I have an ML2 that has quit working. I had 2 of these for some time running with an extra USB fan blowing on them in addition to their own fans as an extra measure of cooling. The fan on the unit still works when I swapped it to the other working ML2 and vice versa.

Is there any other testing that can be done to see if this is completely dead or still salvageable?

Not sure if this means anything but when I plug it into my USB power monitor the screen blinks rapidly.

you should be able to see it as a COM device under device manager, if it does not show up there then either windows blocked the silicon labs driver and/or you need to reinstall it. If it still does not show then yea it could be dead. No reason something is wrong with it if you haven't overclocked it like crazy or overheated...they should last a pretty long time.

You can also try a different system in case its system related.

Not showing up under com devices, no lights come on when I first plug it into either my Linux or windows machines

Been running them at clock speed 756 and getting 4.4mhs average. never had an issue until last night when I noticed my hash rate was about half and saw that one unit was not blinking.
