Problem with BeagleBone V5/Angstrom v2012.05 and CSR Bluetooth Dongle

Hi,

I just upgrade the image of the BeagleBone to the latest Angstrom v2012.05 but my CSR Bluetooth Dongle stopped working. The dongle works fine with previous 2012.01 version of Angstrom. I am pretty new to all these. Any pointer to how to solve this are greatly appreciated.

in 2012.01
