Just updated to rc10 today. Programs written outside the client application still work fine, however ALL web control and test programs used within the client no longer work on channels G and B. This includes the ‘ALL OFF’ button, which worked in rc09. All tests to channel R work flawlessly.
The only difference between the channels is that the addressable LEDs on channels G and B are running off external power, and only connect to the Blinkstick via the Data line, whereas the addressable leds on channel R are running on USB power through the Blinkstick.
Edit 1: Rewired Blinkstick and all LEDs so that the blinkstick had no power passed through it to any LEDs. Added a master ground connected to all devices. This made no difference.
