移植5.0至6.0的USBFN所遇到的问题 [复制链接]

重操旧业，移植5.0BSP至6.0，还是比较顺利的
不过的USBFN驱动上一直过不去，Client是用serialusbfn.dll,

大家帮我看看我的打印信息，看看能不能看出问题所在

可能原因：
1、源文件“usbfndrv.cpp at line 531”需要检查。
2、源文件“cserpdd.cpp at line 531”需要检查。
3、“Init() failed ”初始化失败的原因也需要注意。
4、“couldn't activate: prefix COM, index 5, dll serialusbfn.dll, context 0xd02dd068”为什么该文件不能激活？这个也要考虑。
把上面的4个问题搞定，你从5.0移植到6.0应该就大功告成咯，呵呵，我是来学习滴…此外，Platform Builder 6.0的帮助文档中有与移植相关的文档介绍，内容非常翔实相当详细…
