Control USB Devices in Office Block Storage Allow Trusted Drives

A USB control tool only enforces decisions - it cannot make them for you. Before you install anything, write down three simple answers on one page:

1. Which devices are banned? For most offices: unknown pen drives, personal external hard disks and phone storage.
2. Which devices are allowed? The specific drives the office itself buys and issues - these become your trusted device list.
3. Who approves an exception? One named person, with one clear way to ask. Without this door, staff will find their own doors.

Send this one page to the whole team before enforcement day. A rule people hear about in advance is a policy. The same rule discovered by surprise feels like spying, and it breaks trust you will need later.

Device Control Plus works like most ManageEngine products: one central server on a PC or server that stays on, and a small agent on every office computer. The agent is what actually blocks the device and reports back - the console only sends it instructions.

1. Install the Device Control Plus server on the admin machine and open the console in the browser.
2. Add your computers - in an Active Directory office they can be picked from the domain; in a small office, push the agent from the console or install it manually.
3. Confirm every PC shows as connected in the console before you write a single policy. A policy pushed to a PC whose agent is offline does nothing until the agent checks in - although once a policy is applied, enforcement continues even while that PC is offline.

The exact console steps are shown live in the video above - follow them there, and use this page as the plan around those clicks.

The most common beginner mistake is blocking the USB port completely. Do that and keyboards, mice, printers and barcode scanners die along with the pen drives - and your Monday morning becomes a queue of complaints.

1. In the policy, target the removable storage device class - pen drives, external hard disks, memory cards and phone storage.
2. Leave human-interface devices (keyboard, mouse) and printers outside the restriction.
3. Choose the action per group: block for unknown storage, read only where staff may view files but must not copy them out, and full access only where the job truly needs it.

Device Control Plus also lets you cap transfers by file type and file size, which is useful for a middle path - for example, documents may move but large archive and video files may not.

Blocking everything is easy. Keeping work moving is the real job, and that is what the Trusted Devices list is for. Every drive the office officially owns gets added once, by its device identity, and then works normally on every managed PC - while a visually identical drive bought from a shop stays blocked.

1. Collect the office drives, plug each into a managed PC once, and add it to the trusted list from the console.
2. Label each drive physically - a sticker with the same name you used in the console saves endless confusion.
3. Keep the list short. A trusted list with 60 drives on it is not a security control any more, it is just a slower version of allowing everything.
