FX3 Serial number in Bootloader mode (j4 jumper insert - PMODE)

Hi,

 

I'm using multiple FX3 board devices and I connect them under 4 DS port HUB,

When I restart the computer all off them starting with Yellow Exclamation Mark Issue in Device Manager.

I think it's because when all of the FX3 in Bootloader mode then the Serial number is the same

Serial number "USB\VID_04B4&PID_00F3\0000000004BE"

Can I change the serial number of the  Bootloader mode? I now how to change the descriptor serial number of the firmware that I'm burning to the device but I don’t know how to change the descriptor serial number when the device is in Bootloader mode.

 

I add picture so you can see the problem inside the device manager.

 

You can reproduce the problem at your end by:

  1. Connecting 4 FX3 with J4 jumper insert under HUB
  2. Restart the pc
  3. Enter to device manger to see if the device enumerate proper

 

Thanks,

EliW.
