usb in qemu
 
How do I actually connect my USB flash to qemu? Documentation says I have to supply qemu with -usbdevice host:bus.addr or -usbdevice host:vendor_id:product_id, but how do I know all these host:bus.addr?

Use the command lsusb, this list USB devices connected. If you're running with the option --verbose will show you additional information as idVendor, idProduct among others...

Code:
# lsusb
Bus 3 Device 1: ID 0000:0000
Bus 5 Device 1: ID 0000:0000
Bus 1 Device 2: ID 0457:0151 Silicon Integrated Systems Corp. Super Flash 1GB Flash Drive
Bus 1 Device 1: ID 0000:0000
Bus 4 Device 1: ID 0000:0000
Bus 2 Device 1: ID 0000:0000
Code:
# lsusb -v

If you have a bootable image on the flash memory, the command is
#qemu -usb /dev/sdX
To find the actual name of "sdX" please do
#fdisk -l
