I purchased a Sony T-1 and now my daughter's 300 is recognized by the Reader software but not Calibre. I made sure it was authorized and everything is the current upgrade - here is the debug log - thanks!
Edited: After launching Reader software again, it is now detecting it. I will report if bug reoccurs.
