I was experimenting with MAIPLE mini.
I wrote to the DEVICE Maipleminibootloader of STM32F103CB,
That is USB DEVICE
DVICE is recognized as unknown as "6 & 176E48BB & 0 & 1 USB \ VID_0000 &
I use the DEVICE of STM32F103C8
Be properly recognized "USB \ VID_1EAF & PID_0003 \ LLM_003".
Omit the cutoff 3.3vpullup to deal with USB-HISPEED, I have to remain connected.
Although the same to another substrate using a STM32F103C8,
I recognize correctly.
I will be recognized if you care what the point?
