Arduino for STM32

You could eventually try to re-solder the USB pins, it may help.

To use the second I2C port you can use following lines as shown in https://github.com/rogerclarkmelbourne/Arduino_STM32/blob/098a98c30e01eeb3f1cf9e9589a74a9263251e7c/STM32F1/libraries/Wire/examples/i2c_scanner_wire/i2c_scanner_wire.ino#L29-L31 (remove comment from the beginning of the lines). For SP...

Please insert to line 124 of

C:\Users\Umer\AppData\Local\Arduino15\packages\stm32duino\hardware\STM32F1\2021.3.18\libraries\Wire/utility/WireBase.h

the following line: and try again.

As I said, always leave the jumpers on default positions "0" (GND) . It is known that USB3 ports do have problems with the board, so better use USB2 only. Flash this BIN file with STLink, or better with STM32CubeProgrammer. If you use/install the latest, it will also install the serial dri...

You don't need to change BOOT0, leave the jumper all the time on 0, and flash the bootloader again.
Which PID is shown on the working laptop?
The 0003 is the PID for the DFU mode, and 0004 for CDC serial.

Which core? Which OS?

Here, in general, only Arduino IDE is supported, as the forum title indicates.
For other IDEs you are on your own. Eventually you may find some answers in the IDE section of the forum.

Which OS?
You need to install STM32CubeProgrammer.

There is a section dedicated for STM8: viewforum.php?f=75
With F401 you can do same (and more) as you want with F103.

According to this link you do it in CubeMX: https://controllerstech.com/stm32-usb-host-hid/

I would use a F4x1 pill and some apps already available on the net, like this:
