Intel Preps Linux For eUSB2V2 To Enhance USB 2.0 For Higher Resolution Laptop Webcams
Last September the USB Implementers Forum quietly published an update to the USB 2.0 specification..
The Embedded USB2 Version 2.0 "eUSB2V2" supplement to provide for better performance with significantly higher data rates to USB 2.0 while maintaining the low-voltage electrical interface. This eUSB2V2 update is intended to provide for more bandwidth for devices like integrated/embedded web cameras for allowing higher resolutions while maintaining low power requirements of 1.2V with Embedded USB. It points out this is optimized for performance, power and cost by using the USB 2.0 low-voltage, power efficient PHY and half-duplex link for the asymmetric camera bandwidth needs, avoiding the costly and complex full-duplex USB 3.x symmetric link and gigabit receivers.
