If you mean can you use the PIC as a 'master' to interface to a USB memory device ( the 'slave') then no.
The 4550 is a USB 'slave' device, the PC being the 'master'.
To have a PIC read/write to a USB 'stick' then you need a PIC that is OTG capable( On The Go), as it can be either master or slave.
To have a 'regular' PIC access USB memory sticks you could use any of the Vinculum modules. They allow any serial device to be 'master' and/or 'slave'.

It's been a few years since I did any 4550 coding,went the Vinculum route for datalogging.It was far easier,simpler,more reliable though cost a few pennies more.

others more 'up to date' may have more to say.......
