Blue Screening upon Connection

Previously, we have been using the cleverscope software, as well as the python interface, which all worked great. Recently, whenever we try to choose/connect to an acquirer, the computer immediately blue screens and shuts down. We get error codes like ftdibus.sys file failed, PAGE_FAULT_IN_NONPAGED_AREA, SYSTEM_SERVICE_EXCEPTION. I have opened the .dmp file produced from the crash and seen that it is caused by something in the cleverscope.exe but cant seem to hunt down the problem. I have fulling uninstalled the software and drivers, then reinstalled the multichannel install .zip file and rerun the setup file, but nothing changes. I am using a CS448 scope. are there additional drivers I need to reinstall upon re setup to make everything happy again, or perhaps something with my python dll was misconfigured or left connected during a recent power outage potentially causing issues (this outage was most likely the time when our issues began).

Is this a known issue? any advice or ideas?

Hi Erik,
That is not good and not something we have seen before. Can you tell me what version of windows and our application you are using? The ftdi driver is not used to connect to the CS448 so not clear why it is even involved.

Since it occurred after a power failure I would suggest first doing some disk management - first
DISM /Online /Cleanup-Image /RestoreHealth
followed by
sfc /scannow
and a restart

Even a chkdsk might be worth trying.

On my laptop I removed the ftdi drivers using an administrative terminal -
First find the driver package name -pnputil /enum-drivers
Look for ftdibus in the list — it will show an oemXX.inf name (e.g. oem151.inf). Then remove it using
pnputil /delete-driver oem151.inf /uninstall /force
The application connected to my CS448 fine without them.- - note that they are also used for Arduino boards etc as well.

There may be more than one of them.

Python should not be causing an issue but you will have had to re-install the drivers along with the application - however, not doing so would not cause a blue screen. When installing, do not click on the option to install the legacy driver for the CS328 - it is not required.

Let me know how you go. Once I have your software version I can do a bit more checking here on a test unit.

Regards,
Roger
