ABSTRACT:
A universal serial bus controller pre-generates and stores a subset of USB commands in a memory, the pre-generated commands available for transmission to at least one USB peripheral device over universal serial bus, and transfers at least one command from the subset of pre-generated commands stored in the memory to the USB peripheral device over the universal serial bus. The universal serial bus controller may receive a response to the transferred command from the USB peripheral device over the universal serial bus, and send an acknowledgment packet to the USB peripheral device over the universal serial bus responsive to receiving the response from the USB peripheral device.
