Event, if you see device migrated, device installed, device not started, it could be that it just doesn't have enough power when a certain rendering is needed, so it went off, came back on and windows thinks it is plugged in and detected a "migration" and installed again, then it's likely not enough power supply on the USB 3.0 port.
