Can I use a usb hub to transfer images from my phone into another device?
Solution 1:
No hub is required, as long as both the PC and the phone are connected to your local network and can see each other.
The simplest method is to install an SSH server on your phone, for example SSHDroid on Android. Once launched, you could access the phone's files from Windows.
A great (free) Windows utility is WinSCP.
Some small knowledge (or experimenting) will be required via WinSCP to find the phone folder containing the files to transfer.
