STM32G0B1RCT6 USB_DRD_FS Doubt

Berlin-raj123 · ‎2024-09-26

hi,
Using STM32G0B0CET6
USB_DRD_FS---Host_Only_FS,
USB_HOST---Mass Storage Host Class,
FATFS---USB Disk

USB Interrupt---Enable.

My requirement: i just want to create and write the file to usb_host.c and whenever i pluged the usb, the file automatically copied from microcontroller to pendrive. i did, its working fine but i have a doubt,

Everything seems clear, but why should i configure to Drive_VBUS_FS option.

On my board, I decided to provide 5V to VBUS directly . This makes me wonder if VBUS sensing is possible at all?

And for the Drive_VBUS_FS, I don't want to drive VBUS, but there is no such option available except for keeping the selection at Undefined, which seems to be an invalid state.

we don't have a additional pin of Drive_VBUS_FS, what should i do?

Hi @Berlin-raj123

VBUS sensing are mandatory for self-powered devices only. In your case, you can simply select in the configuration NO_VBUS_DRIVE is needed
