![]() ![]() It should work for ISO-OUT transfers, like audio. This code is new and hasn't been used with many different EHCI or USB 2.0 transaction translator implementations. depends on USB_EHCI_HCD & EXPERIMENTAL.(on/off) Full speed ISO transactions (EXPERIMENTAL).To compile this driver as a module, choose M here: the module will be called ehci-hcd. If you configure EHCI, you should probably configure the OHCI (for NEC and some other vendors) USB Host Controller Driver or UHCI (for Via motherboards) Host Controller Driver too. Ports will connect to EHCI if it the device is high speed, otherwise they connect to a companion controller. EHCI controllers are packaged with "companion" host controllers (OHCI or UHCI) to handle USB 1.1 devices connected to root hub ports. At this writing, the primary implementation of EHCI is a chip from NEC, widely available in add-on PCI cards, but implementations are in the works from other vendors including Intel and Philips. If your USB host controller supports USB 2.0, you will likely want to configure this Host Controller Driver. The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0 high speed (480 Mbit/sec, 60 Mbyte/sec) host controller hardware. (on/off/module) EHCI HCD (USB 2.0) support.Howto configure the Linux kernel / drivers / usb / host
