Save data to Usb with Arduino Uno and a USB host shield

Hello,
I am trying to save data using my arduino Uno to USB using an USB shield host. I however have no idea how to acomplish this or if it is even possible. Can anyone help?

For example I want to save this data to a .txt on usb using this shield host:
"Voltage,Resistance,Temp
3.45,1000,23.56
3.57,1021,23.87
3.79,1043,24.00"

I am currently just printing this data to serial monitor.

Thanks!

EDIT:
I am trying to use this USB shield:
USB host controller, MAX3421E by sparkfun

What do you mean by "USB shield host"?

I am propably using the wrong name for it, I'm just starting to use the Arduino. I put a link to the one I have in the post, the description it gives on the website is "USB host controller, MAX3421E" made by sparkfun

Thanks for the reply!

OK, so in the phrase

What do you mean by "to USB"

The existing USB mass storage libraries for MAX3421E host controllers with file system support are too large for Uno. You will not be able to write files to a USB storage device with your Uno.

I meant to save it, so it's accesible on a laptop.

Thanks for the help, A shame it can't be done!
