Hi,
Recently I used example code ot check how USBUART CDC works, but I can't connect to COM Port. I've got an error. Changing USB port and restart computer also not fix that issue. It's seems to be Microsoft Error. As I was able to establish usbser.sys block this COM port, but I don't know how to unblock this port. Any suggestion?
Thanks for helping.
Hello @Tranzystomator
Can you please let me know if you have connected the USB port of the PSoC ( and not the kitprog USB port) to the PC?
Make sure you have chosen the correct USB pins in the project.
Can you check if you are connecting to the correct COM port?
After programming the PSoC device with the USBUART code example, if you go to device manager, under the PORTS section you should see the USB device as USB serial device, COM 21 in my case.
Can you try using some other terminal emulator, like tera term? I tried using the tera term and it worked for me.
Since Windows 10 has predefined drivers for the USB CDC class, I have also used the usbser.sys in my case.
Kindly let me know the exact error you are getting if the issue persists in your case.
Thanks and Regards
