PIC32MX695F512L - USB Full Speed

Hi,
i am implementing pic32 as a host to read/write from usb flash drive. I am not using OTG (USBID pin is set as digital output) so i use only D+ and D- ports. Is it possible to use USB Host with full speed in that configuration? Now using SCSI and FatFs i am able to achive 165 Kbytes/s which is Low Speed (1,5 Mbit/s).
 
In the data sheet I've found only information about USB OTG full speed.
 
Thanks in advance for your answers! :)
