No LED activity on STD Color /w latest FW #130

I upgraded one of my spare STD Color OKs to latest firmware (OnlyKey v2.1.1-prodc). This was via the Teensy method first to get to OnlyKey_Beta7_STD_Color.cpp.hex then inapp to get to latest.

However it seems there is no LED activity at all. Not when I plug in type or anything. I changed brightness in the settings from default to 10, but that didn't help. TBH not sure what the LED status was before the upgrade, but wondered if I did anything wrong? Maybe its a HW fault?

Can you try plugging into a USB hub? Early hardware models ~2017 had an LED that had issues on some systems where the USB voltage is higher than spec.

Since you are using the legacy firmware upgrade you must have one of these legacy devices.
