Abstract:
Methods and systems for conducting a transaction between a virtual USB device driver and a USB device client are provided. A hypervisor of a computer system receives one or more data packets from the client. The hypervisor stores the one or more data packets in a buffer. The hypervisor dequeues a data packet from the buffer. The hypervisor transmits the data packet to the virtual USB device driver.
