4G闪存的6410-A使用使用上网卡上网

光与存在

大家好，这里有一块6410-a的板子，4g闪存，我在3.0.1内核源码的/driver/usb/serial/option.c中加入usb上网卡的产品号和厂商号之后编译下载启动，有时会出现/dev/ttyUSB0到ttyUSB4这5个节点，有时没有（很蛋疼）。就算是出现之后也不正常，还没拨号就会有无数个-84 和-71的错误码。在2440的2.6.28.7上面是可以用的，但是闪存太小，这个如何破？谢谢啦

现在就是想让这个4g NandFlash的板子能用vendor=0x05c6 product=0x9025的上网卡上网，3.0.1内核会弹错，option_instat_callback 这个是内核/driver/usb/serial/option.c中的一个函数。

在2440的2.6.28.7内核上该上网卡是可以用的，拨号没问题，跑起来很稳定。

该问题总算有了点眉目，在国外的论坛看到了相似的问题，http://www.draisberghof.de/usb_modeswitch/bb/viewtopic.php?t=410打开该链接需要翻墙的哦，简单粗暴的方法是下载个“自由门”。下面摘录两段与大家分享。

Josh：

1. There are Huawei problems introduced with the kernel series you use, due to a firmware bug. But they affected mostly the storage inte**ces of the switched devices, in many cases causing a reset which switched the whole thing back into the initial mode.
   
2. 
   
3. If that is the cause of your trouble - which I'm not entirely certain of - you could remove the usb-storage driver (after unmounting any automounted devices) and see if that helps. If so, look for a kernel above 2.6.31.5 where a workaround for the problem was included.

复制代码

Josh:

1. This is plain wrong, unfortunately. The example being the Huawei problem with kernel 2.6.32. It is a firmware bug that was not exposed on Windows and on Linux versions before; but when the storage driver was aligned with the official USB specification a little more strictly, the bug hit.
   
2. 
   
3. So, "working on Windows" is indeed no qualification for "bugfree".

复制代码

翻译一下第二段，大家不要莫笑我：
不幸的是，这（指下面的英文）是完全错误的。华为在2.6.32内核上的问题就是一个例子（弹出错误-71或-84），这是一个在Windows和以前版本的linux上不会暴露的固件（和我以前理解的”固件“二字不大一样哎）bug；但是当存储驱动程序与USB的官方规范更吻合，bug显露了。

2. The firmware/hardware failures can be excluded because these devices are working fine on windows.

那么问题来了，现在要让2.6.28的内核跑在这个4g闪存的板子上，我按照2.6.28的使用手测制作了sd卡，但是烧写的时候没有成功，记得提示是没找到设备，意思是这个内核不支持4G闪存的这个板子吗？修改一下可以成功吗？在看尝试中。哪位大神给点建议呀，不胜感激。。。。。。。。。。。。。。。
