Description
I tested USB tablet with OHCI controller in Qemu, but it did not work as expected.
The host controller and root hub appear in the device tree, but no USB device (and the tablet input does not work, I get PS/2 mouse instead).
I used command line options -device pci-ohci,id=ohci -device usb-tablet,bus=ohci.0.
I tested with qemu 6.2.0 (huh?) and 9.0.0 with the same results.
Note:
See TracTickets
for help on using tickets.
This prevented me from testing what happens when I restart the system with USB tablet connected to OHCI (i.e. whether quiesce works correctly). When this bug is fixed, this should be tested as well.
