This web page refers to our older busTRACE 6.0 which is no longer shipping. Click here for details on our latest busTRACE version.

busTRACE 6.0 includes the ability to scan for certain software defects in the data structures that we capture. This is different than the defects we can detect and report in Command Descriptor Blocks. This feature is currently limited to analyzing SCSI Request Blocks as well as SCSI Pass Through requests.

In this sample screenshot, software has issued a Test Unit Ready CDB with an expected inbound data buffer. The Test Unit Ready CDB does not transfer data thus the direction bit should have been set to IOCTL_DATA_UNSPECIFIED with a zero length data transfer length.

This feature allows software developers to fix common software bugs and make for a more robust software application.
