Problem in drone
Hi, I’m having an issue with my SpeedyBee F405 V4. It doesn’t connect to Betaflight or the SpeedyBee app on PC, laptop, Android, or iPhone. USB-C connection shows “Unknown USB Device (Device Descriptor Request Failed)”, and even BOOT/DFU mode isn’t detected. I’ve also tried ImpulseRC Driver Fixer and multiple cables/devices. Any idea what could be causing this?... Earlier I had enabled Bluetooth also but now its showing that urat 4 isnt enabled, but i did it.
