Betaflight needs two different drivers on Windows 11, because a flight controller shows up as two different USB devices. In flight mode it is…
“USB JTAG/serial debug unit” is not an adapter you bought. It is the USB port built into the ESP32-S3, ESP32-C3, C6, H2, C5, C61…
There is no such thing as an “RS485 driver”. Every USB to RS485 adapter is a USB-to-serial chip (CH340, CH343, FT232R, CP2102 or PL2303)…
When an Arduino UNO R3 or Mega 2560 R3 shows up as “ATmega16u2 DFU” or “Arduino Uno DFU” with a yellow triangle, its USB…
UNO R4 Minima vs UNO R4 WiFi on Windows 11: the Minima's DFU-RT interface needs Arduino's WinUSB INF (mirrored here with SHA-256), the WiFi's ESP32-S3 bridge needs nothing. Every USB ID (2341:0069, 0369, 1002, 006D, 303A:1001), the driver package version by version, and the fix behind each forum error.
CH552, CH549, CH32V203/V307, CH582 and the other WCH chips with a factory USB bootloader all enumerate as 4348:55E0. WCH's WHQL CH375 driver vs WinUSB: what Device Manager shows, which driver WCHISPStudio, wchisp (release vs nightly), ch55xduino and chprog can open, and how to enter the bootloader family by family.

An Arduino Leonardo, Arduino Micro or SparkFun Pro Micro has no USB-to-serial chip: the ATmega32U4 is the USB device, and it presents two different…
