5.10 is _VERY_ old and obsolete and way behind in new hardware support,
especially for the dwc3 driver.  Have you tried the latest kernel
release with is many years newer?  How about 6.17?

If you are stuck with an old release for some reason, please work with
the company that gave it to you as you are paying for support from them
for it, it is their responsibility, not the community's responsibility
to manage that release.

And pleaase, do not release new devices on this old kernel version, you
are about to loose security updates in a year for it, which is not good
for the lifetime of your device.

thanks,

greg k-h
