> I use 6 MC7430 modems on a unit, the USBCOMP configuration is 50D.  my test is do firmware upgrade for all modems one by one after system bootup. the test environment as below:
> SDK version: SLQS04.00.17
> GobiNet driver: S2.34N2.53
> upgrade command like: ./fwdldhostx86_64 --sdkpath ./slqssdk --device 9x30 --path /tmp/test/MC7430/0224 --modem $index

The Sierra Wireless forum is a better place to ask this kind of questions related to the Sierra GobiNet and their firmware upgrade tool:
