QEMU hardware emulation usually doesn't work at the Linux character device passthrough. In the source tree, look at hw/ which contains the emulated guest devices. These are emulated hardware devices that sit on busses like PCI, not Linux character device passthrough. For example, a real RTL8139 PCI network card is emulated. There is some support for USB device passthrough. If you have a USB webcam (even "internal" webcams are often USB) and Android supports USB webcams, then that might work. It really depends on what webcam devices the Android guest knows how to drive. QEMU either needs to pass through one of those devices or it needs hardware emulation so the guest thinks it is talking to a supported device. Stefan
