    I am tring to combine kbfiltr, moufiltr to 1 filtr driver which can
    filtr (as class filter ) both ps/2 kb and mouse. Is that ok?

    I always use nonpaged memory, but I sometimes got IRQ_NOT_LESS_OR_EQUAL
    error in kbdclass or mouclass when PnP START_DEVIC is received, why?

  2. As a professional driver developer you'll be familiar with WinDbg and be
    able to analyze a crash dump or do live debugging ;-)

    I have found the problem:
    I move the UpperConnectData out of device extension, and put it in
    Global variables: UppConnectData_keyboard, UpperConnectData_Mouse.
    Everything is difference just in DeviceExtension or not!!!
    I remember many people tell me that Global variables are NonPaged
    memory, (and I didn't use any progma to modified that attribute) why
    can I cause that error in mouclass/kbdclass?

    I just try it out, Can any one give an answer?
