usbFindDevice():get usb device according to
idVendor, idProduct, bus, device
it is the exact match of the four parameters
usbFindDeviceByBus():get usb device according to bus, device
it returns only one usb device same as usbFindDevice
usbFindDeviceByVendor():get usb device according to idVendor,idProduct
it probably returns multiple usb devices.
usbDeviceSearch(): a helper function to do the actual search

This patch doesn't even compile!
qemu/qemu_hostdev.c: In function 'qemuPrepareHostdevUSBDevices':
qemu/qemu_hostdev.c:599:33: error: too few arguments to function
'usbFindDevice'

You can't change the signature of usbFindDevice unless you update all
callers in the same patch.
I compiled it and tested it , then sent it out.
I think the changes on usbFindDevice caller is in PATCH2/3 and PATCH 3/3
"usb = usbFindDevice(vendor, product, bus, device);" are there.
No, every patch shouldn't break the build. You have to update
all callers of usbFindDevice together with this patch.
