Question in regards to WINUSB failed to initialize.



I just posted a potential solve for stutter, audio crackeling and shimmering that seem to plauge pcvr. The reason i'm mentioning it is because of that tedious adventure i've found that some things fail to initialize when starting the oculus services and i have questions. I'm refering WINUSB in perticular, but there are more things that seem to fail if you want to look into it. (debug tool > services > make console visible)

So, my thought process at the time was that winusb might be the reason for why the usb 3.1 gen 2 port only show up as 3.0 and only deliver 1.5 Gbit/s. This is obviously not the case for me as there seem to be some sort of bios problem and i don't think others achive higher speeds than around 2.2 gbit/s to the quest. 

Anyway, WINUSB failed to initialize because of lack of memory. I have plenty of RAM so it probably has to do with the memory windows allocates to the process. So i doubled the maximum allowed heap allocation in regedit, as you do, to no effect.

So my questions are: What is WINUSB respossible for? And is there a benifit to getting it working? also, is there a way to globaly change OpenXR settings or can i only do it on an app per app basis?

Hi! Thank you for the advice!

I haven't had the time to try it out yet, I'll get right on it tomorrow afternoon. In the meantime; Would it be possible to know what WINUSB is responsible for? And as i've noticed that framethrottle introduces stuttering i was hoping there was a way to change the OpenXR setting globaly rather than on an app by app basis.

Thank you in advance. Will report back tomorrow.

Hey again! Not to worry; take your time, and we'll be here ready to move forward. As for your questions about WINUSB and the framethrottle introducing stuttering, we think those would be better suited for our developer forums, which can be found here. We do hope to hear from you soon regarding those steps previously shared! Until then, have a great day!

Hi! I tried all the steps you suggested and things still seem to fail to initialize. Here are the screenshots from the console if they help ^^.

Well, i installed other drivers to a usb hub that doesn't use winusb. When winusb isn't used by the server i can get most of the stutter in games to go away.



So, winusb can only interface with one interface at a time which introduces stutter. 

Please enumerate the appropriate driver to \\?\usb#vid_1004&pid_62c6#vs12345678#{a5dcbf10-6530-11d2-901f-00c04fb951ed. I think it's the XRSP that deals with the streaming. Even composite drivers are to much for winusb to initialize.
