for all power users and geeks that would like to use their microphone with Oculus Rift headset find below a description how to install it.

If you want to use your microphone for your Oculus Rift headsets there is a way to enable your TPCAST wireless adapter to support microphone function. This patch needs to work with a specific Connection Assistant software designed for microphone support.

To enable microphone function, you need to open your TPCAST power box to remove and flash the SD Card with a new Mic supporting firmware. We recommend saving a backup of the old image file from the current SD Card to be able to restore the device to factory settings or use a new SD Card instead. For best performance format the current or new SD Card with SD_CARD Formatter tool.

Following tools are needed: PC, Screwdriver, Card reader (optional SD Card)

Please download following software to enable your TPCAST wireless adapter to support microphone function.
