IsLineChanged and USB_GetDTERate never changes when setting baud rate on PC
I am building a USB->serial bridge mode as part of a project. To enter bootload mode on the downstream device, the UART baud needs to change on the fly. I was hoping to detect the baud change on the USB interface using the USBFS USB_GetDTERate command (after detecting change with IsLineChanged). I am not seeing any changes when I change the baud of the serial terminal on the PC. Is this a driver issue on the PC? Do I need a different driver or configuration of the USBFS component to pass through the baud rate changes?

Hi,
Please find the solution to the issue at the same community thread created here : https://community.cypress.com/t5/PSoC-5-3-1-MCU/Change-in-Baud-on-PC-does-not-cause-USBFS-USB-GetDTE...

Hi @AnSa_1225656 ,
Can you please help me with few details related to your project here ?
1. Since you mentioned you are building USB-serial bridge mode, I am assuming you are using USB-UART bridge to proceed with your application. Hence, can you please let us know if you are using a UART component for this or have you used a USBFS component configured as CDC device here?
2. Do you have another USBFS component besides UART to detect the baud-rate change and how exactly have you configured the descriptor of USB then?
Please let us know your comments regarding this.
Best Regards,
Aashita
