My USRP board has developed a USB communications
issue. The host PC no longer responds to the board when the USB
connection is made. USRP does not show up in USBview, and the FPGA does not
load. The green
flashing
LED on the board continues to flash at the faster rate. I can see two
interrupts
using XOSview that are generated when the USB cable is
connected. These results are
from using the Knoppix/USRP live CD on two different computers and with two
different USB2.0 cables.
I am hopeful that this is a firmware instead of a
hardware issue with the USRP USB driver IC. Does the this IC store
its
identification in EEPROM, and can this be reloaded through USB?
Has anyone had a similar issue and
was able to clear the problem?
Thanks for any
help.
