+<PRE>On the bugzilla website when filing a new bug, the choices are:
+
+Installer
+New RPM Package Request
+RPM Packages
+Release (media or process)
+Security
+
+How do I file a hardware related bug?
+
+I have a Sennheiser DW Pro 1 dect headset which supports USB to PC:
+<A HREF="http://www.sennheiser.com/sennheiser/home_en.nsf/root/private_headsets_office_wireless-series_504304">http://www.sennheiser.com/sennheiser/home_en.nsf/root/private_headsets_office_wireless-series_504304</A>
+
+When I try and use it under latest Cauldron - the system freezes (mouse
+moves but can't do anything else) - when I disconnect it (switch to
+telephone side - the system responds again. No error messages etc.
+
+I have tested this under Ubuntu 11.10 and Mint 12 which do not have the
+hanging problem - the USB audio device works (but the microphone is REAL
+quiet)
+
+So something is wrong with our kernel (I suspect):
