This is strange. On a lark, I right-clicked the unknown tablet device and told Windows to find a driver for it. It told me it couldn't find a better one than what I already had, and then it appeared as a HID- compliant device. Now it works fine!
I'm thinking that what has happened is that some characteristic (name? PCI ID?) of the tablet device changed, and Windows XP doesn't automatically adapt to the "new hardware", but if you fiddle with it, Windows will decide to attach the right driver. It works fine for me now, but that doesn't completely invalidate the bug. At the very least, the bug is that this change wasn't documented well. I tried googling for this, but I found nothing relevant. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/894037 Title: With VNC, "-usbdevice tablet" no longer makes mouse pointers line up Status in QEMU: New Bug description: I use qemu in VNC mode. In order to get the client and server mouse pointers to line up, I've had to use the "-usbdevice tablet" option. This no longer works, and it behaves the same as if the option is not there. This makes my VMs unusable to me. Here's how I'm booting WinXP: qemu-system-x86_64 -vga std -drive cache=writeback,index=0,media=disk,file=winxp.img -k en-us -m 2048 -smp 2 -vnc :3101 -usbdevice tablet -boot c -enable-kvm & The Windows install hasn't changed, only qemu. I'm running this version of QEMU: QEMU emulator version 0.15.0 (qemu-kvm-0.15.0), Copyright (c) 2003-2008 Fabrice Bellard I'll see about upgrading to 0.15.1, but since I haven't seen other reports of this particular problem in your DB, I'm assuming that this problem has not been fixed between 0.15.0 and 0.15.1.
