[Qemu-devel] BUG: 0.14.0 -device usb-host supports only one device

[Erik Rull]

When enabling the -device usb-host option support for adding automatically 
USB devices from the host to the guest, only one device gets detected.
It does not matter if it is added via commandline or via device_add on the 
qemu console.

Curious: If a second devices is plugged into the host, nothing happens in 
qemu. But on the host, the device is detected. If the first device is 
removed, the second device gets detected by qemu. If then the first device 
is added again, it gets not detected by qemu until the second device is 
removed and so on.

When adding the devices manually, everything is fine.
Confirmed with and without the ehci-patch on qemu-kvm 0.14.0. I first sent 
the report to the kvm list but it seems to be a pure qemu related issue.

Best regards,

Erik
