No UHD Devices found in Parallel Ubuntu Linux

The B200 works with out any problems if connected directly to the MAC
OS, but a new ubuntu 14.04 install on parallels does not recognize the
hardware:

[email protected]:/usr/bin# uhd_find_devices
linux; GNU C++ version 4.8.2; Boost_105400;
UHD_003.005.004-140-gfb32ed16

No UHD Devices Found

[email protected]:/usr/bin# dpkg -l | grep uhd
ii libgnuradio-uhd3.7.2.1:amd64 3.7.2.1-5
amd64 gnuradio universal hardware driver functions
ii libuhd003:amd64 3.5.5-1
amd64 universal hardware driver for Ettus R. products
ii uhd-host 3.5.5-1
amd64 universal hardware driver for Ettus R. products

Also, dmesg reports this as follows:

[ 124.884256] usb 1-2: new high-speed USB device number 3 using
ehci-pci
[ 125.017856] usb 1-2: New USB device found, idVendor=2500,
idProduct=0020
[ 125.017859] usb 1-2: New USB device strings: Mfr=1, Product=2,

[ 125.017861] usb 1-2: Manufacturer: Cypress
[ 125.017862] usb 1-2: SerialNumber: 0000000004BE

I read some posts about similar issues but those were very old and with
the USRP1 devices.

Has anyone got this running with a virtual linux install?

Thanks

Am able to access the B200 now. Noticed that the uhd driver version was
UHD_003.005.004-140-gfb32ed16. Uninstalled this and downloaded the
latest 007 version and reinstalled. Now uhd_find_devices is finding the
B200.

Thanks
Hari

Next hurdle:

at /opt/uhd-git/host/lib/usrp/cores/radio_ctrl_core_3000.cpp:228

No clue what this is, not sure how to go about fixing this.

Greatly appreciate any help with this.

Thanks
Hari
