USB no response when debugging in MCUXpresso IDE v11.3.1

[Peter1966]

There is a gdb warning appear as attachment, always.

 Even it can setup breakpoint, but USB never response.

Does MCUXpresso conflict with Symantec antivirus program ?

I use custom board RT1052 MCU debugging on MCUXpresso 11.3.1.
My system use a USB device to communication with PC.

After power on PC will sent a "GET descriptor" to address 0 in first step.
My system work well for a long time.

In my feeling, some days, Symantec announce a "Endpoint protection ..." warning !
Then my system become no response to "GET descriptor" to address 0.
But IDE can set break point. And it looks like system had ACK then stop.

I try to downgrade my code to previous version.
Every version got same problem, even it is initial version.

Hello Peter, 

Yes, we have seen in the past that some antivirus block the USB communication between the PC and the RT. Are you able to test this on a computer that doesn't have an antivirus? Also, you might want to contact the support of the antivirus to see if there's a way to add the RT to some sort of whitelist.

Hello Peter, 

Could you please provide more information about the behavior that you are facing? For example, when does this error appear? As soon as you launch a debug session? If so, are you using a custom board or one of our EVKs? What debugger are you using? 

Regards,
Victor

Custom board : MCU RT1050

IDE : MCUXpresso IDE v11.3.1

LinkServer Debugger : SWD; axf file

System work as a USB device.

After power on PC will sent a "GET descriptor" to address 0 in first step.
System no response to "GET descriptor" to address 0.
IDE can set break point. It looks like system had ACK then stop. Software isn't got the "GET descriptor" command.

PC send IN got NAK for a long time. Then time out.

In my feeling, some days, Symantec announce a "Endpoint protection ..." warning !  Then ....

I had update the code for 15 revision. Every version was debug in MCUXpresso IDE environment then release. 

I try to downgrade my code to previous version. Every version got same problem, even it is initial version. I don't think so the problem come from my code.
