Abstract: Methods and systems described herein facilitate improving universal serial bus (USB) storage performance in remote computing environments. A virtual USB host is associated with a virtual machine running a guest operating system (OS) and is configured to communicate with a USB storage device that is connected to a remote terminal. The virtual USB host is further configured to transmit one of a data-in request to the USB storage device before the guest OS transmits the data-in request or an acknowledgement of a data-out request to the guest OS before the USB storage device transmits the acknowledgement.
