TUSB8041: how to hide "removeble" icon

Hi Ladisch,

May I know how to change the register setting? Use dongle and GUI and change setting online?

Could you please also provide utility and user guide?

Hi David,

I got it, thanks~

Hi,

I've used the tool but fail to change it, could you help to check if any wrong

or can you provide a test F/W for try

Thanks

1.USB Topolgy (we use 3* TUSB8041, and only 1 device need to set as non removable)

2.open the tool but only 1 device can be accessible 

3.we click the non-removable config and program but the device still could be removable

windows server 2022 capture (device still could be removable)

Do you use EEPROM or Efuse? should be EEPROM.

Regards

Brian

yes, we use EEPROM as below, could you help to provide the way to modify EEPROM?

Thanks

Hi, 

I used the EEPROM tool, but it fail to detect the device, could you help to check it, and any guideline for the EEPROM tool?

(TUSB80xx_EEPROM_Programmer_V1.0.0.1)

follow this procedure:

Forcing a USB hub into Programming Mod

e Step 1: Select the USB 2.0 portion of the TUSB8044A hub – it will be the Generic USB hub listed next to the Generic SuperSpeed USB Hub if you set Device Manager to view “Devices By Connection” mode. You can also right click and check the Hardware Ids under Properties, it should be VID_0451&PID_8442. I may have a slightly different version of the silicon, so the PID may be a little different.

Step 2: Once you have the correct Generic USB hub, right click and select “Update Driver Software”, then “Browse my computer for driver software”, then “Let me pick from a list of device drivers on my computer”, and then “Have disk”.

Step 3: When the Install from Disk window pops up, navigate to the TUSB80xx EEPROM Programmer directory (should be under c: Program Files (x86)> Texas Instruments Inc) and select the “TUSB8040.inf” file and open it. Ignore all the warnings and allow the driver to load

Step 4: Open the programming tool. Step 5: You will need to reload the original Generic USB Hub driver after reprogramming the EEPROM

Hi Sinden,
