Linux/TUSB4041I: USB2.0 compliance test

user1492423
Prodigy 50 points
Part Number: TUSB4041I

Tool/software: Linux

The TUSB4041I upstream is an ARM SoC with Linux OS and  downstream are two USB2.0 ports.
I want to do the compliance test of downstream.

I know that USB-IF has USBHSET test program with Windows OS.
This program can set the TUSB4041I to several compliance test modes.
Does USB-IF have USBHSET test program with Linux OS?
If not, I want to know how to output TEST_PACKET in other ways.
Does TUSB4041I have special registers to output TEST PACKET by SMBUS control?

    Hi,

    The TUSB4041 requires a USB host to send the commands described in the USB 2.0 specification in order to generate the test packets. The USB-IF does not provide any Linux tools. There is some information online on generating the test packets with Linux, but TI does not have a driver or utility available.

    Regards,

    Hi JMMN,

    Does TUSB4041 have special registers to output TEST PACKET by SMBUS control?
    If not, is there the method to output Test_packet other than "information online on generating the test packets with Linux"?

    Best regard,

    The TUSB4041 can only generate the test packets if sent the proper USB commands by the USB host, there is no way to force it through register accesses.
