TUSB7320: General Query

Part Number: TUSB7320
Other Parts Discussed in Thread: TUSB7340

Hi,

I am looking at PCIe to USB bridge, then I found TUSB7320, I have few queries about this device, can you please clarify.

1. Would it be possible to change the PCIe Gen 2 port as Down stream port(root mode)?

2.And is it possible to Change USB ports as Upstream ports (Slave device).

 Basically I am looking for device bridge between USB 2.0 upstream port(slave) to PCIe gen2 downstream port(Root mode), please let me know  TUSB7320 can support this configuration, if not please suggest any other chip would support this configuration.

Regards,

Venkat
