FYI,I just hit this issue with windows guests.linux guests works well also, i boot a guest with 1.0 controller: /usr/libexec/qemu-kvm -usb -device usb-host,hostbus=2,hostaddr=2,id=hostdev1 dmesg on host: JBD2: I/O error detected when updating journal superblock for sdb1-8. Aborting journal on device sdb1-8. JBD2: I/O error detected when updating journal superblock for sdb1-8. journal commit I/O error EXT4-fs error (device sdb1): ext4_put_super: Couldn't clean up the journal EXT4-fs (sdb1): Remounting filesystem read-only Win7 guest works fine, on WinXP the issue reproduces. Will look into it. Patch posted. Reproduced with qemu-kvm-0.12.1.2-2.209.el6.x86_64
1. boot a Windows guest with a passthrough usb stick
