USB device not regonised, no PORT available, link to patch is broken about stm32_hid_bootloader HOT 5 OPEN

Try setting USB support to CDC (generic serial supersede USART) before uploading first sketch after fresh flashing.

it also happens to me, after first upload, my computer can't recognise the HID device until I flash again the bootloader and so on, I'm using maple mini

Same issue here, requires reflash of bootloader after every use

from stm32_hid_bootloader.

It happened to me when I was using MPU 9250 DMP library that crashed STM32F1 because code started to execute too fast. My fix was to add delay(5000) before calling init() function of my library. The cause was probably that external sensor (MPU 9250) was not ready quick enough and this hanged STM32F1.

Now I use HID bootloader 2.2 (and delay) and it works fine for most of the time (I still have to unplug and plug stm32f1 some times, but I do not have to reflash it) . I have USB support set to CDC.

Hi,
Just a quick note, to ensure Serial is well initialized before use them add:
while(!Serial);
after Serial.begin();.
