Do you have the external hub plugged into its own power? Or is it just drawing power from usb? You might try booting into the previous kernel and doing a quick test, if it works there, then it is may be a new feature enforcing something that might have happened or work, or it may simply be a a kernel bug. The standards on usb say how things are supposed to work, but often until ignoring the standards translates to a bug, no one enforces it in software. It could be doing a power calculation and determined there is not enough power based on what the devices say they need and how they are wired, and disabling anything over the power limit. Likely whatever gets seen first gets the power(or other resource) and anyone later won't get turned on. I know that the usb bus does this on the bandwidth a device claims to need, because of that you cannot run 2 webcams on the same usb bus that each want 80% of the bandwidth to run. The 2nd one will not be allowed to work. And most motherboards only really have 2-3 real usb ports with all of the ports really coming from internal hubs.

So if it is a hardware failure, it has worked perfectly since I got the board a year ago and failed after I updated and rebooted this afternoon. Can't say that didn't happen, but it seems really co-incidental. > >> I'm assuming the southbridge chip (or whatever it is called) >> is dead or at least half dead. > > > X570 is an AMD AM4 motherboard.
