KVM only supports emulated USB 1.1 at the moment, all USB devices requiring USB 2.0 doesn't work (which includes all iPhones and newer iPods AFAIK). qemu-kvm 0.14 which will be out soon, has received some USB 2.0 patches, but still no initial 2.0 support. Don't expect emulated USB 2.0 support in KVM in CentOS anytime soon. If you have a host with VT-d support, you can try to passthrough one of the USB controllers on your motherboard to a guest - or to add a PCI/PCIe USB card to the host and dedicate it to a guest. I haven't had any luck with ~4-5 different USB controllers/cards, so don't put your expectations too high. Best regards Kenni
