Can we ask the person who made this post:

https://forum.libreelec.tv/thread/4235-dvb-issue-since-le-switched-to-kernel-4-9-x/?postID=75965#post75965

to run the test?  The post says that the testing was done on an x86_64 
machine.

Can you try running the same test on an x86_64 system? Alan Stern

It appears that you are using a non-standard kernel.  The vanilla 
kernel does not include any "dwc_otg_hcd" driver.
