Hi, i tried with the ESP32-S3-DevKitC-1-N8R2 board. My usbip client shows the right ip and i can connect. But if i want to attach the usbip to my server it shows the following message: usbip: info: no exportable devices found on 192.168.178.***

is there a special device class to test with? maybe an usb stick or something else?

thank you!

Im not sure you know the purpose of USB/IP. You have to connect any USB device to pins 19/20 (D+/D-) on esp32S3 and the GND and +5V to power that device. Not all device are working thou, even if usbip can detect and list, or even to mount on PC. There is problem with pendrive, at least on my linux, because the driver on PC is trying to SetAddress, which is not implemented. You can test with any USB to UART, esp32 devkit or other devices.

ok. i will try.

on my devkit the usb pins (D+ and D-) are on Pin 20 and 21. Do i have to change these pins in one of the header files ? At the moment i try with an OTG adapter on the onboard USB port. I thought the USB port is already connected to the right pins.

This OTG port should works. Your D+/D- are the same as for all S3 devkits, 19 and 20, you just misread it.

ok. I will try another OTG adapter next. I connected an usb-serial adapter to the USB Port of my S3 and again usbip: info: no exportable devices found on 192.168.178.xxx

it seems that there is no power delivered through the usb (OTG) port.

After adding external 5V (VBUS) to my device it is working.
