ESP32 Forum

Hi,
I attached a USB drive to USB port of ESP32-S3-DevKitC-1 board, and the board can't detect the USB drive. I checked schematic, there is no power 5V (from UART USB) for this USB port, is it a hardware design issue? please search "VBUSB" in schematic, how do you workaround this issue?

thanks,

VBUSB goes to the 5V line via D7. If you're not seeing 5V, perhaps you blew up that diode somehow?

ESP_Sprite, he is saying if you plug in a USB device into the kit, J4 does not supply power to that port.
If he's going to plug in a device into J4 he could jumper across D7.

Ah, 'username' is correct, sorry, I misread.

Hi, just let you know this is a design issue, your competitor uses SR-0805 part instead of Diode D7 to solve this problem. For me, I have no more issues, please close this ticket!

thanks,
Yuping Zhang
