Mouse and keyboard not working in qemu emulation of beagleboard with latest angstrom image

Question

I was trying to emulate an angstrom image for beaglexm in qemu on my Ubuntu 12.04 laptop. In a new window the image boots up and autologins into GNOME shell. But keyboard and mouse remains unresponsive.

I gave the following command:

qemu-system-arm -M beaglexm -m 1024 -sd Angstrom-TI-GNOME-image-eglibc-ipk-v2012.01-core-beagleboard-2012.01.11.img -clock unix -serial stdio -device usb-mouse -device usb-kbd -net nic -net user,hostfwd=::2222-:22

As the emulation starts, following log is generated on the parent terminal

Warning: vlan 0 with no nics

After the image completely boots up into shell, the keystroke is not responsive but logs the following in the parent terminal:

usb-kbd: warning: key event queue full

I tried a solution given here by building latest linaro-qemu from scratch but same result.

Also I am not able to ssh into this running image. I issued the following command

ssh -p 2222 root@localhost

It is simply refusing the connection

The reason for this unresponsive keyboard and mouse is that, you need to specify host's USB bus number with device number for USB Pass-Through.

$ lsusb enter image description here

My keyboard bus number is 002 and address is 001. So, change your command based on your device number and address.

Assuming the same keyboard number and address, your command will be as follows:

qemu-system-arm -M beaglexm -m 1024 -sd Angstrom-TI-GNOME-image-eglibc-ipk-v2012.01-core-beagleboard-2012.01.11.img -clock unix -serial stdio -serial stdio -usb -device usb-host,hostbus=2,hostaddr=1

Add your mouse in the same way as keyboard. If there is no cursor pointer you can add -show-cursor to your command.
