TUSB2046B: Detect the physical port of a connected device in windows.

Part Number: TUSB2046B

Hi! 

I'm working on a PCB which has one USB-B port and four USB data loggers. In order to get the data out, I intend to connect all of the data loggers to a TUSB2046B hub.

I was wondering whether there's any simple way in windows to find out which data logger is connected to which physical port of the USB hub.

Without this, it becomes much harder to know which data is coming from which logger as COM port assignment seems to be random. 

Any help would be greatly appreciated. 

Cheers, 

Giorgos

    Hello Giogors,

    At the hub detection, the USB host will always assign the same port number that corresponds with the physical port number. Therefore, you should be able to access the Windows registry of your system to know which COM is attached at a specific port.

    I suggest using usbview utility to get more information about the hub and device. Select the item in the left window will allow its descriptors to be read in the right window.

    Regards
