A method to interact with a local USB device is disclosed. Messages are transmitted to a remote host controller driver from a host controller associated with the local USB device. Messages are received from the remote host controller driver for the host controller. In some embodiments, a transfer descriptor prototype is received from the remote host controller driver. A completed transfer descriptor is received from the remote host controller driver. The completed transfer descriptor and the transfer descriptor prototype are transformed into a modified transfer descriptor in part by using a collection of rules. The modified transfer descriptor is submitted to the local host controller without intervention from the remote host controller driver.
