Title: DSO2D15 Suggest adding decode for USB 2.0 [Print this page] Author: BufordTJustice Time: 2023-9-22 19:50 Title: 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. Author: kevinmartin Time: 2024-2-7 20:23
