I have a ".csv" log file that stores the USB logic levels (D+/D- logic levels) of a USB device. The format of the file is listed below :
1.616545667,1,0,0,0,0,0,0,0 1.616545750,1,0,0,0,0,0,0,0 1.616545833,1,0,0,0,0,0,0,0 .....
The 1st column is "time", the 2nd column is logic level of "D+", the 3rd column is the logic level of "D-", the other columns are not used.
I want to know that is there any software (best to be free) that could analyze the ".csv" file and report the "USB requests" that are involved.
In fact, I am debugging a self-made USB device. I could use an USB oscilloscope to log the USB D+/D- levels of the device into a ".csv" file and I want a software that could report to me what was happenning or what was wrong from the ".csv" file.
Thanks in advance for any suggestion.
