So I've had this Poker II for around 8-9 years and only in the past few weeks have been experiencing an issue where upon initially receiving power (eg: via system boot or by first plugging it into a USB port) it will flash the LED beneath the caps lock about 3-5 times then subsequently won't be responsive to inputs.
If I replug the board into the USB following this however it the LED lights up once (the usual amount) and becomes responsive to inputs.
On a different system OTOH it continues to flash indefinitely after receiving power and re-connecting the board makes no difference.
Any idea what might be causing this/how I could diagnose it?
