Important notes regarding operation of the CRYPTO-BOX on USB 3.0

Status Update about the CRYPTO-BOX Versa / XS USB 3.0 issue and workaround.

It has come to our attention that some customers are encountering difficulties when operating the CRYPTO-BOX XS and Versa to USB 3.0 ports.
In our tests we were able to reconstruct the systems that are equipped with chipsets of Intel 7 series. The CRYPTO-BOX is recognized but it will show error messages when querying the CRYPTO-BOX.

The affected CRYPTO-BOX models are XS and Versa, the CRYPTO-BOX SC works flawlessly on USB 3.0 ports.
Our analysis has shown that the USB 3.0 controller on the affected systems does not accurately respond to specific requests of the CRYPTO-BOX driver. We are in contact with the chipset and motherboard manufacturers and are working to resolve this issue. We will keep you up-to-date on this subject via our website and in our weekly newsletter.

For the affected systems there are possibilities of working around:

• 1. Connect and operate the CRYPTO-BOX to a USB 2.0 port. Most motherboards have both types of connectors. You can recognize the USB 3.0 connections because the sockets are blue, USB 2.0 ports are usually black or white.
• 2. Turn off the xHCI mode in your computers BIOS settings. By this, the super-speed of the USB 3.0 ​​interface will throttle down to high-speed (USB 2.0), in our tests it ran perfectly. Most motherboards allow to disable the xHCI mode in the BIOS selectively to individual USB 3.0 ports, so you can still use the other ports at full speed.

Your feedback on using motherboards and USB controllers is appreciated as it helps us to improve our support for you.

Please provide us with the following information, in this regard:

• 1. MARX Analyzer Report: download the MARX Analyzer on www.marx.com/downloads and perform the standard diagnostic. Save the report (.mdiag file) and send it to us via email.
• 2. Information about the computer you are using, especially:
  - Motherboard manufacturer, model, serial number, hardware revision, and BIOS version
  - Version number of the USB 3.0 driver, you will find it in the device manager under: USB controller -> USB 3.0 Host Controller -> right click -> Properties -> Driver
• 3. What are the symptoms:
  - Is the CRYPTO-BOX partially recognized, or not at all?
