Black Screen when using USB connection
Hi there, i have a Lenovo tablet (and a Motorola Phone). Both have the same problem, only works with wireless connection. I don`t know how to make it work (tried changing the codecs, using diferents ports and cables, switching between modes in usb conecction). I attach here the link to the debug results:
EDIT: Removed Google Drive link
Hi @federico-2,
the Google Drive link access is private and we could not access it.
Please attach the diagnostics folder (.zip) in your next post.

Hi @federico-2,
were you trying to connect by USB cable?

Yep, I tried the 3 methods in the manual, but same resul. Black Screen and no detection of screen in the pc.
Hi @federico-2,
Can you provide the models of the devices you’re using? In your Primary PC, does it have a USB4 port? Is USB Debugging turned on or off in your devices? Also, is there any Lenovo or Motorola specific software installed in your devices? Thank you.
same is happening with me.. i have a lenovo tab as well.. i had samsung usb drivers installed so i uninstalled it and also removed the screenXpert which comes with asus utility for secondary screen
Still it doesnt connect.. as soon as i connect the tab black screen appears in spacedesk.. i change the mode to file transfer yet as soon as i connect the device my tab automatically switches back to no data transfer mode ( all while black screen appear in spacedesk application )
Hi @priyanshu,
Please reboot your machine then use the latest spacedesk Driver Package to either repair or reinstall spacedesk in your Primary PC then try again. If this still doesn’t fix your issue, please send us the logs of your Primary PC by opening the spacedesk Driver console as administrator and clicking on Diagnostics then follow the steps below:
1. Download the DebugView.
2. Check the Diagnostic Collection box.
3. Reproduce the issue e.g. by connecting the spacedesk Viewer app.
4. Uncheck the Diagnostic Collection box.
5. Click “Save All Information” button (this might take a while to finish).
6. Compress/Zip the folder which contains the logs, then attach to your next reply to this post. If the folder exceeds 512kb, you may upload it to Dropbox or Google Drive then include the download link on your next reply.
Thank you.

i tried to replicate it… rebooting and reinstalling the application on both the laptop and lenovo tab wasn’t helpful..
Hi @priyanshu,
From the logs, it seems that you have not rebooted your Primary PC and repaired or reinstalled the latest spacedesk Driver Package after uninstalling the Samsung USB Driver. Also, there are missing files in the logs you sent. Please make sure to run the spacedesk Driver Console as administrator as mentioned in the previous instructions I sent before following the steps. Thank you.
