   I just set up another Trixie install for a Pi2Bv1.1, so armv7, for   
   use with an Owon vds1022 USB oscilloscope. I have an older install   
   (bookworm) on a separate microSD card which works correctly, but the    
   card is too small (8GB) to allow useful working space. The new install   
   is less than a year newer than the working one.    
      
   The new install allows installation of Florentbr's software found at   
   GitHub but when the software is run it gets stuck in a loop and can't   
   connect to the 'scope:

   that never seems to stop.   
      
   The warning prompted me to try running under sudo, but that made no difference.   
      
   On closer inspection, it's not clear the warning has any relevance to the    
   "device or resource busy" message. Busy isn't the same as restricted.   
      
   If anybody's got a suggestion please post!   
      
   Thanks for reading,
