Detailed Description

USB descriptors of the ACwing FC (CDC virtual COM port).

VID/PID: 0x0483/0x5740, ST's "Virtual COM Port" pair used by the STM32Cube CDC examples, so the standard CDC-ACM drivers bind on every OS. It is fine for development; a product needs its own VID/PID. Written after the ST template usbd_desc_template.c.
