Mbed driver failure in Windows 11

Electronics and hardware
1

Hello.

Recently I tried plugging in my Mbed LPC1768 into my windows 11 laptop but the security policy was preventing my laptop from recognising the device I plugged in. Sometimes I was able to see the MBED directory in my file explorer and sometimes not.

I am also not able to find Ports (COM & LPT) section in the Device Manager. I can only see mbed Composite Device and it also has an error “Windows cannot load the device driver for this hardware. The hardware may be corrupted or missing (Code 39)” . This problem is not occurring on my Windows 7 system.

It was working fine just about a week ago but this problem has started to occur recently.

I have attached the screenshot of the Windows Security error

It’s my request to the Mbed team to kindly look into this issue.

Hello,

request to “Mbed team”, there is no team for years :slight_smile:
Try ask here mbed-ce/mbed-os · Discussions · GitHub it is not dead ARM Mbed but MbedCE and I am sure the maintainer has LPC1768, so he can propose some hints maybe.

However, did you try to update firmware anytime?
Moreover, Microsoft are ending support for some drivers time to time, so the reason can be caused by some Windows update from that time. You can find how to allow unsupported driver if possible via Google or AI .
