host send USB set address packet one time, device handle twice

[DatanIMU]

Operating System

Windows 10

Board

CH32F103C8T6

Firmware

webusb-serial

What happened ?

CH32F103C8T6 is very similar to STM32F103C8T6. I use "make BOARD=stm32f103_bluepill all" to compile and flash image.

after power on, windows host send 80 06 00 01 00 00 40 00, while device send 18 bytes.

it seems STM32F103 have the same precesure, and win10 usb works well.

issue seems to be Set Address handled twice after power on by device, while host only send one time.

How to reproduce ?

1. CH32F103C8T6 have USB pull up resistant inside. during board_init, enable USB pull up resistant after GIPO init and before USB clock enabel according to CH32F103C8T6 's manual.
2. compile as usual.
3. issus happens every time

it is not the bug of this library, Since stm32f103 work just fine. Each mcu has their own special thing to port so that I could work with the stack. Similar mcu within a same vendor's family has their difference as well,

I don't have the mcu, therefore I don't think I could help. It just an porting question for a new MCU. Convert to discussion for other with the same MCU could join to help.
