I have a problem with Diolan DLN-2 modules.
When running XP, when booting up computer from shut down state, the DLN-2 shows d1 and d2 LEDs on dimly. But not flashing like normal heartbeat. The USB device is not recognised by the operating system. Re-plugging in the DLN-2 to the USB once the computer is already on fixes, heartbeat LED resumes, and system recognizes.
In windows 7 same issue happens but LEDS appear normal on boot. DLN-2 is still not recognised until re-plug.
We use these in a production environment, and it is a hassle to have the line workers re-plugging parts of the test setups to get them to work.
Is there any firmware upgrades or assistance you can offer to fix this problem??
