The unknown device, ACPI\VEN_HPQ&DEV_6001, is HP Wireless Button Driver
I'm having a bit of trouble correlating your machine to the softpaq list.
It shouldn't hurt to try this driver:
This should get rid of the unknown device in Dev mgr, but will not solve the optical drive issue
MS is doing a splendid job with hardware, but doesn't get everything. Two 'devices' (accelerator sensor and another one - can't recall, too lazy to look it up) are not updated through WU. I disabled both of them in Win7, Win8, Win8.1 anyway so I'm not concerned about the Win10 status in Dev mgr.
As long as you know what Dev mgr is telling you, you can decide to 'solve' the issue by installing the driver from the Mfr site - usually. Win10 isn't usually though - so some drivers might not work with it ... yet.
re: the Optical drive issue. I've read some information that points to the chipset drivers, I need to look a bit more.
What does Dev mgr tell you about the following:
IDE ATA/ATAPI controllers
System devices -> SM bus Controller
Universal Serial Bus controllers
What I'm looking for is AMD (the USB 3.0 extensible host is supplied by MS and works well) but the others might clue me in on whether the other AMD chipset drivers are running things or MS drivers are running things.
You don't need to post screenshots for all of that, just take a look and see if they are labeled AMD or not. Let members know if any are not AMD.
If you're up to the challenge (again, I'm not sure if this will fix the optical drive or not),
you might try installing the AMD 14-12 chipset drivers
AMD Chipset Drivers
press the Optional downloads tab on the page to get to the chipset drivers.
Sometimes AMD drivers are a bit wonky to install.

if you find that the install isn't 'sticking'
