[leoli51]

Hi, we created the board definition files for the upcoming Melopero Shake RP2040 development board.

please update the VID/PID to one that you have permission to use

Hi, the allocation PID: 0x1005, VID: 0x2E8A is reserved for us, the reason why the Melopero Shake RP2040 is not yet on the list is because we are waiting for the launch (which is imminent).
We just asked the Raspberry Pi to activate the PID with our product's name on the list.
In the meantime, we may provide you with an official PID assignment document if needed.
Thank you.
