Just confirming the bug. I'm having the same issues with the same USB smart card reader as the submitter (Kobil mIDentity) on Debian Squeeze using the qemu-kvm version 1.2.0 from debian-backports. Going back to 1.0 fixes the problem (http://snapshot.debian.org/package/qemu- kvm/1.0%2Bdfsg-8~bpo60%2B1).
Since I can easily toggle between versions i could provide more support, if wanted and instructions provided... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1033727 Title: USB passthrough doesn't work anymore with qemu-kvm 1.1.1 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1033727/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
