Hello,

I am testing the reception of files from the Windows Form Application by referring to "usb_device_cdc_vcom".
(1) In order to confirm the transmission contents of the host, the transmission data of the host was acquired with a USB analyzer and compared with the original file.
→ The host was sending normal data.
(2) In order to check the received contents of the device, the USB reception buffer of the device was acquired by the IDE and compared with the original file.
→ I found that some of the data was not received correctly.
So I decided that the LPC5514 wasn't receiving the data. What could be the problem with this?Diff.png

Thank you for helping.
The problem was in the hardware.
As a result of verification on another board, the phenomenon did not occur.
