Windows 10 Working Fix for Crashing Asyra/Qest Systems During
Screening. (Blue Screen of Death)
This is only relevant to those who connect their Asyra or Qest to the computer using the USB
cable. Those who connect via Bluetooth will not have the problem unless they connect with the
USB cable.
The problem will only occur if you have FTDI driver version 2.12.24.0 installed.
This solution is suitable for Windows 7, 8 and 10 and has been tested extensively on both Windows 7
and 10, but please note due to the way Windows behaves this process may need to be revised over
time. We will be monitoring this and will produce updates as required.
Some background information.
Your Asyra or Qest uses a "driver" to communicate with your computer. This driver is only activated
in Windows when you connect your Asyra or Qest to the computer.
Windows will automatically update this driver when the device is connected to the computer and
your computer is connected to the internet. It is currently not possible prevent this in Windows 10
Home Edition and although it is possible in Windows 7 & 8 and Windows 10 Pro or higher it not easy
and involves changing settings within the Windows software and is not advisable for the average
computer user.

5.
Preventing future automatic updates of the faulty driver
There are several ways to achieve this.
Option 1 - Simple, works for all version of Windows but has limitations such as not being able
to use the internet whilst your device is connected to the computer.
Never connect your device whilst the Wi-Fi is switched on or Ethernet cable is attached.
This is the only option available to people using Ethernet connections (all Windows
versions) and Windows 7 users.
Reminder for future reference
Step 1 Ensure the Asyra/Qest is not connected to the computer.
Step 2 Turn on your computer.
Step 3 Disconnect from the internet - unplug the Ethernet cable or turn off Wi-Fi.
Step 4 Now connect your Asyra/Qest to the computer and do your testing.
Step 5 If you need to send emails or access the internet, close the Asyra/Qest program, turn
off and unplug the Asyra/Qest before connecting to the internet.
Updating the Asyra/Qest software can be carried out without having the machine
connected. Just run the program in the normal way, Wi-Fi on or Ethernet connected but
device not connected to the computer.
Option 2 - Thorough but only available for Wi-Fi connections on Windows 10. At time of
publishing this document we cannot confirm if Metering prevents drivers from auto installing
in Windows 8 but it is available. This option only focuses on Windows 10.
You will need to know which version of Windows 10 you have installed.

To find the version number open Settings
ii.
Click System
iii.
Scroll down and click About
Version number is shown, as is other useful information.
What does setting a connection to METERED do?
Setting a connection as metered prevents Windows from automatically using bandwidth in
many ways:-
•
Disables automatic downloading of Windows updates
•
Disables automatic downloading of app updates
•
Disables peer-to-peer uploading of updates
•
Disables the downloading of driver updates
•
Tiles may not update
•
Other apps may behave differently
When you should set a connection as Metered
Microsoft says you should set a connection as metered if your Internet service provider
limits the data you can use. However, you may also want to do this to prevent Windows
from using your bandwidth except when you choose, especially on slower connections.
Note:- Windows only allows you to set Wi-Fi and mobile data connections as metered by
default — not wired Ethernet connections.
Turn on Metered Connection Windows 10 version 1511
i.
Open Settings
ii.
Click Network & Internet
iii.
Click Wi-Fi
iv.
Select Advanced options at the bottom of the list of nearby Wi-Fi networks
Turn on the “Set as metered connection” option here.
IMPORTANT
Note that this just affects the current Wi-Fi network you’re connected to. Windows will
remember this setting, however, and that particular Wi-Fi network will always be treated as
a metered network whenever you connect.
As soon as you leave the Wi-Fi network and connect to another Wi-Fi network that isn’t
considered metered, Windows 10 will resume automatically downloading updates and using
the other restricted features. You’ll need to set that Wi-Fi connection as metered after you
connect to stop this from happening. Do this before connecting you Asyra/Qest to the
computer, otherwise the faulty driver will automatically download and the BSoD problem
will occur.
Note:- It is still possible to manually update any other drivers if required, you will need to
locate the relevant driver in Device Manager and in the properties select Update Driver
under the Drivers tab.
