[Discuss-gnuradio] Full duplex on USB connections?

[Yong J. Chang]

Hi all,

Since I'm not familiar with USB architecture, it might seem like stupid
question.
Now I'm receiving some data(called RxData) from USRP and obviously USRP is
set as a receiver mode. At the same time, I have a data to be
transmitted(called TxData) which is not related with received data. The flow
is that I recognize the end of packet from RxData and manually switch the
USRP as a transmit mode. After that, I send TxData to USRP. 

As I know, USRP is using EP2 and EP6 as OUT and IN port respectively and
each port is half duplex line. Is it mean that I cannot receive data stream
from USRP and simultaneouly send data into TXFIFO on FPGA? 

I just want to reduce delay between end of received packet and start of
transmit some other packet. 

If possible, I want to fill the TXFIFO simultaneously during receiving data
from USRP and quickly switch USRP to a transmitter. 

Is there any suggetions of reducing delay between receiver and transmitter? 

Thanks in advance!
