VID/PID TUSB9260

Other Parts Discussed in Thread: TUSB9260, TUSB9261

I have designed into my board the TUSB9260. I have programmed it with the TI firmware and it does show up as a mass storage device. It seems to work properly. My question is about the VID/PID. Currently it is 0x0541/0x9260 which I assume belongs to TI. Do we need to obtain our own VID from the USB org or can we continue to use 0x0541? If we get our own VID how do I change it? Will the device still enumerate as a mass storage device?

    Travis,

    Before I answer your question on VID/PID, I'd like to point out that we have a 2nd generation USB-to-SATA bridge, the TUSB9261.  While it is not a direct drop in replacement, it does fix errata present in the TUSB9260 as well as removing the requirement for one of the external voltage supplies.  As I said, it is not s direct drop-in, so please refer to the TUSB9261 Implementation Guide if you are change.

    While the recommendation is to get your own VID and assign your own PID.    That way the end customer will see that the product is yours and not TIs if they take the time to  "look" at the info in device manager.

    Changes to the descriptor can be implemented using our Flash Burner Utility - you can see the User's Guide section 4.3 that  talks about editing descriptors.  The mass storgae declaration is one of the items in the descriptor.
