and I dont think thjat you will find an answer. You will have to write your own usb driver for interfacing.

You need to have a usb driver/controller chip in your system such as the FTDI device, part number FT245BM or one of its variants. These are readily available, cheap and easy to interface to one of the AT89C51 8 bit parallel ports with a few of the other I/O line for chip control. The device comes complete with ready to use drivers, which work

My Platform Cable usb II works just fine on my Win2k computer. I also have a Platform Cable usb and WinXP system. I can mix them around with no problems. I'm running ISE and EDK 10.1.03 tools. I haven't used ChipScope, in case that's where your problem occurs.
I haven't used FCPU-X.

Don't get confused, you can only connect a host to a device.
If you have two devices they cannot be connnected together.
The phone is a device and the PIC18F4550 is a device as well.
You need to get a microcontroller with a usb host and this can be connected to the phone.

Yes, you should be able to use usb and SPI together as they do not share pins.
You could also run SPI and rs232 if you used a Software Usart with some other free i/o pins, don't know if your C library will have one though ? - might find one ready made on the web.

I won't say it's impossible, but it's highly complicated. The reason is that you need a usb host to read data from a usb device. On the other hand, if you can get your hands on an OTG controller, things may be slightly easier.
