error: No connection could be made because the target machine actively refused it.

Hi,

I/m using a Raspberry Zero with a clean install of Debian Bullseye Lite and a laser engraver connected to its USB port. USBip makes a successful bind on that side.

On windows 11, after installing USBip I try to access it but get the following error:

error: No connection could be made because the target machine actively refused it.

I can successfully ssh to the raspberry, its IP address is correct, I also used Virtualhere and successfully connected to the laser(but communication freezes after initial connection, that's why I'm trying USBip).

Do you have any idea how I can proceed?

Thanks!

Hi, usbip daemon must be running on server side. sudo usbipd -D

You were right, I somehow missed that.

Unfortunately a connection with the laser engraver cannot be established. The device appears in Device Manager but the control software(Lightburn) either hangs or simply waits forever for a connection. The engraver uses an ESP32 so it's USB-> Serial, I don't know if that helps at all(Creality Falcon). I know there are many people online that have successfully connected their lasers but I believe I've done everything right. I connected a thumb drive and have no issues there, I can freely browse and play videos from it. I tried both UDE and WDM drivers.

You could gather driver log, sometimes it is possible to fix issues without having a device.

usbip-flt.txt usbip-ude.txt CMD Log.txt

After I started logging, I attached the device, ran Lightburn and issued a couple of commands(Go to Home, Frame, Device settings etc). Lightburn never managed to connect(I get a "Waiting for connection" message). In device manager it shows up successfully under COM/LPT ports tab as USB3, and the esspresif Serial to USB embedded in ESP32 under one of the properties tab.

I've attached the log files, I wouldn't know what to make of them but you might find something in there. Given that a thumb drive connects just fine I think this has to do with how this particular laser engraver communicates which might be different to other engravers that communicate successfully through usbip.

Unfortunately, there is nothing unusual in the log. Transfers are successful, can't find out the cause of the issue.
