Hi,

I'm using the TUSB9261 to interface an SSD disk with a 4-port USB 2.0 Hub, however the device doesn't seems to respond.

Attached you can find my schematic, is anything wrong with it?

Thank you.

Hello,
The TUSB9261 requires an external EEPROM to load the firmware, you can download the firmware and a windows GUI (flash burner) to program the firmware in the attached SPI EEPROM.
You also have to connect the GRST# terminal per datasheet requirement.
Please take a look to the Implementation guide for a reference schematic, here www.ti.com/.../slla315

Hi Elias,

Thank you for your reply.

I thought that the EEPROM was optional if we wanted to change the default configurations.

Is there a list of supported EEPROM's that work with the device? Because on the datasheet there's a reference to a Table that has that information but that Table doesn't exist... :-)

Thank you.
