[破解]CIOS usb2放出(支持USB 2.0)

wiiwaker

那啥,承接着cIOS36 rev08的热浪......其实是在这之前,KWiirk放出了cIOS USB2 beta1

This program is a modification of custom ios module by neimod, implementing a usb2 (ehci) driver instead of the oh0 module. Requires an IOS that accepts fake signatures, in other words 3.2.

Description:

* added libcios, to avoid (source) code duplication between modules and iostester
* corrected some bugs in the original code (stack address pointed to the begginning of actual memory allocation, but needed to be at the end.)
* added tinyehci, a minimal generic ehci driver based on linux ehci-hcd driver.
* added oh0module, which implements the oh0 ios messages with tinyehci, and new usbstorage messages for even better
* added patchmii installer

Driver limitation:

For the moment this driver is EHCI only. This means only usb2 devices would work. I actually only tested hard-drive and sdcard reader (my USBkey wont work). So forget keyboard, mices, and other USB1.1 toys for the moment. Bluetooth keyboards/mouses might work independently. It would not be so diffi*** to connect a OHCI driver once it is done to get that usb1.1 support. Grub2 implements a small OHCI driver which could do the job (dont wait for me to do it, all source code is GPL). The lack of a real usb stack means the driver also lacks hub support. Anyway, the USB2 hubs "TT" mechanism is a bit complicated, and would need a lot more work. The driver doesn't implement the scheduled pipes, ie interrupt and isochronous pipes, which would be needed for highend webcams (I cannot think of other usb2 devices type that uses such pipes.)

Todo:

* Performances are still limited to 4MB/s on a HD which can do up to 119MB/s with dd on linux.
* compatibility: I got one lowend USB key, which doesn't work (stalled at the first bulk message)
* more testing is needed, but for now it seems more stable than nintendo's oh0 driver (which crashed when doing a performance test..)

最后放出由nicksasa释出的重编译的使用USB 2.0的homebrew程序

这个有啥用呢？？问一下？？？

简单的说提高了接口的读取速度，直接的为 多媒体播放器 叶就是 rmvb播放速度上升，深远的 为以后的 hdl 提供了 硬件支持

原来播480P的片子卡是不是接口速率的问题，有人试过新的播放器放480P的片子么？

jibo

RM和速度无关吧，播放几百M的VOB都不卡，为什么播放几十M的RM就会卡，应该是WII的CPU问题。

jtgongcm

我说的480P的片子不是RM的，是MP4。播放比较卡。RM估计是CPU的问题，软解码耗CPU啊。

720的avi原来也不卡，usb2.0应该是为hdl准备的吧，和视频应该关系不大。。。。。

USB 1.1的速度也足够播放720P的了,wii...我还是安安心心当游戏机使好了
