Hello Members,
can someone help me out please!

Enviroment is OSX 10.9.1 with Virtual Box and 16GB USB.
I always run the VB any generate a VM on my hard drive as virtual hard disk with Linux Debian setting.
The iso is on my hard drive too.
The pen drive is formatted with FAT32 and 1 partition. Bootable.
In the VirtualBox setting i enable the pen drive. As storage i set always the pen drive.

BUT...everytime when it comes down to step 4 in the installation of Kali (guided installation and i need to confirm in this step where to run the installation) doesn't show up my pen drive at all. In the terminal window (GUI) bottom right side is always written that the USB is not active. If i click on it then shows up the pen drive but i can't select it.

12 hours i tried now...min. 20 attempt. Always the same failure. I tried it with VMware too...same issue.
