Microsoft Windows drivers
Dell EMC provides an ME4 Series USB driver for use in Windows environments.
Obtaining the USB driver
NOTE: If you are using Windows 10 or Windows Server 2016, the operating system provides a native USB serial driver that
supports the mini-USB port. However, if you are using an older version of Windows, you should download and install the
USB driver.
1. Go to Dell.com/support and search for ME4 Series USB driver.
2. Download the ME4 Series Storage Array USB Utility file from the Dell EMC support site.
3. Follow the instructions on the download page to install the ME4 Series USB driver.
Known issues with the CLI port and mini-USB cable on Microsoft Windows
When using the CLI port and cable for setting network port IP addresses, be aware of the following known issue on Windows:
Problem
The computer might encounter issues that prevent the terminal emulator software from reconnecting after the controller
module restarts or the USB cable is unplugged and reconnected.
Workaround
To restore a connection that stopped responding when the controller module was restarted:
1. If the connection to the mini-USB port stops responding , disconnect and quit the terminal emulator program.
a. Using Device Manager, locate the COMn port that is assigned to the mini-USB port.
b. Right-click on the Disk Array USB Port (COM
n
) port, and select Disable device.
2. Right-click on the Disk Array USB Port (COM
n
) port, and select Enable device.
3. Start the terminal emulator software and connect to the COM port.
NOTE:
On Windows 10 or Windows Server 2016, the XON/XOFF setting in the terminal emulator software must be disabled
to use the COM port.
Linux drivers
Linux operating systems do not require the installation of an ME4 Series USB driver. However, certain parameters must be
provided during driver loading to enable recognition of the mini-USB port on an ME4 Series controller module.
● Type the following command to load the Linux device driver with the parameters that are required to recognize the mini-USB
port:
# modprobe usbserial vendor=0x210c product=0xa4a7 use_acm=1
NOTE: Optionally, this information can be incorporated into the /etc/modules.conf file.
