This article describes how you can simulate a USB disk through a simple shared folder in URSim.
Step 1: Create a shared folder in VirtualBox.
Go to Devices / Shared folders / Press the + button.
Shared folder settings in VirtualBox
Select the folder you want to share. This folder will be visible as a USB disk in the simulator.
NOTE: Don’t use a real USB disk. Just use a simple folder.
Creating a shared folder called ‘simUSB’ in VirtualBox
Step 2: Make the folder accessible by the simulator.
Open a terminal in the simulator. Enter the following commands.
NOTE: commands are case sensitive! Type exactly what is written here, including spaces and any special characters.
sudo mkdir MYUSBDISK
sudo chmod 777 MYUSBDISK
sudo mount -t vboxsf -o rw,uid=1000,gid=1000 simUSB MYUSBDISK
Step 3: Make the new shared folder visible by Polyscope as a USB disk
Using the same terminal, enter the following commands, exactly as written here:
ln -s /media/ur/MYUSBDISK usbdisk0
The new folder is now ready to use.
