Technical Details: Technical Details:
* USB sticks / drives must be formatted with one of the filesystems listed under "FILESYSTEMS=" at ``/etc/usbmount/usbmount.conf`` — these are specified on/around Line 103 of: `/opt/iiab/iiab/roles/usb_lib/tasks/install.yml <https://github.com/iiab/iiab/blob/master/roles/usb_lib/tasks/install.yml#L103>`_ * USB sticks / drives must be formatted with one of the filesystems listed under "FILESYSTEMS=" at ``/etc/usbmount/usbmount.conf`` — these are specified on/around Line 17 of: `/opt/iiab/iiab/roles/usb_lib/files/usbmount/usbmount.conf <https://github.com/iiab/iiab/blob/master/roles/usb_lib/files/usbmount/usbmount.conf#L17>`_
* If your IIAB was built on a Graphical Desktop OS (instead of a headless OS, like Raspberry Pi OS Lite), USB sticks will problematically be mounted twice by default, once by usbmount and once by the desktop. You must disable the automount function in the Desktop in order to use the "Upload to USB" functionality, which allows students to upload their work to your USB stick.
* EXAMPLE: To disable Desktop automount within "Raspberry Pi OS with desktop", go to File Manager (pcmanfm) → Edit → Preferences → Volume Management, and uncheck "Mount removable media automatically when they are inserted".
* IIAB will generally mount USB sticks / drives 'rw' allowing root to both read and write to them. In addition, in March 2021 (`PR #2715 <https://github.com/iiab/iiab/pull/2715>`_) Kolibri exports were enabled, by also giving non-root users read and write access to VFAT/FAT32, NTFS and exFAT USB sticks — using ``umask=0000`` (in /etc/usbmount/usbmount.conf) to override the ``umask=0022`` default. This ``umask=0000`` is also required for students to upload to the teachers's VFAT/FAT32, NTFS and exFAT USB sticks, as introduced in January 2025 (`PR #3875 <https://github.com/iiab/iiab/pull/3875>`_). If, however, you prefer to restore usbmount's default, set ``usb_lib_writable_sticks: False`` in `/etc/iiab/local_vars.yml <http://FAQ.IIAB.IO/#What_is_local_vars.yml_and_how_do_I_customize_it%3F>`_ — please do this prior to installing IIAB — so you don't have to run: ``cd /opt/iiab/iiab ; ./runrole --reinstall usb_lib`` * IIAB will generally mount USB sticks / drives 'rw' allowing root to both read and write to them.
