USB Hub with microSD - which TI devices are suitable?

Other Parts Discussed in Thread: TUSB8041A

My customer wants to implement a very simple USB Hub that allows to connect a microSD card between a Host PC and a peripheral. The Hub does not need any intelligence, the Host PC should see the microSD card and the peripheral device as separate devices. So the Hub would just have 3 connectors: USB-A, USB-B and microSD.

Question: Which TI devices are suited to implement such functionality most effectively?

Thanks

    Hi Josef,

    Unfortunately this is not so simple. TI does have USB Hubs (TUSB4041 or TUSB8041A) for this application but we do nor have any USB Hubs that has native microSD support. Another IC would be needed for the microSD (SPI) to USB function. Unfortunately we do not have a SPI to USB solution.
