Keyboard power issue #14

Closed zeke7237 closed 7 months ago

zeke7237 commented 7 months ago

I have an Agon2light, and recently received my Cerebrus 2100. I fought with keyboard issues for a few weeks, none of the keyboards that worked with Agon would work with Cerebrus. No powerup sequence on the keyboard lights. I ordered another keyboard (from Agon Australia) just to be sure, and it didn't work either! I was looking around at it again this morning, and discovered that if I plugged in the keyboard AFTER powering up the Cerebrus the blinkenlights appeared and the keyboard works! I'm going to attempt to look at the firmware..

This is not normal. CERBERUS 2100 should have the keyboard connected before power up. All keyboards that work with Agon should work with CERBERUS.

Please let me know if you found out what the problem was.

Unfortunately I'm in the middle of moving, so I won't have my tools and test equipment available for a while. I'll report back when I can.
