Ok if no errors do you have any idea of the issue causing the problem in 13 and 14?

Kind of debunks my idea of the USB 3.0 only being able to handle 2.0 speeds only without transmission errors on that left port. Still odd if I put a 2.0 cable on that left port the unit runs just as well as it does on the right port with a 3.0 cable.

I am currently testing the 7.4 M2 driver on some outdated hardware. I have noticed my laptop stop updating all screens but the mouse is visible and moves. If I unplug the headphone and microphone connection on the displaylink device it releases and the screens update again. I am trying to locate some hardware that at least meets minimum requirements (ie video driver not outdated, wei score above 3.0) so that I can see if it is just this old laptop. If you want a displaylink support tool debug from this older hardware let me know. I doubt I will be able to start the debug tool while the screens are not updating, but I can at least start it after the screens start refreshing again.

Today I received the newer XPS 13 for a few days testing with the latest software.

1. Removed the Intel USB 3.0 Ex driver
2. Restarted
3. Removed the displaylink 7.4 M0 software
4. Restarted
5. Used the displaylink cleanup tool
6. Restarted
7. Installed the Intel USB 3.0 Ex driver 1.0.9.254 (was hoping a newer release, but not)
8. Restarted
9. Installed displaylink 7.4 M2
10. Waited a bit, but do not remember seeing the typical window that says my screen might go blank while it configures the screens.
11. Plugged into the left USB 3.0 with powershare
12. screens did go black but still don't remember seeing the warning window oh well
13. Configured the desktop layout
14. restart
15. Once the login screen displayed and displaylink displays were green light with black screens I closed the lid on the laptop
16. Started up the display link report tool
17. confirmed it was in advance mode and reset the debug logs
18. started 3 RDP sessions on the 2 displays and used them across the 2 displaylink displays
19. Main monitor had a RDP to 8.1 and Secondary had RDP to an XP machine all full screen on the individual monitors
20. The screens went black and the Ethernet on the displaylink device was disconnected.
21. Once I had a little control over the Main monitor minimized the RDP to see the contents of what was supposed to be displaying on the secondary monitor being displayed on the Main monitor.
22. Since I could reach the displaylink support tool icon on the taskbar I clicked it and started the gathering logs to hopefully collect information during the device issue
23. The screen shot was taken shortly after the display support tool started gathering. That araxis merge window was full screen on the RDP that has its RDP bar pinned on the second monitor in full screen view.

What caused this problem?

Hardware and Software

• DisplayLink 7.4 M2
• XPS 13 L322x
• Lid closed with laptop display off, but computer on and not sleeping
• Left USB 3.0 powershare to Kensington Sd3500v via USB 3.0 cable
• Kensington Sd3500v

• Headphone jack plugged in via headset
• Microphone jack plugged in via headset
• Usb 2.0 port plugged into logitech HD 720p usb webcam
• Ethernet plugged into 1G switch
• DVI to VGA adapter

• VGA adapter to main monitor via vga cable
• HDMI to DVI adapter

• Dvi adapter to secondary monitor via hdmi cable
• power adapter plugged in
• Usb 2.0 port plugged into main monitor USB

• dell usb keyboard via main monitor usb
• dell usb mouse via main monitor usb

Well that was a short period before the next mess up.

1. Shutdown computer with lid closed.
2. Open lid and power on laptop
3. Leave the laptop display open and use all 3 screens
4. Start display support tool
5. reset debug logs
6. Start RDP to 8.1 machine full screen on main monitor
7. Change RDP to window so I can drag it from Main monitor to secondary
8. Try to drag it from laptop main monitor to secondary displaylink display
9. Black screen and Ethernet disconnect BLAH
10. Gather logs and take screenshot

Well that's enough on the left port for today. What caused this issue according to the logs?

Hardware and software the same as in the previous post #18. The only exception this time is the lid was open and all 3 screens were active.

Bumping this back up also. Still would love to figure out why this hardware does not work on the left USB port of the XPS 13. I wish could read the contents of these reports to know if it is getting USB errors.

Thanks,

Interesting discovery. I see its more for the developer edition with Linux on it. Too bad Dell doesn't want to admit there is a problem yet. Sure would love to know how to get that port into debug mode.
