Hi everyone is there any chance to execute a parallel firmware update on Windows using fdt2.exe on multiple modules at once? I see it is doable under Linux using swiflash where one can specify multiple USB ports, but do not see this option for FDT under Windows. Any help is much appreciated. Thank you ---

From the application note below, I don’t see it can specify the com port number: [https://source.sierrawireless.com/resources/airprime/software/fdt/#sthash.sJcDASwB.dpbs](https://source.sierrawireless.com/resources/airprime/software/fdt/#sthash.sJcDASwB.dpbs) ---

Hi @Wiviacom You can use “fdt2.exe -h” for a full list of available FDT options and version information. Please try it with `"fdt2.exe -f -usbport # -usbhub # -multi"` -usbhub [hubnumber] Restrict devices to this USB hub number. -usbport [portnumber] Restrict devices to this USB port number. Please help to tick “Solution” if your question is answered. ---

Hi Donald Thanks for your suggestion. Where can I get fdt2.exe please? I can only find fdt on Sierras website. Please advise. Thank you ---

> [@Donald](#): > > fdt2.exe -f -usbport # -usbhub # -multi One more questions please: I am trying to figure out, what should be used as USB port number in this case? I am trying to use either the Loc ID from usbview.exe software or COM port number. None of them is working. Any thoughts please? THanks ---

Hi Wiviacom, USB port number is modem port in Sierra Wireless WWAN Modem. For example: usbport is 246 fdt2.exe -f WP76xx\_Release16\_GENERIC.spk -usbport 246 -multi ![usbport](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/1/15249c5dc2820ff081e0440143e6bbb41a959e4b.png) ---
