Problem with USB 3.0 ASMedia Host controller and DisplayLink

rlane00 · 02-27-2012, 03:14 PM

My laptop does have USB 3.0 (2 ports) plus a single USB 2.0 port as well. So far I've only been trying to work with the 3.0 ports - since the Targus universal docking station also supports 3.0.

I was able to update my driver (to ASMedia version 1.14.3.0), but the docking station is still not recognized on either of the (2) USB 3.0 ports. However, when I switched to the USB 2.0 port on my laptop the docking station sprang to life and appears to be working fine.

So it is now working - but would be nice to have the 3.0 operational as well. Any further thoughts on that?

At least it is now working on USB 2.0. We are aware of some issues with compatibility with DisplayLink and ASMedia USB 3.0 controllers. V6.1 M2 was specifically released to work around issues with this Host controller (ASMedia limitations, not DisplayLink problems). However the latest released version of ASMedia you have does not contain fixes that they have done, so there are still ASMedia problems with DisplayLink, that they need to fix. We believe they are working on these, but we don't know if/when these will be released.

I think it would be best to contact the laptop manufacturer and ask if there is an updated ASMedia driver to solve the compatibility with DisplayLink. We will also follow up with ASMedia.

Thanks

Hi,

To help us investigate this issue can you try version 1.14.4.0 of the ASMedia driver to see if that helps and also please post the logs that can be gathered through the tool described here: http://www.displaylink.com/support/ticket.php?id=269

Thanks
James

I installed the 1.14.4.0 driver (I hope it was done correctly). I then restarted the computer and connected to the USB3.0 port on my laptop. The behavior appeared to be the same as before on the 3.0 port - essentially the universal docking station was not recognized at all.

I then reconnected to the usb2.0 port and it's working again.

I then downloaded your debug tool and ran it (when connected to the 2.0 port) and attached the zip file that was created.

Hi,

The logs show that version 1.14.3.0 of the ASMedia driver is installed.

Did you try an upgrade to 1.14.4.0?

Can you try uninstalling 1.14.3.0 and then installing 1.14.4.0 and then see if the problem still occurs?

Thanks,
James

I am not sure if I can uninstall the 1.14.3.0 driver, and then reinstall the 1.14.4.0 driver. The reason is that the install for the 1.14.3.0 driver went very smoothly and automatically (like I suppose it should), however the install for the 1.14.4.0 did not go so automatically. I was able to download the 1.14.4.0 driver to my computer, but the "setup" program didn't automatically install the driver. Instead, I had to go to the device manager and update the driver for the ASMedia XHCI Controller manually. When I check the properties of that driver it shows me 1.14.4.0 (see screen shot attached) - so I presumed it was loaded.

Because the driver did not load smoothly / automatically I chatted with Samsung support about the issue. They said that they show the latest supported driver is 1.14.3.0. When I showed them the link to the 1.14.4.0 version the support guy just repeated the company line that 1.14.3.0 was latest version supported.

Any suggestions on how to proceed?

I have the same problem, My laptop Asus N55SF have USB 3.0 (2 ports) and USB 2.0 (2 ports also). My Targus are ACP70USZ and supports USB 3.0 but only works in USB 2.0 the driver of DisplayLink Graphics (6.1.36490.0), DisplayLink Core Software (6.1.36484.0) and the driver of USB is Asmedia ASM104x USB 3.0 Host Controller Driver (1.14.4.0) installed on 2012-03-07 Status is Installed.
