Ports 51 will connect to EHCI if the device is high speed, otherwise they 52 connect to a companion controller. If you configure EHCI, you should 53 probably configure the OHCI (for NEC and some other vendors) USB Host 54 Controller Driver or UHCI (for Via motherboards) Host Controller 55 Driver too. 56 57 You may want to read <file:Documentation/usb/ehci.txt>. 58 59 To compile this driver as a module, choose M here: the 60 module will be called ehci-hcd. 61 62config USB_EHCI_ROOT_HUB_TT 63 bool "Root Hub Transaction Translators" 64 depends on USB_EHCI_HCD 65 ---help--- 66 Some EHCI chips have vendor-specific extensions to integrate 67 transaction translators, so that no OHCI or UHCI companion 68 controller is needed. It's safe to say "y" even if your 69 controller doesn't support this feature. 70 71 This supports the EHCI implementation that's originally 72 from ARC, and has since changed hands a few times. 73 74config USB_EHCI_TT_NEWSCHED 75 bool "Improved Transaction Translator scheduling" 76 depends on USB_EHCI_HCD 77 default y 78 ---help--- 79 This changes the periodic scheduling code to fill more of the low 80 and full speed bandwidth available from the Transaction Translator 81 (TT) in USB 2.0 hubs. Without this, only one transfer will be 82 issued in each microframe, significantly reducing the number of 83 periodic low/fullspeed transfers possible. 84 85 If you have multiple periodic low/fullspeed devices connected to a 86 highspeed USB hub which is connected to a highspeed USB Host 87 Controller, and some of those devices will not work correctly 88 (possibly due to "ENOSPC" or "-28" errors), say Y.

On most non-x86 systems, and on x86 hardware that's not using a 212 USB controller from Intel or VIA, this is appropriate. If your host 213 controller doesn't use PCI, this is probably appropriate.
