Greetings

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 &
PID_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?

Best regards

As the STM32F103C8T6 also has 128KB flash rom, the STM32F103C8T6 and STM32F103CBT6 are most probably identical chips. The boot loader will work on both types.
You must have a 1k5 pull up resistor on the USB DP+ line, and 22Ohm in line resistors in the DP+, DP- lines.
