At the time of this writing, 15b3c29d85SJesper Juhl the primary implementation of EHCI is a chip from NEC, widely available 16b3c29d85SJesper Juhl in add-on PCI cards, but implementations are in the works from other 17b3c29d85SJesper Juhl vendors including Intel and Philips. Motherboard support is appearing. 181da177e4SLinus Torvalds 191da177e4SLinus Torvalds EHCI controllers are packaged with "companion" host controllers (OHCI 201da177e4SLinus Torvalds or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports 21b3c29d85SJesper Juhl will connect to EHCI if the device is high speed, otherwise they 221da177e4SLinus Torvalds connect to a companion controller.
