Frequently Asked Questions

• Are these blockers compatible with USB Type-C ports?
  No, they are specifically molded for standard female USB Type-A ports only.
• Will this fit into USB 3.0 and USB 2.0 ports?
  Yes, the physical dimensions of the outer shell are identical for both USB 2.0 and USB 3.0 Type-A ports.
• Does this work on Mac laptops as well as Windows PCs?
  Yes, this is a purely physical block and is completely independent of the operating system or device brand.
• Can I use this on server racks and network switches?
  Absolutely, they are ideal for securing exposed USB Type-A ports on enterprise networking gear and servers.
• Will inserting the blocker short out my USB port's power pins?
  No, the blockers are made of non-conductive polycarbonate that safely rests against the internal pins without causing a short circuit.
• Does the blocker draw any current from the host device?
  It draws absolutely zero current because it contains no internal electronic components or conductive traces.
• Can the blocker melt if the server gets too hot?
  The hardened polycarbonate material is rated to withstand standard operating temperatures up to +85°C without deforming.
• Does it matter which way I insert the blocker?
  Yes, it must be inserted in the standard orientation just like a regular USB drive to match the internal plastic tongue of the port.
• Will removing the blocker bend the internal USB data pins?
  As long as you use the provided metal extraction key and pull straight out, the internal pins remain perfectly safe.
• Can I force it into an RJ45 Ethernet port?
  No, the dimensions are strictly for USB Type-A; forcing it into other ports will cause permanent physical damage. 
• What should I do if the metal extraction key gets lost?
  You will need a replacement proprietary key of the exact same design, as standard tools like paperclips will likely damage the port if used for extraction.
• Why won't the blocker go all the way into the port?
  Check inside the USB port for existing dust or debris, and ensure you are inserting the blocker right-side up.
• Will my operating system show a "device connected" notification?
  No, because the blocker has no internal circuitry or data lines to trigger a USB handshake with the host OS.
• Is this better than disabling USB ports in the BIOS?
  It is highly recommended to use physical blockers in conjunction with BIOS restrictions to provide a robust two-tier endpoint security defense.
