There was a time several years ago (prior to GoldenOrb being compatible with the Sierra Wireless line of modems), a group of us were building Windows PC's to act as a combination PC, LTE router and media center (running Kodi). We used various Virtual Router Managers to share the WiFi from the PC.
We faced the same issue with the host PC not detecting the MC7455 installed internally in a Mini PCI-E adapter. We too had to tape the PINS for the MC7455 to work.
It seemed the corner of a yellow stick-em and an exacto knife (and magnifying glass for those of us with tired eyes) simplified the task of isolating the interface pins.
Here is one such PC build:

Taping the PINS on the later hardware versions of the MC7455 is no longer required. This can be accomplished using an AT Command.
To use this function, the MC7455 must be first be updated to the latest
Generic firmware.
To update the firmware will require a
USB to Mini PCI-E adapter to connect the modem to a PC.
In order for a Windows machine to detect and communicate with the MC7455, the Sierra Wireless
Generic Driver Software for Windows will need to installed on the PC.
Warning: Never allow a Windows machine to "Manage" an internet connection with the MC7455 as it can change the composition of the modem to an undesired mode. In other words, if you are using an USB to Mini PCI-E adapter enclosure, remove the SIM Card where Windows will not try to manage the modem. Windows is used strictly to update the Sierra modem's firmware using the Generic Driver Software.
Plug the USB adapter (with the MC7455) into the Windows machine and run the GN_9999999_9904609_SWI9X30C_02.30.03.00_00_GENERIC_002.046_001 executable file.
When the update is completed, you should see this window with these results:

If your window reflects these "exact" results, press the Enter key and the window will disappear.
If your results look any different, press Enter key, and update the firmware a second time.
Note: As a general practice, I personally prefer to
always flash a firmware on a modem a second time. It is also often required on the EM7565.
After the firmware has been updated, we will use the
Huawei Terminal to issue the necessary AT Commands.
Open the Huawei Terminal and select the WWAN Modem COM Port, and Connect:

Once connected, run the following AT Commands:
Code: Select all
AT!ENTERCND="A710"
AT!USBSPEED=0
AT!RESET
Once the last AT Command responds with OK, Close ( X ) out the Terminal.

You may now remove the MC7455 and install in the M2M and proceed as normal with configuring GoldenOrb.
In the event you need to restore the MC7455 to it previous USB OEM setting:
Code: Select all
AT!ENTERCND="A710"
AT!USBSPEED=1
AT!RESET
As an afterthought, we expect changes in the
M2M NEXG H721 Version 2 that will void having to complete this step.
When you purchase the
M2M NEXG H721 Version 1 from The Wireless Haven along with the Sierra Wireless MC7455 modem, we will update the firmware and configure the modem for no additional fee. Just
include a note upon checkout in the NOTE field box to
"Prepare the Modem for the M2".
