Displaylink 7.6/Duplex Speed

[Wragg1]

Hi;

This is for a corporate environment - I’m hoping to get an .msi installer for 7.6 with the Duplex speed set to 100Full. I've already emailed the corporate installer address but thought I'd follow it up on here.


We are installing Toshiba Displaylink v7.6.56443.0 but we’re unable to set the Speed & Duplex value to 100Full automatically. The default is set to Auto Negotiation.

I think the easiest option to resolve the issue would be to modify the .inf file referenced in the installation.
In the DisplayLinkCore.msi, there is disk1.cab. Within this cab is dlcdcncm.inf – and this section in particular within there is what I need changing:

HKR, Ndi\params\*SpeedDuplex, ParamDesc, 0, "Speed & Duplex"
HKR, Ndi\params\*SpeedDuplex, default, 0, "0"
HKR, Ndi\params\*SpeedDuplex, type, 0, "enum"
HKR, Ndi\params\*SpeedDuplex\enum, "0", 0, "Auto Negotiation"
HKR, Ndi\params\*SpeedDuplex\enum, "6", 0, "1.0 Gbps Full Duplex"
HKR, Ndi\params\*SpeedDuplex\enum, "4", 0, "100 Mbps Full Duplex"
HKR, Ndi\params\*SpeedDuplex\enum, "2", 0, "10 Mbps Full Duplex"


Currently, the default value is set to “0” = Auto Negotiation. I’d like this to be set to “4” = 100 Mbps Full Duplex.

Is this something that can be modified within the .msi? If not, are there any other suggestions as to how I could automate this change to the Duplex speeds?

I am aware that this can be modified within the registry under the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}

but this can only be done post-dynadock connection and we have multiple laptop models which means the relevant subkey \#### differs between them - so ideally we'd like to avoid that.


Thanks
