Installing USB CDC-ACM Virtual COM Port

Note: To install the USB driver for the MTCBA-H5-U model, download the guide USB Driver Installation Guide,
part number S000553. Follow the instructions in that guide to install the USB driver.
Windows XP (SP3 or greater), VISTA, 2003 Server, Windows 7 (32-bit or 64-bit), Linux (Kernel 2.6.xx using CDC-
ACM module) are supported.
For Linux, a 2.6.28 kernel or greater is required. The standard CDC-ACM driver works.
Note: Some versions of Windows have an issue with their CDC-ACM driver (Usbser.sys). If you are having
connection problems (file download, web pages not loading) your version of Usbser.sys must be updated.
Microsoft article 925681 documents this issue and provides a fix.
After installing the virtual com port, the correct modem driver may be installed to the com port (for the USB
