Hi,
Recently Synaptics collaborated with Dell on a plugin [1] for fwupd that allows
flashing Synaptics MST hubs using the DP aux interface to manipulate the DPCD
[2].
Currently the plugin hardcodes the max number of DP aux devices to look for to
3 (as that's what we've seen so far on HW), but we were wondering:
1) If there is a way to query the number of devices that the kernel is
going to be creating?
2) Are there any instances of more than 3 devices in the wild today
that anyone is aware of?
