How can I set up a "USB proxy" for /dev/ttyUSB0 over the network?

I have a device under test (DUT) and I measure its power usage the using a Power Analyzer Datalogger using the data from /dev/ttyUSB0. The problem is that the DUT is now remotely from the workstation I used to gather data with, but in the same network, I need to use a 2nd PC which is directly connected via USB to the Power Analyzer as a sort of USB proxy and ssh to create a kind of symbolic link on the measuring machine of the USB of the "proxy" machine. Given the above diagram how can the 1st PC access /dev/ttyUSB0 of the 2nd PC which is directly connected, in a way that a program reading the stream from the 1st PC will not notice the difference?
