* Total cable length includes case internal cabling plus external cabling. Sub-par cable thickness/quality and external port design/quality may also reduce supported length required for maximum performance.
** If your OS version is Windows 7 or earlier, please install driver (available from SilverStone website) prior to using the ECU04-E.
*** Windows 8, 8.1, or 10 supports ECU04-E automatically so you do not need to install additional driver for it.
**** User should check for XHCI function in Ubuntu/Linux or Mac OS, if computer system supports XHCI function then it can support ECU04-E automatically without additional driver installation.
***** If your operating system is incompatible with the expansion cards developed by SilverStone, such that your device can not be detected or recognized, please update your motherboard’s driver or BIOS to the latest version.
