Public bug reported: I have recently acquired a acquired a desktop running ubuntu 20.04. I have several computers and switch between them using this KVM https://www.amazon.co.uk/gp/product/B077SV9MMQ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 The other machines are either running windows or ubuntu 18.04 or earlier. They are all fine, but the with 20.04 machine neither the keyboard nor the mouse works. On the 18.04 machine I can see

On the 20.04 machine only this appears lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 0b05:19af ASUSTek Computer, Inc.

The failure first appears in 19.10 and is still present in 21.04 I can observe a similar problem with a dual boot laptop running windows 10 and 20.04. With windows 10 I can use it with the KVM for screen and keyboard/mouse, but with ubuntu 20.04 the keyboard and mouse do not work. This issue has also been observed here https://unix.stackexchange.com/questions/646515/using-logitech-mouse- keyboard-on-tesmart-kvm-switch-with-ubuntu-20-04 and I have observed it using a Lindy 2 port HDMI/USB KVM (but I'm unsure of the model). I had to report this originally against xorg as this bug reporting system seems not to allow reporting of bugs against unknown packages. I also had to report it through the ubuntu-bug executable as I've been unable to find a way in launchpad of reporting a bug (as opposed to getting a guided tour about reporting bugs). I am happy to supply more info and test fixes if I am asked but as with this type of bug where something fails to happen rather than something wrong happens I don't know what to look at.
