I have 2 Solar chargers connected to a battery bank & a multiplus2 48v 5000
BMV 702 & CCGX
VRM shows Data from BOTH Controllers
CCGX shows second controller not Connected under devices
No second Controller is Displayed in CCGX
2nd controller connected via USB adaptor
Picts Attached 
Hoi,
Can you connect the second mppt into the first (working port for mppt 1 ) usb port? Maybe bad usb port / hub
Had the same 3 weeks ago, i had a bad usb hub.

Ok I have both connected according to CCGX control Devices
(no longer not Connected)
Originally had one via USB 1 via VE Direct
Have tried to connect both via VE.Direct to USB interface cables
No Change
Attempted to use a HUB both to hub then hub to CCGX usb Port A or B
NO change
Tried a Powered HUB
Can Monitor Both Units on VRM & Via Victron Connect App
Should i see 2 PV chargers
on the CCGX GUI Display
or a combined display of 2 calculated total of 2 inputs on 1 PV unit
Also Both connected at same Point to Batts yet 2 different batt bank Voltage Readings on Victron Connect & in VRM Dashboard
