Hello,
I’ve problem with USRP. Since I’ve upgraded my Ubuntu to 9.0.4 - usrp
doesn’t work:
/usr/local/share/gnuradio/examples/usrp/usrp_benchmark_usb.py
Exception RuntimeError: ‘maximum recursion depth exceeded while calling
a
Python object’ in <type ‘exceptions.AttributeError’> ignored

When I connect USRP, I get this:

And lsusb shows me:
Bus 007 Device 028: ID 04b4:8613 Cypress Semiconductor Corp. CY7C68013
EZ-USB FX2 USB 2.0 Development Kit
But if I connect High Speed Hub to the same port, I get this:
usb 2-3: new high speed USB device using ehci_hcd and address 34
usb 2-3: configuration #1 chosen from 1 choice
hub 2-3:1.0: USB hub found

So is it ok with usrp’s USB controller?
Can you please help me?
Thanks in advance
