Since Update to 1.7 all USB devices are pretty unrelibale

[snailcatcher]

Hi there,

I updated my Neptune 4 Pro to OpenNeptune 1.7 (I flashed the eMMC again and did basically a fresh install).
Since then it seems like I have Issues with all USB devices.
I have a simple old usb 3 hub connected to my USB port. On this hub is a WebCam and a Wifi dongle. All of them has worked flawlessly on 1.5 before for almost 2 years.

But something changed, because since the update the following is happening regularly:

• the printer takes at least twice as long to boot
• the performance of my WebCam is way worse (almost half and even with low resolutions and low fps (I tried several of them).
• my wifi connection sometimes break and will not come back unless the printer is restarted (USB unplug and plug in again will not help)
• If I use the openneptune commands via ssh it seems that all of them have become slower.

So all in all it feels like all of the stuff is running on a single CPU now instead of a 4-Core. Or something needs way more resources than before.
Maybe this is an Armbian issue, because it seems that the whole system is affected?

I have everything up to date with the latest main branch at the moment. (But I will try to use the dev from now on, because I saw all the affinity changes)

If I can help somehow or provide some more information let me know.
This firmware was awesome for the last 2 years and I want this experience back :)

I have found a way to reproduce the Wifi issue:
If I start a Print and press the emergency stop button in fluid and then restart both klipper and the firmware the connection gets lost.
Neither fluidd nor sending prints from the slicer will work until I power off the printer completely (If you are too fast the issue persist even a power off).
