CyberPower CP850PFCLCD
I got this UPS for my computer. I want to use it as a starting point to build my another DIY battery backup for my NAS. My NAS supports many UPS, it can shutdown cleanly when the battery gets too low. In order to enable this kind of feature in my own DIY implementation, I need to learn about the protocol used in a supported UPS.

Initialization
Once the enumeration completes, the following Control Transfers occur:

Sample Communication
Once every second, two different reports are sent repeatedly:

The burst of control endpoint transactions here are probably just the Windows driver freaking out. A proper request handler should be able to handle these easily.
Warning: USB errors are expected in power outage events, which means possible occurrence of re-enumeration. It could've been what triggered the control requests seen here.
