usbhid/hid-core.c already sets HID_QUIRK_NOGET for regular mice/keyboards [1].
Maybe adding ALLWAYS_POLL to those would make sense and solve your problem?

BTW I am against having this quirk as the general default because we
rely on the usb autosuspend to shut off the touchscreens when no one
listen to them, and the touchscreens are draining a lot of power.
