Touchback not working with USB-C display (Surface Hub 2S)
Or simply ensure I plug the USB-C cable after a fresh start ?
(I'll check it out tomorrow morning Japan time)
Microsofthi dgr4it,
If I understood it well, plug in the USB-C after the restart but would help if you could try both
Thank you,
Cezar
Thanks for the info cezarcretu
I'm afraid however, tried both ways with both computers (only one cable this time around).
- Plug the USB-C cable after a fresh start (power from shutdown)
- Plug the USB-C while shutdown, then start the Surface Hub 2S
Unfortunately, still the same issue (have mailto:4k@60Hz video and power delivery, but touchback not working despite being recognize as "Guest Touchback Board" in the PC side.
Wonder if there might be a firmware update dealing with these issues, but since I have no admin rights to the Hub it's hard to tell if it's up to date or not.

Hello dgr4it,
Could you try with another USB-C cable or test with another device?
If this returns the same behavior, kindly open a support case to investigate
Thank you,

cezarcretu One last question, on top of my previous question on the particular cable you linked.
I have noticed that the https://docs.microsoft.com/en-us/surface-hub/surface-hub-2s-connect website lists the maximum resolution being mailto:4K@30Hz, whereas all the devices are mentioned were outputing mailto:4k@60Hz through the USB-C connection.
Could it be that touch&pen back don't work when using 60Hz ?
