Subject: [PATCH] fiddle with printing of "Class of Device" values   - pass the
 class of device octet stream to the function   - only print where the format
 is known (we only know format #0)   - use language from the Baseband Assigned
 numbers document   - use bit numbers from the Baseband Assigned numbers
 document   - add Health device major class

(only these changes this time :)
