i have an arduino uno R3 and i want to record data from temeperature sensor directly to USB drive. is there any option that i would be able to record that data without any sheelds like VDIP 1 and others? and how?
Uno is a USB slave. USB drive is a USB slave. Need a USB Master (Host) in the mix.
You need a USB Host shield to do that. Uses MAX3241E for host interface, Uno talks to MAX3241E via SPI.

No. As explained, you need a host shield but you can get a shield that is more approrpriate to Uno and at a less insane price than I have seen the VDIP 1 offered at. I got a Funduino host shield. It is good for Uno and Mega.
It usually makes more sense to use a SD card rather than a USB device.
