8 ehci \- Enhanced host controller driver
11 \fBusb@unit-address\fR
20 A USB 2.0 host controller includes one high-speed host controller and zero or
21 more USB 1.1 host controllers. The high-speed host controller implements an
22 EHCI (Enhanced Host Controller Interface) that is used for all high-speed
23 communications to high-speed-mode devices.
26 All USB 2.0 devices connected to the root ports of the USB 2.0 host
27 controller and all devices connected to a high-speed-mode hub should be routed
31 All full- and low-speed devices connected to the root ports of the USB 2.0 host
32 controller should be routed to the companion USB 1.1 host controllers. (OHCI or

196 The driver is unable to take control of the EHCI hardware from the
197 system's BIOS and aborts the attach. High speed (USB 2.0) support is disabled.
198 In this case, all USB devices run at full/low speed. Contact your system vendor

206 \fBLow speed device is not supported.\fR
214 The driver detected a low or full speed device on its root hub port. Per USB
215 2.0 specification, the device should be routed to a companion host controller
216 (OHCI or UHCI). However, no attached companion host controller appears to be
217 available. Therefore, low and full speed devices are not supported.

278 Note -
281 Due to recently discovered incompatibilities with this USB controller,
286 VIA chips may not be compatible with this driver. To bind \fBehci\fR
287 specifically to the chip and eliminate the warnings, and to enable USB2.x
288 support, a new, more specific driver alias (refer to \fBadd_drv\fR(8) and
296 # prtconf -vp | grep pciclass,0c0320
304 A more specific alias is 'pci1106,3104.' Perform the follow-
305 ing step to add this alias, then reboot the system:
