** Description changed: + SRU justification: + 1. Impact: USB devices which use large control buffers (like some PDAs) cannot be used with a VM. + 2. How bug was addressed: A one-line patch was taken from upstream, increasing the size of the control buffer. + 3. patch: see patch in the description + 4. TEST CASE: connect a usb device which uses control buffers > 2k. + 5. Regression potential: the size of a buffer is increased, with no other changes. The only potential for regression, therefore, would be due to kvm consuming more memory. + Binary package hint: qemu-kvm I would like to connect my PDA to kvm virtual machine with the following command: kvm -m 1024 -k hu -usb --usbdevice host:2.4 VM.img It finds my USB device, but after throws: husb: 2 interfaces claimed for configuration 1 husb: grabbed usb device 2.4 husb: config #1 need 1 husb: 2 interfaces claimed for configuration 1 husb: config #1 need 1 husb: 2 interfaces claimed for configuration 1 husb: config #1 need 1 husb: 2 interfaces claimed for configuration 1 husb: config #1 need 1 husb: 2 interfaces claimed for configuration 1 husb: config #1 need 1 husb: 2 interfaces claimed for configuration 1 husb: config #1 need 1 husb: 2 interfaces claimed for configuration 1 husb: ctrl buffer too small (4104 > 2048) VM starts but without USB device. :-( I've found similar problem on Redhat bugs, and they solved it with a patch. https://bugzilla.redhat.com/show_bug.cgi?id=672720 thx ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: kvm 1:84+dfsg-0ubuntu16+0.12.3+noroms+0ubuntu9.7 ProcVersionSignature: Ubuntu 2.6.32-30.59-generic 2.6.32.29+drm33.13 Uname: Linux 2.6.32-30-generic i686 Architecture: i386 Date: Mon May 30 11:56:40 2011 InstallationMedia: Ubuntu 10.04.1 LTS "Lucid Lynx" - Release i386 (20100816.1) KvmCmdLine: Error: command ['ps', '-C', 'kvm', '-F'] failed with exit code 1: UID PID PPID C SZ RSS PSR STIME TTY TIME CMD Lsusb: - Bus 002 Device 003: ID 046d:c312 Logitech, Inc.
