TUSB217-Q1: Abnormal in Embedded Host High Speed Electrical Test with PID/VID board

zehao chen

Part Number: TUSB217-Q1
Other Parts Discussed in Thread: TUSB217

We did the "embedded host high speed electrical test" according to the following figure. We found that the communication between the embedded host and the PID / vid board was abnormal. I know that there may be others reasons. But I would like to ask whether there is compatibility problem between the embedded host and PID/VID board communication through tusb217-q1?
thanks!

Hi,

There is no known compatibility issues with the PID/VID board to the best of my knowledge. What kind of behavior are you seeing? You will want to ensure that TUSB217 is entering test mode at the appropriate time by monitoring CD and ENA_HS signals.
