THAT is exactly it. I think I have a scenario where it happens:
You've done some stuff with usrp so that it and daughter card gets
loaded up.
You finish up, exit, rip out the power cable, plug in the power again
and the usrp USB gets re-registered.
Then, (with the verbose flag turned on) I see th

Every time you instantiate a usrp source or sink it checks to see if
it needs firmware and/or an fpga bitstream. The library code checks
two MD5 hashes that are stored in the FX2 ram, o
When you unplug, are you unplugging from power and/or the usb?
Hard to say, I believe I have done both. However, I haven't been able to
piece together an exact set of circumstances that lead to this problem.
Sometimes it happens, sometimes not is about the best that I can say for
now. ;) I'

I am now seeing something like this one crop up, very annoying.
Basically, I'm running in RX mode for a while. I stop running. I may
unplug usrp, plug it in. Then:
usrp: found usrp rev2
usrp_open_interface:usb_claim_interface: failed interface 2
could not claim interface 2: N

Are you physically plugged into a USB 2.0 port?
A system may have multiple of USB ports, but not all of them are 2.0.
Many will be USB 1.1 (high-speed 12mbps) devices.
If you run usbtree, you can verify your connection. The following is an

Hi -
I have an Avnet Virtex 4 evaluation board, intended for
projects similar in concept to GNU Radio. It uses the
same CY7C68013 chip as USRP.
I used USRP as a software reference design, and started
splicing in some code of my own. I think that part is
in good shape, after coming up to speed o
