I fired up Wireshark’s USB capture. After the standard control transfers, the device sent a vendor‑specific request: 0x5a (bRequest = 90 decimal). The data payload? A 32‑byte blob starting with 0x1e3d198a – its own VID/PID reversed. So when you see vid = 1e3d pid

The drone didn’t crash. It was deactivated – by a device that looked like a $2 cable. Linux A 32‑byte blob starting with 0x1e3d198a – its
