Part Number: TUSB4041I

Hi! i want to use TUSB4041 for HUB. I'm new for this controller

1. When I try without EEPROM, Do I need program for TUSB4041I?

2. If I use EEPROM, How can I program (byte code structure) ?

3. Do you have programming tool for this controller?

Thanks

Hi Wson,

You can use this document as a guide for creating the EEPROM file - register settings will vary slightly for the TUSB4041 device, please check with the datasheet.

I understand that I can use TUSB4041 without programming (without EEPROM), and when I want to setup register in TUSB4041, I need EEPROM. Is it right?

Thanks.. I got the tools.

After connect usb device, How I can check usb speed ? I want high speed (488 mbps) for gauge data transfer.

You can download the usbview.exe tool from Microsoft which reports bus speed.
