Implementations of the present disclosure provide methods and systems for identifying peripheral devices with which problematic connections have been established. According to one embodiment, a method for detecting a model of peripheral device for which problematic connections with a computerized unit are common is disclosed. The method involves receiving values of each of one or more features of a particular connection between a computerized unit and a peripheral device, using the received values to determine a score for each of the features of the particular connection, calculating an overall connection score from the scores for each of the features, and generating a problematic peripheral device report including the model of the peripheral device if the overall connection score is indicative of a problematic connection.
