Yet another EFW2 Connection problem
« on: June 30, 2018, 04:28:09 pm »
I've been using an EFW2 for many years now (I'm now on my second one purchased about 2 years ago).  The problem described below happened with both filter wheels, but the problem has been getting progressively worse over the last several months.

What happens is that when I first power on everything Windows 10 does not recognize the filter wheel.  There is an "unknown device" in device manager.  If I unplug the power to the EFW2 and plug it back in then everything works properly. 

This used to happen once every 5-6 times.  Now it happens every time.  I'm using the latest driver package (Native and ASCOM).

Any ideas?
