There is a potential issue with the RaSCSI board versions 2.4 and 2.5 when it is assembled with the DB-25 connector. If you are installing the DB-25 connector on your board, it is highly recommended that you make a small "cut" on your board. Over time, it appears that the DB-25 shield will wear through the solder mask and may come into contact with the 5v signal right below it. This essentially shorts 5v to Ground. Making this small cut will prevent this from happening.
