Hi, Seeing this same thing! And I'm on Ubuntu 20.10, so pretty current :-). vt82c686b-usb-uhci doesn't seem to be accessible any more, but trying qemu-xhci => no joy, still have to reset the VM after each startup, to get the keyboard and mouse working.
Is this expected?

My minimal example to verify this bug is the following: qemu-system-x86_64 -M q35 -m 128 -cdrom mini.iso -usb -usbdevice host:04ca:005a -vnc :1 -display none Using a noname USB Keyboard with ID 04ca:005a and the Ubuntu 16.04 NetBoot mini.iso, I can see the boot screen of the Ubuntu ISO through VNC, but pressing the arrow keys doesn't do anything. By taking out the "-M q35" parameter, QEMU switches to the traditional i440FX system. The passed-through USB Host Keyboard works there, but the old platform is no option for me.
