I don't think so.  ehci is still considered unfinished in 5.3.  The
manpage has the following:

     The driver is not finished and is quite buggy.

     Currently there is no support for hubs that are connected with
     high speed upstream and low or full speed downstream (i.e., for
     transaction translators).

     There is also no support for interrupt or isochronous transfers.

I recently tried to plug ehci into my kernel and all I got for my
trouble was a kernel panic.

Good luck
