Hi Dann,
Thanks for looking into it. I am trying pi 3b emulation at the moment,
as I want to try things out with VMs instead of the real SBC. My target
is to try things out before deploying to the real SBC, hence why I want
to use emulation of specific machine type. I see that most tutorial

Thanks for looking into it.
1. raspi3b or similar ARM machines do not support ACPI, so the
snippet should not exist in libvirt VM's domain XML, or it will complain
this or that, refusing to start just as you'd tried. That's also why my
example machine XML does not have it.
2. without the snipp

Confirmed to work now after upgrading to linux-image-5.4.0-1012-raspi,
which also fixed the warm boot issue I'd reported in 1871977.

I just updated kernel to have OTG working again as per #1861070, and can
tell that EEM support is still missing.
/sys/module/g_ether/parameters has no entry of use_eem has per "modinfo
g_ether" mentioned.
Sorry OTG is not working on my Pi4 after upgrade to Focal, so I cannot
tell. Again, pls. refer to bug #1861070

Hi Hui, just in case I tried again, but no it won't work if I put
"dtoverlay=dwc2" w/o dr_mode. I remember dwc2 should be new code and
should be used, hence why I use that instead of dwc_otg.
Anyway, if we use "dtoverlay=dwc2" only, I guess the actual "dr_mode"
value may not be init properly in r
Sorry, too haste, seems like it works a bit different than Raspbian.
Using your new kernel with this set in usercfg.txt, OTG mode is working fine.

though with Raspbian, only "dtoverlay=dwc2" is needed, which was what I
was using.
