I have tried 3 brand new port replicators. The last one was the 4338.
The USB ports on the port replicator will not work. I get "Unknown device" in device manager.
I have run all the bios updates, and system updates, and hardware checks. I even used 2 other peoples lenovo laptops and they get the same problem with all 3 port replicators.
Personally i think Lenovo is putting out garbage that doesn't work.
is anyone else having problems with the USB ports on the port replicators?
