Part Number: TUSB3410

Hi sir,

My customer would like to confirm when using TUSB3410RHBR driver based on centOS 8.0 kernel 4.18.0-80.el8.x86_64 version, is it possible to see the error in below?

ti_usb_3410_5052: probe of 1-1:1.0 failed with error -71DMESG

Thank you.

    "-71" means "protocol error", which can be caused by all sorts of firmware or hardware problems.

    The only way to find the source of the error is to systematically try different devices, cables, and hosts.

    Hi Clemens,

    Complete Dmesg shows ti_download_firmware  - error, so is this caused by firmware?

    After the firmware has been downloaded, the device resets itself (which disconnects it from the bus), and then reconnects with its new identity. Apparently, when the driver tells the device to reset, the device does not send back an answer because it is already resetting.

    So if you get a working device after that "disconnect" message, then everything is fine.

    Hi Clemens,

    So is that mean we can neglect these errors?

    Thank you.

    Yes, this message alone is harmless.
