First of all, you don't need or want R14; the ESP32S3 already has that resistor built in. Secondly, did you reset the chip with GPIO0 low? If so, the USB peripheral can't get you out of that state; you'll need to reset the chip with GPIO0 high. I should have labeled R14 as "NOT POPULATED". That was...

Hello. I have been using the ESP32-S3-DEVKITC fora bit now and it works great on either USB port (serial or native). I went ahead and decided to move to a custom PCB proto. Though the flash monitor process does not appear to be the same. Usually I am able to see the log messages right away after fla...

I really don't mind. I have sent things to China before and it got there okay unless the logistics issues are more involved than using DHL. But if it is not possible, I am not sure how else to troubleshoot the getting it to recognize it as a DFU device. The issues are on this side; a fair bit of Sh...

[ What is an address that I may send it too? Would you rather have one that is untouched or with the efuse already blown? Or both? That's kind of you, but there's all sorts of logistics issues here that probably makes it faster for me to wait until I can get some from the office somehow. I really d...

Using zadig is very easy, just follow this (or similar) vid https://www.youtube.com/watch?v=WzTq5ZWdhRM

From dropdown list select esp32 S3, and if you are not sure which device is it, then check USB ID to match VID:0x303A and PID is 0x0001 or 0x0002, dont remember.

Thank you for this!

Note that Zadig won't help you when the USB device is not detected successfully. I'd love to double-check the DFU functionality here, but due to Covid troubles here in Shanghai I don't have access to an ESP32S3 in the short term, sorry. That is what I was thinking as well, it should be detected aut...

On windows you have to use "zadig" to install espressif VID/PID as WinUSB, before it can be recognized. Also this website will not work to DFU esp32 Sx, because it can detect only preconfigured VID/PID, but there is few other websites that would work: https://devanlai.github.io/webdfu/dfu-util/ Ok ...

Yes when I press the boot pin on the devkit board, IO0 does indeed go low. Same with reset. I hold down boot, then press reset, let go of reset, and let go of boot. The PC does not react at all. I feel like there is a step missing somewhere in the instructions we are overlooking. Do you have a brand...

An external pullup is not needed and adding one does not lead to progress here, as simply putting the resistor on the D+ without the ESP32S3 connected would lead to the same result. What fuses did you try to burn exactly? Can you give an output of espefuse.py? I burned the USB_PHY_SEL fuse per the ...
