Joystick was working fine, downloaded a revised program from easyC and joystick went to four solid red lights.
Downloaded firmware, re-synced and still red.
Recharging batteries now but do not believe that’s the problem.
DaveP,
This usually means really low AAA batteries.
Which LEDs were you getting if connected to the PC using the USB A-to-A cable?
A LED chart can be found in page 8 of the following document: http://content.vexrobotics.com/docs/VEXnet_Cortex_UserGuide_081811.pdf
