I'm facing a weird issue on Pi Zero when trying to leverage a USB wifi dongle that I directly soldered to the zero pins, as described here here.
What happens is:
- If I leave the micro-usb port empty, with nothing connected to it, the wifi dongle just won't come online.
- If I connect a simple extension cable to the usb port, the dongle starts working perfectly. This is reversible, ie. as soon as I disconnect the extension cable, the dongle dies and the only way to have it back online is to reconnect the extension cable.
any suggestions?
thanks
