I have a feeling that this will either be really easy or really really hard and i doubt its easy :P. Anyway, what i want to do is connect a USB flash drive to a PIC chip and load data from it. All the files that will be accessed will be in a single folder. I want to have a numberic display and up/down buttons to select a file then read so many bytes of the file at a time and send them to another chip using serial. I see PIC chips have built in USB support but is that just for connecting to a PC?

Ive been looking on google and i found one of these.

I think thats exactly what im looking for. Can anyone see any reason why that wouldnt suit me or should i go and order some?

Theres no datasheet for that as far as i can see but i think this is the same chip.

1 other thing i forgot to ask. Would i need something like this to connect a chip to a PC or is the built in USB support good enough for that?
