Use Both Modes Simultaneously to Catch Hard-to-Find USB Bugs.
We have learned through extensive experience supporting our customers that many problems are most effectively debugged live, using multiple points of observation.


	Outside View Use one instance of FTS4USB and the USB ComProbe to watch the external connection between the device under test and the PC connected to the device.
	Inside View (Spy Mode) Use a second instance of FTS4USB running in Spy mode to see the data that is actually being delivered to the application running on the PC.

Find USB Bugs Where They Hide
In order to fix bugs, you have to be able to observe the complete communication chain. FTS4USB allows you to systematically confirm packet content at the point of origination, and inside your PC where your application receives the information.

Use FTS4USB with Products with Embedded Devices
Use the ComProbe to check embedded USB devices sending and receiving data to and from the microcontroller.
