PIC32 USB CDC No function after last update

[SpeedPIC32]

Hello all,

something went wrong with the last USB update.
In FC9 and FC10 the USB interface is no longer recognised by my computer. Please make the old version available as soon as possible.
there is no error message when compiling.

Do you mean the last update to the USB component? If so, you can revert to an older component using the "Help...Library Updates" screen using the following steps:

1. Open your project in Flowcode
2. Open "Help...Library Updates"
3. Tick "Show up-to-date files"
4. Tick the file you want to change
5. Click on that row in the "New Revision" column and select the older version you require
6. Click "Download" to revert that file to the earlier version
7. Restart Flowcode and try your project again

If your project compiles with the reverted component, then please post the following files as this will help us determine what the problem is:

• Your *.fcfx project file
• The generated C code file for the working project
• The generated C code file for the project that is not working

Also please tell us which version of the component worked for you.

hello steve.
the compilation works perfectly. nevertheless, the interface cannot be found.
fc9 and fc10 compile without errors and the rs232 port is no longer there.

I believe this to be a Windows security issue as the generated driver is not signed.
Therefore, from Windows 10 onwards, unsigned drivers won't be loaded.
There are workarounds for this.
For example, loading Windows in safe mode:

Hello medelec35

I don't think so. I have a hex file that runs.
I was able to compile up to the update and had no problem with it. the special thing is that the update is for FC10 and FC9 is also affected by it.

hello,

where can I get a driver that works?
I have tried the error under win 10 code 43
without success.
I need this driver urgently.
Who can help?
Is it possible to use the driver from Harmony 3?

HI,
have you looked at this wiki page?

Sorry, but I am not sure exactly what you mean. What specific update are you referring to?

Error hello Steve-Matrix,

there was an update Pic32 USB files about a week ago.
Before the update I could program my Flip Clickboard with a PIC32MZ2048EFH100 with USB CDC. it was enough to select under comms: USB CDC and call the initialisation and the PC with win10 showed the USB Serial interface. now this always comes up in FC 9 and 10.
I installed the update with FC 10. The possibility to play it back does not work.
FC9 and 10 access the same batch file. is it possible that an error has occurred? where can I load the file for exchange? is there a possibility to work with Harmony 3?
