TUSB3410 Linux Driver?

Other Parts Discussed in Thread: TUSB3410

Hi everyone,

First time posting about TUSB3410. I am trying to connect the usb-serial link to a linux machine. However, dmseg does not link it to a device number. Does anyone know how I go about getting driver support for this? All the information on the internet seems to be for kernel versions 2.6, I am on 3.13.

Many thanks,

    Hello James,

     

    The TUSB3410 is included as default since kernel 2.6.1, so it must be enabled by default on kernel 3.13.

     

    I’m attaching you a quick reference that will help you to enable the TUSB3410 driver in case that it’s not enabled.

    Hi Roberto, Thank you for your fast and detailed reply. How can I tell if its included in the kernel? I setup and the rule as per .doc file but still the dmesg is incorrect. I found the id to be 0x5f00. James.

    Hi everyone, anyone?


    I am still struggling with this.

    Aim: to connect MSP-EXP430F5438A board to Ubuntu 14.04LTS via usb-uart provided. (as you do on windows).

    Progress: I have found that the newer version has a different product id 0xF500. If I use command, sudo modprobe usbserial vendor=0x0451 product=0xF500 then connect the device I get the following in dmesg:

    [11436.797764] usbserial: USB Serial support registered for generic
    [11451.362491] usb 3-2: new full-speed USB device number 9 using xhci_hcd
    [11451.398852] usb 3-2: New USB device found, idVendor=0451, idProduct=f500
    [11451.398862] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
    [11451.398868] usb 3-2: Product: MSP-EXP430F5438
    [11451.398873] usb 3-2: Manufacturer: Texas Instruments
    [11451.398877] usb 3-2: SerialNumber: AFE7894604000F00
    [11451.400972] usbserial_generic 3-2:1.0: The "generic" usb-serial driver is only for testing and one-off prototypes.
    [11451.400991] usbserial_generic 3-2:1.0: Tell linux-usb@vger.kernel.org to add your device to a proper driver.
    [11451.401006] usbserial_generic 3-2:1.0: generic converter detected
    [11451.401261] usb 3-2: generic converter now attached to ttyUSB0

    This is better as before I wasn't getting ttyUSB0. However is this correct - should it not be the ti_usb_3410_5052 driver? I ask, because if I use Python or Miniterm I see nothing (not even on the scope).

    Hi Roberto,


    Not the most helpful reply.

    I have now figured this out - difficult when google is full of rather old fixes.

    Indeed what we expect to happen in the correct system is:

    [  937.271758] xhci_hcd 0000:00:14.0: xHCI xhci_drop_endpoint called with disabled ep ffff880036a44a00
    [  937.436562] usb 3-2: new full-speed USB device number 6 using xhci_hcd
    [  937.497688] usb 3-2: New USB device found, idVendor=0451, idProduct=f500
    [  937.497700] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
    [  937.497705] usb 3-2: Product: MSP-EXP430F5438
    [  937.497710] usb 3-2: Manufacturer: Texas Instruments
    [  937.497714] usb 3-2: SerialNumber: AFE7894604000F00
    [  937.499465] ti_usb_3410_5052 3-2:1.0: TI USB 3410 1 port adapter converter detected
    [  937.499526] ti_usb_3410_5052: probe of 3-2:1.0 failed with error -5
    [  937.501455] ti_usb_3410_5052 3-2:2.0: TI USB 3410 1 port adapter converter detected
    [  937.501820] usb 3-2: TI USB 3410 1 port adapter converter now attached to ttyUSB0

    i.e. we want the ti_usb_3410 to pick up the msp-430f5438a which has the tusb3410. HOWEVER the newer tusb3410 on the msp5438a boards have a different ID which isn't hardcoded in the driver - 0xf500.

    To fix this, you would normally modprobe with the product ID and vendor ID. HOWEVER in 2013 this was changed to:


    "

    Remove the vendor and product module parameters which were added a long
time ago when we did not have the dynamic sysfs interface to add
new device ids (and which isn't limited to five new vid/pid pair).

A vid/pid pair can be added dynamically using sysfs, for example:

  echo 0451 1234 >/sys/bus/usb-serial/drivers/ti_usb_3410_5052_1/new_id

for 1-port adapters, or

  echo 0451 1234 >/sys/bus/usb-serial/drivers/ti_usb_3410_5052_2/new_id

for 2-port adapters.

    "

    So to add the new ID so the driver picks the device up is:
    sudo su (need to be root!)
    sudo echo 0451 F500 > /sys/bus/usb-serial/drivers/ti_usb_3410_5052_1/new_id 

    remember to add this at boot-up
