Problem with USB keyboard input to Sipeed LicheePi 4A board
- At present, we have not encountered any customer feedback on this problem.
- Please check the USB keyboard itself, replace it with another keyboard, and whether the receiver of the keyboard has poor contact or is damaged?
- Check whether the power supply of the motherboard is sufficient ?
I have 3 spare keyboards; each is a different Logitech model.
Two of the three, when plugged into a USB port, produce the symptoms
described in my original issue (email). The third, and oldest, keyboard
works ok! So I have circumvented the problem, which I am guessing is
related to the electrical level presented by the keyboard, to the USB port.
