TUSB4041I: Illegal periodic small pulse on D-

msmn
Intellectual 805 points

Part Number: TUSB4041I

USB Host <--> TUSB4041I <--> USB Device

When a customer performed data communication between USB host and USB device for a long time, the connection between USB host and TUSB4041I was terminated.

When this problem happened, 3.3V was seen on D+ and illegal periodic small pulse was seen on D-.

I want to send the waveform and the schematic. So please let me send them through your private message.

Regards

msmn
