TUSB9261DEMO for a USB Hard Drive for SATA boot

Other Parts Discussed in Thread: TUSB9261, TUSB9261DEMO

Hi TI,

  I have an application where I'm trying to have a USB hard drive communicate through my SATA port on my carrier board.  The idea is that my carrier board will boot using its SATA connector, which is connected to the TUSB9261 that will hopefully communicate with the USB hard drive.

  From what I read from the TUSB9261DEMO implementation and User's Guide, my application is backwards from the typical implementation.  Can the TUSB9261DEMO communicate to a USB hard drive and bridge to SATA to boot?

Thanks

    Hello Kentin,

    That isn't possible to implement neither using the TUSB9261 nor any other USB to SATA bridge in the market.

    In order to enumerate your USB hard drive, you need to connect it to a USB Host Controller. The USB interface on a "USB to SATA" bridge is designed to operate as a device, not as a USB host.
