---Problem Description--- When guest OS is started using qemu-kvm command appended with "-usb usbdevice host:<vendorid>:<productid>", the USB passthrough device is not made available to the guest OS. Though qemu-kvm command starts guest OS without any errors, inside the guest OS, "lsusb" command is not listing the passthrough device. Guest OS : SLES11 SP1 64 bit ---uname output--- Linux hostname.in.ibm.com 2.6.32-118.el6.x86_64 #1 SMP Tue Feb 22 11:15:55 EST 2011 x86_64 x86_64 x86_64 GNU/Linux Machine Type = HS22 ---Debugger--- A debugger is not configured ---Steps to Reproduce--- Steps: 1. Started qemu-kvm command appending "-usb usbdevice host:<vendorid>:<productid>". command: /usr/libexec/qemu-kvm -hda ../images/SLES11-SP1-64.raw -m 512 -vnc :9 -usb usbdevice host:04b3:4010 -net nic -net tap,script=../scripts/qemu-ifup 2. Once the guest is started, logged in to the guest and run "lsusb". It is not listing the passthrough device. ---KVM Component Data--- Userspace tool common name: qemu-kvm The userspace tool has the following bit modes: 64 bit Userspace rpm: qemu-kvm-0.12.1.2-2.148.el6.x86_64 =Comment: #1================================================= 1.Server architecture(s) (please list all effected) (x86/POWER6/Z/etc.): x86 2.Server type (9117-MMA/HS20/s390/etc.): HS22 3.General component (desktop/kernel/base OS/dev tools/etc.): virsh 4.Other components involved (ixgbe/java/emulex/etc.): nope 5.Does the server have the latest GA firmware? yep 6.Has the problem been shown to occur on more than one system? yes 7.Is a tested patch available? nope If yes to the above, has it been approved upstream? 8.What is the latest official Red Hat build on which this bug has been seen? 6.1 Alpha
