Is it possible to use a PIC18F14K50 USB in low speed mode?

I'm developing a portable device and need to use a 6MHz Crystal so I need to use low speed mode.

Yes.
However remember that not all devices support low speed.
So you cannot support bulk transfers on a low speed device, which
rules out an MSD device for example.
HID device, no problem.
