USB Universal Serial Bus - Draytek Compatible Computer Devices

Description extracted from Wikipedia:

DrayTek (c=居易科技|p=Jūyì Kējì) is a manufacturer of broadband CPE (Customer Premises Equipment), including firewalls, VPN devices, routers and wireless LAN devices. The company was founded in 1997. Their earliest products included ISDN based solutions, the first being the ISDN Vigor128, a USB terminal adaptor for Windows and Mac OS. This was followed by the ISDN Vigor204 ISDN terminal adaptor/PBX and Vigor2000, their first router. Their head office is in Hsinchu, Taiwan with regional offices and distributors worldwide. DrayTek was one of the first manufacturers to bring VPN technology to low cost routers, helping with the emergence of viable teleworking. In 2004, DrayTek released the first of their VoIP (Voice-Over-IP) products which has become one of their key areas. In 2006, new products aimed at enterprises debuted, including larger scale firewalls and Unified Threat Management (UTM) firewalls products however the UTM Firewalls did not sell in sufficient volume and the UTM products ceased development and production. DrayTek's product line offers business and consumer DSL modems with support for the PPPoA standard compared to the more the widely supported PPPoE for use with full-featured home routers and home computers without more expensive ATM hardware. PPPoA is used primarily in the UK for ADSL lines. Most Vigor routers provide a virtual private network (VPN) endpoint connection, either as LAN-to-LAN (to another router endpoint elsewhere on the Internet) or as teleworker 'dial in' for a single remote device. In 2011, DrayTek added SSL VPN facilities into their range. Although DrayTek do produce some products using Linux (in common with many other vendors), most of their products are based around their own proprietary DrayOS operating system. Linux products includes the Vigor 3900, 2960 and the VigorAP wireless access points, though each of these relies on a large proportion of proprietary code. DrayTek was floated on the Taiwanese OTC securities market in 2001.
