I just notice that USB power sensor U2000 series require almost 5 minutes to load the driver for each new power sensor. The strange thing is that all them are the same model just different serial number. Why windows 7 needs to reload the driver for each new serial number?
It feels like I will retire (that happen in 20 years) before this thinks connect to PC.
The PC is windows7 I3 core with connection expert version 17.1.20011.4 (if that matter)
I notice that because I run firmware upgrade for all our U2000s power sensors and I waiting time for waiting for the connection.
