请教有关USB虚拟串口的98驱动问题

  本人东拼西凑的完成了usb虚拟串口的驱动,目前在2000和xp下都能正常加载并通讯稳定,但在98下驱动却无法正常加载了,多次修改了inf文件都没有结果,由于无法正常加载,就根本无法进行驱动的调试,因此当前急需完成98驱动的加载....
    该驱动是wdm驱动, 2000和xp的驱动是在2000DDK下编译的, 98驱动是在98DDK下编译的.
    我把98下驱动的inf文件post出来, 请高手帮忙指点一下...

win98下的串口驱动应该是vxd驱动，你用wdm肯定不行了~~
一般是一个串口vxd+usb的wdm。

可否提供98下虚拟串口的VXD代码，参考参考

不行，因为有保密协议。不过跟driverstudio里的serial还是vcomm例子代码差不多。
