Other Parts Discussed in Thread: TUSB3410

 

Hello every body.

 

Every Time when i attache TUSB3410 with my PC's any USB Port, It give me the same comport No., i.e (Com5).

And when I connect two TUSB3410 devices at separate USB Ports, It give errors.

I want that when I change the USB Port for my TUSB3410 Device, Comport No. also Change.

So that I can connect more than one TUSB3410 devices at a time with my PC.

    Hello,

     

    When a TUSB3410 has an EEPROM, and it has been 'serialized', it is expected to have the same COM port for that device.

     

    On the contrary, if you don't have an EEPROM or even if it exists and it has not been serialized, then you will find that the COM port number will change depending on the USB port you plug the device.

     

    If you want to connect two or more devices at the same time, then I suggest to have different serial numbers for each 3410 device. The OS will assign a unique COM port number depending on the serial number you gave inside the EEPROM. Please note that if serial numbers and descriptors are equal between two or more 3410 devices, the OS won't be able to detect them properly.

    I hope this helps.
