@stormi Thanks. I'll cross my fingers for a fix, at some time.
I also updated yesterday, on my ODROID H3+. Everything worked as expected.
I noticed that /etc/xensource/usb-policy.conf was send back to stock configuration, so I readded my modification to it. I'm not sure, if that's the expected behavior, after the host update + restart.
Thank you for the latest update

@stormi Fair. Are there any public issue to follow? Maybe I didn't do my search that well? Thank you for the answer.
@stormi Thank you!
Are there any planned work related to hot backups of VM's, where a USB device are attached? It's currently not possible.
In the weekend I ended up moving a single container to a alpine image, so I could continue backing up my primary docker VM. But I was hoping to have rolling backup of the alpine VM, too
@mdavico Saly, I also get a VM_HAS_VUSBS(OpaqueRef:***/removed/**) error message in 8.3, if I have a ongoing passthrough.
I'm not sure if it's the same thing with backups. If it is, that's problematic. One of my instances needs the USB Passthrough, but I need the rolling backup.
I'm jumped on XCP-ng 8.3 on my bleeding edge ODROID H3+. Are there any plan to support the build in sensors in the host system at some point, so it's possible to get CPU package temperature readouts? Right now, I've not been able to make any readouts from the host-machine, where I've tried a few sensor terminal tools 
.
@mdavico Are you asking if it's possible to get one processed, even though a USB passthrough are currently enabled/active on the KVM, or? 
I think you need to be a bit more precise.
