  • Question

  • i'm writing a virtual multi-touch driver of vhidmini-based for windows 7. but,when i succeed to report touch_msg to system,problems came, after mouse was moved,system stops to receive any msg of multi-touch, and seems multi-touch device was completely disappeared(system still display multi-device was inserted).
    but i using hclient to read report was succeed..
    (and when i open a software(pop a prompt to comfirm),then my driver seems working well,even if mouse was moved,but when i close prompt,my driver stops working)
    i know usb_mouse was higher priority.. but i wondering the answers how can i restart my driver without restart system. or somebody tell me where's vhidmini of kmdf version? thanks friends. my driver was a vritual hid-based driver~~~~
