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: Apr 7 15:00:48 openbts-laptop kernel: [ 4950.513099] usb 2-4: new high speed USB device using ehci_hcd and address 41

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 hub 2-3:1.0: 4 ports detected
So is it ok with usrp's USB controller? Can you please help me?
