[Qemu-devel] [Bug 1096714] [NEW] qemu 1.3.0: usb devices shouldn't have same vendor/product ID and same serial

[Sven]

Public bug reported:

Boot Windows XP with
./qemu-system-i386 -device pci-ohci -device usb-tablet
and then with
./qemu-system-i386 -device pci-ohci -device usb-kbd

and you will notice, that the usb keyboard is not detected. In fact,
Windows XP detects the usb tablet and loads the driver for the tablet
instead of the driver for the keyboard.

The problem seems to be, that vendor and product ID and even the seriel
of both the usb tablet and the usb keyboard are the same as an lsusb
reveiles. Hence, Windows XP doesn't detect when you replace the tablet
by a keyboard and vice versa. I didn't check other USB devices, but it
seems a bad idea to me to have devices with the same vendor/product Id.
I'm not aware, whether it is sufficient to change the seriel numbers of
the devices.

This is a problem with ancient Linux distributions that match vendor-
product in Xorg.conf as well.

This bug is more than 4 years old. Why did I even bother writing it? Is
the problem still there in recent qemu versions?

[Dr. David Alan Gilbert]

Hi Sven,
  Hmm you do have a point - I wonder if this is fixed on windows by commit 5319dc7 from Gerd in November 2013 that added 'msos-desc' compat properties; but I see your point about having the same IDs

Try "-device usb-tablet,serial=1234"

[Michal Suchanek]

I see no option in Xorg.conf to match serial. Maybe there is. It is
mostly undocumented, especially for some random ancient X11 snapshot the
distro has.

That said the VM happens to be configured in such a way it works -
keyboard and mouse are in same order on USB bus and in Xorg.conf
