Hi,

I’m having the same problem (on my Android tablet since today).

Android App Version on tablet ist 2.1.35., USB settings are ok (I was using it for months with no problem)

Windows Driver Version is latest capable today (2.2.24)

The tablet opens the viewer app and seems to connect but after some seconds it closes the viewer app and shows the error message “USB session connection lost”

Thanks for any help.

Cesar

Buenos dias, muchas gracias por el trabajo, sin embargo lo acabo de probar y sigue sin funcionar.

No funciona, sigue saliendo exactamente el mismo mensaje, “Se perdio la conexion USB”.

Ayuda por favor.

Hi @isai, @gerhardkiessling,

If you have “Samsung Android USB Driver” installed in your PC, please uninstall it, then reinstall the latest spacedesk Driver Package, and restart your PC they try connecting again via USB.
Also, please open command prompt and run “pnputil -e” then copy the output to Notepad and save as text then attach to your next reply.

Another suggestion you may try is to change the USB slot you’re using, or use older USB 2.0 cables to connect. If you can, please try to use USB 2.0 cables to check if they work on your end.

Thank you.

It’s even worse than before. At least before I could connect to Wi-Fi; now, as soon as I open the Android app, it immediately tries to connect to the USB session, regardless of whether I’m actually connected via USB or whether I disconnect the USB cable from the Android device on the controller console. So, even though the Android app shows the option to connect to Wi-Fi when I try to restart the app, the console screen goes black instantly, displays the message “USB session connection lost,” and exits the app.

In other words: before, the “USB session connection lost” message only appeared just if I had “Usb Cable Android” option activated in the driver console, so I could chose Wifi. Now as soon as I open the app it  tries to connect to USB option.

Actually I dont understand how to follow the new steps you suggested above about pnputil-e so I couldn’t help you this time. I tried with reinstalling spacedesk Drive Package and new app version and it gets worse.
