Hello Bjorn,
Thanks for your help, the problem is solved and the blame go to the
usb_modeswitch executable that failed to change the configuration.
However, changing the configuration was successful when writing directly into
the kernel :-)
My Linux system already use the latest usb_modeswitch (2.5.1) and libusb (1.0),
so it seem that the blacklist of the HID driver is a local work-around for a
problem with my Linux system - and is not relevant to others.
Thanks

Notes:
* Tested with Linux kernel 3.14.15 on a 32bit ARM machine (kernel is compiled
without IPV6) and with static HID driver
* Novatel Linux integration guide -
https://www.verizonwireless.com/dam/support/pdf/verizon-usb730l-integration-guide.pdf
The following was used to switch the Novatel USB730L from user mode
(product ID 0x9030) to enterprise mode (product ID 0x9032):
* Kernel patche: add Novatel USB730L enterprise mode serial interface
