[Bug 790145] [NEW] kvm husb: ctrl buffer too small

[Attb2]

Public bug reported:

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: 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.
