DSO2D15 Suggest adding decode for USB 2.0
I have a DSO2D15 and would like to know to decode USB2.0 low-speed and full-speed.With high-speed USB 2.0 being 480Mbit/s this may not be possible for this scope.The data being sent over the USB cable to a Microcom printer is a barcode and about six words.I have spliced into the USB cable so I could attach probes.I have probe 1 connected to the D+ and probe 2 connected to the D- of a USB cable.I can see data on both probes being continuously sent.I can print as before, but have not found a way to trigger on the data being sent when I press the print command.IIC decode came the closest to displaying what I wanted.The USB 20.pdf shows PID types that I hope to sync off of.They can be found at http://www.poweredusb.org/pdf/usb20.pdf, page 196, chapter 8 protocol layer.Thank you for your consideration and suggestions.The DSO2D15 is a digital oscilloscope with a bandwidth of 200 MHz and a maximum sample rate of 1 GS/s. It has two channels and a maximum record length of 10 Mpts.
