reading data from microcontroller to c-code using libusb-win

Question

Hello everyone, We are working on a final year project and we are stuck in the part where reading data from microcontroller through UART_TO_USB_CONVERTER to a c-code where we are recognizing the usb by libusb-win32 APIs. Problems to be solved:
1. usb_bulk_read is not working so really need a solution for this.
2. Can someone please help with the code to print the data read from the usb.(a code burnt in microcontroller which prints a letter "A")
3. Does the baud rate of 8051 matter while reading data through libusb-win32.
