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

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.
