Does it support flash drives (via OTG)?

[GoogleCodeExporter]

I would like to trasfer photos from my camera to a flash drive by connecting 
them to my smartphone, using a hub and an OTG cable.
The app works perfectly and allows me to trasfer files to the smartphone, but 
doesn't see any flash drive connected. For this reason I have to first copy 
files to the smartphone and then to copy them to the flash drive.

Would you please tell me if is there any solution that could work?
If only the app could see the flash drive I would save a lot of time.

Thank you very much
