If you have the right udev rule around that echoes 1 to the bConfigurationValue of the usb device in sysfs, then after replugging the device udl should see your device and you should see evidence of it in your dmesg log.

So I am trying to setup a situation where I have multiple devices. The smaller touchscreens are using DL-165. I am thinking about the "brain" - main touch screen being an AOC with your new chips. Based on what you are saying, it will not be possible to get the legacy chipset and the new chipset to run on the same machine?

No, they should be fine together. The rule for setting the bConfigurationValue should only fire for devices which have configuration 2 by default, and it'd switch them to 1, allowing udl to see it - this would apply for DL-1x5.

The udev rule that we install for evdi (that starts DLM) is specific enough that it should not match old devices.
