Last week I tried unsuccessfully to move a USB port from a MIDI device. Currently, the micro USB port is located on the right side of this Novation Launchpad Mini, which isn’t compatible with the stand it’s going in.
“Easy”, past Jagmills thought to himself, I can just add a cable soldered to the USB socket’s pins and route it out the back, giving me what I need.
Sadly, I’ve failed miserably in this effort - my PC would not “recognise device” when connected to the soldered cable, and so began a fervent and fruitless attempt at getting it to work, which resulted in much Leoing of the original PCB.
Here’s a picture scraped from the internet of the PCB in question:
The USB port on the left has 6 pins - shield (grounded), ground (grounded), v+ which goes into the large rectifier thing below it, ID (which was unconnected) D+ and D- which go under the crystal, to a small choke, through two 4k7 resistors and into the STM32.
