   Hi, thanks!   
      
   What I forgot to mention is,   
      
   - I have two of these Jabra headsets   
   - both are new   
   - both behave in the same way   
      
   - upon pluggin in, kernel module 'hid_jabra' is loaded dynamically   
      
   Besides this, I checked for 0 Ohms between headset USB shield and   
   notebook / docking station shield.   
      
   Well, adding signal strength ok on Windows, and specific kernel module   
   loaded, together, it seems to me, that the issue is located in (Ubuntu's   
   and Mageia's) kernel module.   
      
   Any idea what to test next?   
      
   Thanks!   
      
   Best regards,
