windows kernel and USB question

[diep]

Hello!

Thought maybe someone here might know it. As in linux kernel i pretty much understand how locking works there (not very great in linux) but windows is a mystery here to me.

It's about my 44 core box and. Which i built for just over 1000 euro. A 2 socket Xeon e5-2699v4 ES box (note under full load this ES version which on paper is 2.1Ghz clocks itself in reality back to 2.0Ghz - i do watercool it very wel). I run windows2019pro edition on it. On my facebook photos visible of it publicly.

If i have a device in this case an external USB music DAC (for high quality sound) connected to the windows box and if i run a music MP4 on the machine. Does it still have the same problem then like 10-15 years ago when i toyed with EGTBs and copied files to USB disks - in that windows is centrally locking something - and question is - what exactly is windows locking and what functionality is not possible centrally on the machine if a packet gets sent to USB?

So the symptom i hadback then with EGTbs is that all i/o seemed to get locked on the windows box (that was vista pro at 2 socket machine).

In case of a hardware device like an external USB music DAC - does any of the CPU's that run here 24/24 at 44 cores get interrupted somehow and if they want to store at that moment something to the RAID partitions which are SATA partitions - so not USB disks - does that get blocked by the USB busy streaming audio to the DAC?

Whereas i do not run Diep that much anymore - the cpu's are nonstop under full load (trying to find a prime number).

p.s. Tried install latest intel c++ compiler on the machine to see how well intel c++ is for this box for Diep - but as it seems i need a license from visual studio first to install it. Big bummer.
