Systems and methods for assisting multiple protocol conversion in a network accelerator. A network device includes a transmit processing engine, a receive processing engine and one or more memories, each memory including one or more buffers for storing packets. When a packet is received, the receive engine adds a 4, 8, 12 or 16-byte tag to the front of the packet on a per-VC basis and stores the packet to a buffer. Additionally, the receive engine is able to add an offset to the starting address of the packet in the buffer relative to the beginning of the buffer. When a packet is to be transmitted, the transmit engine is able to transmit the packet from an address that is offset from the starting address of the buffer by one or more bytes. Additionally, the transmit engine is able to add one of several predefined packet headers on a per-packet basis.

The method according to claim 7, further comprising a step of: transmitting at least one successive NAK signal to said computer from said second wireless apparatus along said second USB within said response limit until a response is received from said first wireless apparatus. 9. The method according to claim 7, wherein said communication request comprises a request for reading data from said device, further comprising the steps of: receiving data from said first wireless apparatus; transmitting a predetermined packet to said first wireless apparatus in response to receipt of said data; and transmitting said received data along said second USB to said computer. 10. The method according to claim 7, wherein said communication request is for writing data to said device, further comprising transmitting said data to be written with said communication request to said first wireless apparatus. 11. A method for performing wireless universal serial bus (USB) communication with a first wireless apparatus by a second wireless apparatus communicating along a USB with a device, comprising the steps for said second wireless apparatus of: receiving a data reading request from said first wireless apparatus; transmitting said read request along said USB to said device; receiving data from said device and buffering said data at said second wireless apparatus; returning a predetermined message to said device in response to receipt of said data; and transmitting said data to said first wireless apparatus. 12. A method for providing wireless universal serial bus (USB) communications for notifying a state change from a first wireless apparatus communicating along a USB with a computer to a second wireless apparatus, comprising the steps of: receiving a first state command from said computer along said USB to said first wireless apparatus; transmitting said first state command to said second wireless apparatus; receiving said first state command at said second wireless apparatus; and transmitting a periodic packet including a state bit that indicates the state of said second wireless apparatus. 13. The method of claim 12 further comprising the steps of: receiving a second state command along said USB from said computer; transmitting said second state command from said first wireless apparatus to said second wireless apparatus; changing the state of said second wireless apparatus; and transmitting a periodic packet including a state bit representing the state change for said second wireless apparatus in response to receipt of said second state command. 14. The method according to claim 13, wherein said predetermined command is one of a port suspend command and a disable command. 15. A wireless device for providing wireless universal serial bus (USB) communications for establishing a connection with a wireless apparatus communicating along a USB with a computer, comprising: a receiving unit for receiving a wireless signal from said wireless apparatus; a transmission unit for transmitting a wireless signal to said wireless apparatus; and a control unit for instructing said transmission unit to transmit a connection request packet, for instructing said transmission unit to transmit a predetermined packet in response to receipt of a connection permission packet by said receiving unit, said connection permission packet including bus information concerning said USB of said computer, and for employing said bus information to perform a setup in response to receipt of a packet by said recei
