How to capture data

Do you want to look through data and data packets your computer and USB device exchange between each other?


Step 1.


To be able to capture data, make sure the following three conditions are observed:


1.Your device must be connected to a USB port. If the device is not connected yet, connect it now to any available USB port;

2.Your device must be correctly initialized and installed in Windows. If the device is not recognized or initialized in Windows (the icon of the device in the list of devices in the program is either unknown or notconnected), you should contact the device manufacturer in order to get the new version of the driver or instructions on how to install the device. You may have to restart the computer;

3.Our filter driver must be installed for your device, either as the class filter or as the device filter. If you have not done anything with the driver after its installation (and have not forgotten to restart the computer after you installed the program), you do not need to do anything. Otherwise use the driver control commands to install it in the system.


Step 2.


Use one of the three methods described in the "User interface" section to open the Monitor window.


Step 3.


Use the "Filter" button to specify your custom filter parameters. If you do not know what filter parameters mean, it is recommended to enable all the options.


Step 4.


If you want to create a log file with captured data, click the imp_exp_bin16 button and specify a name for the log file if the program offers you to do it.


Step 5.


Click the "Start" play_blue16 button to start capturing data. Click this button once again to stop capturing data. If your device works correctly, but there is no data in the Monitor window, you should:


Make sure all conditions in step 1 are observed.

Make sure all filter options are enabled.

Make sure your device sends or receives some data. Most USB devices are constantly informing the computer about their status. If your device is an exception, you should generate traffic for it. To do it, just use the device in a usual way (if it is a mouse, move it; if it is a sound card, play a sound via it; if it is a USB drive, write a file to the drive or read a file from it, etc.).


If you still cannot see any data, see the "Troubleshooting" section or contact our technical support service at support@aggsoft.com.
