About EEPROM and FX2(68013a) USB interface in USRP

Hi All

I am developing a board with gnuradio which is like USRP. It is also use
FX2LP(CY7C68013a) and AD9862, and I add some surroundings.

I hope that my board can work well with gnuradio, but it seems like it
can
only support USRP now. So could you please give me some help, if I want
to
run gnuradio on my board. How should I do with it?

Now I do some test with my board.

When I plug the board to host and run command : lsusb
the information list as below:

Bus 002 Device 003: ID 0b4:8613 Cypress Semiconductor corp. CY7C68013
EZ-USB
FX2 USB 2.0 Development Kit

When I plug the USRP it shows
Bus 002 Device 003: ID 0xfffe:0x0002

My board is recognized by PC, but VID and PID is different from USRP.
What’s the problem with it?
It means the driver(s) is not correct? Or I should change something in
the
source or head file?

PS: I don’t configuration EEPROM with CY7C68013a now. Does this cause
some
issues? Should I leave it blank? If not, what and how should I burn in
it?

When I run benchmark_rx.py, it shows “Fail to automatically setup a usrp
device”.
I think it make sense, because the PC doesn’t find USRP anyway.

Thank you guys all!!

Best Regard
Sindy

Your questions reveal that you don’t know have much of an
understanding of USB. If you hope to create a USB based device,
you should probably spend some time studying the USB 2.0 specs.

Thank you very much, Eric!

I konw it is the USB issue, and I am really a greenhand in this area. I
have
learned how to change PID/VID via EEPROM and how to burn program in it
now.

And my question is which source code is the content of the EEPROM in
gnuradio, that I can burn it in? it should be a data file in the
package,
right?

Thank you again!
