In my case it's the SmartCard-Reader that's not working, i.e. the DATEV Sof= tware called "Sicherheitspaket" does not = work. The background process called "SiPaHost.exe" just hangs; any client p= rogram trying to display SmartCard = information does also just hang forever. That behaviour is 100% reproducibl= e and persists over reboots of the Linux host = and/or the Windows guest (Windows XP SP3). I did not try Linux guests. Yesterday, i used git to checkout all qemu-kvm versions from kernel.org and= build Debian packets from it (source kept = vanilla, i just applied the two patches that rename paths from 'qemuXXX' to= 'kvmXXX'). The findings were: - v1.0 -> ok - v1.0.1 -> ok - v1.1.0 -> not ok - v1.1.1 -> not ok - v1.1.2 -> not ok - v1.2.0 -> not ok So far, this is consistent with the findings in this bug report. BUT: The latest HEAD from kernel.org (called "v1.2.50") also does work again! So, i'm now learning about git bisect (however, today i won't have time for this).

This worked fine with every older qemu-kvm version I've used so far. But since 1.1.0 it doesn't work anymore. The device shows up in the guest, but the software can't access it anymor= e (and the guest is pretty unresponsive). On the host I get every 2 seconds this message: [ 7719.239528] usb 6-1: reset full-speed USB device number 2 using uhci_h= cd Command line options are: /usr/bin/kvm ... -device usb-host,vendorid=3D0x0d46,productid=3D0x3003,bus=3Dusb.0,port=3D3 ... When I switch back to qemu-kvm 1.0.1 everything works fine again. Any idea what the problem could be?
