TUSB2136 USB packet sniffer

Gianluca Fares

Hi,

Is not clear to me if the MCU in the TUSB2136 can be used as USB packet sniffer. In the TUSB2136 firmware programming flow doc, http://www.ti.com/lit/ug/sllu020a/sllu020a.pdf, seems it can be done using Interrupt notification but I'm not 100% sure.

Can someone help me ?

Thanks in advance

Hello,

I have received confirmation that it is not possible to implement a USB sniffer with this device.

Dear Elias;
I am planning to use TUSB2136 between PC and a usb device. I need to know that if I could get DIR interrupt by internal 8052 MCU. My aim is if DIR is from PC to TUSB2136 (this mean to the device) ,I need to pull TRIG port of device to high.
