In 2009, ASMedia became the first company in Taiwan to obtain USB-IF Association certification for its USB 3.0 device controller chip, followed by certification for its host controller chip in 2011.

In 2014, VIA won a courtcase against ASMedia, after it sued ASMedia for using confidential VIA intellectual property related to USB technology, obtained from ex-VIA employees who had joined ASMedia.

In 2015, ASMedia became the first company in the world to obtain USB-IF Association certification for its USB 3.1 host controller chip and USB 3.1 to SATA bridge controller chip.

In 2016, the company launched the world's first second-generation integrated Type-C USB 3.1 (10G) to SATA bridge controller chip and obtained USB-IF Association certification.

In 2019, it unveiled the world's first USB 3.2 Gen2x2 controller chip and was selected as one of Forbes Asia's 200 Best Under A Billion companies.
