To answer your question. No. You are missing a host controller. The Pic only has hardware support for a device, not a host. The good news is there are Host controller IC's available. Some use USART some use SPI some use I2C. To answer the second part of your question, again.. no. You did not waste any time. If you learned something from the process, your time was not wasted. We failed several times before we were actually sucessful.
The 16 bit PIC will do the job. We use a 32 bit ARM and an 8 bit pic. But the 24 series should have enough power to support HID. Our next revision we will probanly eliminate the ARM chip. Actually an 18 series(8 bit) is all you need for HID. Remember this is hardware, it is not loaded up with a bulky operating system like Windows or Linux.
