This is the most weird incident i ever experienced concerning with OS/HW !
After my Macbook comes back from the sleep mode, the USB keyboard stopped reacting, seems the USB port even stopped providing 5V electricity.
What i did:
1- Plugged the keyboard to another USB port, it works!! So no problem with the keyboard
2- Plugged other USB devices to the problematic USB port, it works!! So no problem with the USB port
I also reset PRAM and SMC, but still this did not bring any difference.
After, i found out the following thead under Apple discussions:
Seems i am not the one who is having that experience, that's good at least!:)
The solution is:
– Connect any USB extension cable between the keyboard and the USB port, and it works:
This is the most weird situation EVER!!
The question is: How long will i need to keep on using the USB extension, forever?
