I'm hacking a design who is already made with a PIC32MX in order to attach a FTDI CHIP to the actual design. This FTDI it should serve a purpose to make a "bridge" between USB and UART in the way to put this Fingerprint Reader working properly. I am not using any UART communication because I don't have any more UART Ports available. That's the only reason why I am trying to put the USB module working.
The VUSB pin is connected to the VCC_3V3 but in the datasheet it's mentioned two opposite information. In the page 41 they say "USB internal transceiver supply. If the USB module is not used, this pin must be connected to VDD." and in the page 45 it's mentioned "Note 1: If the USB module is used, this pin must be connected to VDD." What should I do?
The power to the FTDI is given by the 5V regulator and I am not using (ignoring) the VBUSON pin 11 neither the VBUS pin 34 and I have the FTDI connected to the USB pins 36 and 37 for D+ and D-.
Regarding that I am using the pin 11 to reset the Bluetooth module which I have in the design, do you feel that I really need that pin to put the USB working properly?
What should I do with the pin 34 (VBUS)?
To put the whole system working correctly I must configure the USB as CDC Host, right?
