[Discuss-gnuradio] USB latency problem

[Rushikesh Khasgiwale]

I tried to use the usrp for implementing rfid protocols, however the USB 
latency is causing a bottleneck and I cannot generate and send the reply 
packet before the timeout(I need to send the reply within 80-120 us).
upon reading Thomas Schimd's 
paper(http://nesl.ee.ucla.edu/document/show/242), it seems that I may have 
to do processing on the fpga itself instead of sending data over usb.

Has anyone else faced a similar problem? CTS packets in 802.11 use 
functionality similar to mine, so maybe those who implemented it can help 
me.

thanks
