A method includes generating trace data at a device associated with data communication to and from a computer storage device through an appropriate communication link therefor and transmitting the trace data through the appropriate communication link. The trace data is configured to enable debugging of a set of instructions associated with the device. The method also includes capturing the trace data transmitted through the appropriate communication link through a protocol analyzer, a host system or the protocol analyzer coupled to the host system and analyzing the trace data therein to obtain information associated with the set of instructions associated with the device. The protocol analyzer, the host system or the protocol analyzer coupled to the host system is configured to be external to the device associated with the data communication to and from the computer storage device.
