I have the same question as this one about Rock 2F, with additional caveat that it doesn’t have a power button. Is there any way to wake it from suspend?
you can try to wake it by usb key board.

Waking by keyboard does not work. The only way to wake it that I found, if it ever goes to sleep, is to do a hard reset.
Bumping this. Please test waking from keyboard
Sorry, I just asked, USB wakeup is not supported at the moment.
So how to wake this board?
Bump, still this is an issue
Bump.
If there’s no way to wake this board, please just write it, now we just don’t know. Sleep support must then be disabled in the kernel (if that’s how you do this).
Here are the results of the USB suspend and wakeup test I performed on the ROCK 2F using the R3 image:

From the current results, the ROCK 2F does support USB suspend and wakeup. You can try testing it using the R3 image.

Additional note: the USB suspend and wakeup test mentioned above was performed using a keyboard device.
Thank you, must be a problem with my image then
