Ok this is just a guess but it should be seen as a USB mass Storage device by your system.
You should be able to define a mountpoint and mount it to it just as you would do with a regular hard drive.
#mkdir /mnt/usbflash
#mount -t vfat /dev/sda /mnt/usbflash
sda should be completed by a number indicating which partition you'd want to mount.
Edit : just stumbled into some sites that mention specific Linux drivers for their usb flash devices.
You might want to look at the manufacturer's website if there are any Linux specific drivers too.
