TMS320F28069: USB Interface : Get serial number of connected device

Part Number: TMS320F28069
Other Parts Discussed in Thread: C2000WARE

I develop a product that connects via USB to a desktop PC.

Inside my product, there is a USB hub with three devices connected to it -- one of which is an F28069 microcontroller.

I want to get the serial number of the hub. So, from the F28069 microcontroller, I want to send a command over USB to request the serial number.

Has anyone ever done this before?

    Hi Thomas,

    Our USB software expert is out of office and won't be able to respond until next week. In the meantime, have you reviewed our usb_host SW examples available in C2000WARE? Directory location below:

    Hi, 

    Not sure on how to get the serial number of the hub which is connected but you can get the hub address.

    Referring to the Device TRM , details of the hub address and the hub port  are recorded in the corresponding USB Receive Hub Address Endpoint n  (USBRXHUBADDRn) and USB Receive Hub Port Endpoint n (USBRXHUBPORTn) or the USB Transmit Hub  Address Endpoint n (USBTXHUBADDRn) and USB Transmit Hub Port Endpoint n (USBTXHUBPORTn) registers. 

    Best Regards
