PIC32 USB CDC Error

[SpeedPIC32]

Hello Stefan

I use my own board.
runs on 20 MHz, LCD 2x16, ADM485.
this is a display for a high-precision 1bar pressure sensor from Keller.
had only quickly tested whether I can compile without a functional test on the board. I have successfully made up for this with small changes in the Pic config.

greetings SpeedPIC32

Hello everyone,

Why is no one addressing my issue?
Who is willing to assist me in resolving this issue?
What should I test and how?
Thank you for your numerous suggestions.
Unfortunately, it is still not working.

Best regards, SpeedPIC32

Another test.
The error occurs as soon as I call up
USB_Serial1.

hello.
Sorry for the delay.
We are looking at this issue, but is taking longer than planned.
We will update you when we have a solution.
Can you bump this topic rather than adding duplicated topics.

[SpeedPIC32]

Can you move this topic to the top instead of adding duplicate topics?

Sorry, I don't know how to do that.
I didn't know you could move a topic.
A little note saying that you were working on it would have been reassuring. I would have had time to test the changes. Would that be helpful?

Kind regards
