USB CreateFile() Access is denied
-
When trying to open a USB keyboard device I get "Access is denied".
HANDLE hDevice = CreateFile (
lpDevicePath,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
FILE_FLAG_OVERLAPPED,
NULL);lpDevicePath is: \\?\root#rdp_kbd#0000#{884b96c3-56ef-11d1-bc8c-00a0c91405dd} If I do not ask for any access, i.e...
HANDLE hDevice = CreateFile (
lpDevicePath,
0,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
FILE_FLAG_OVERLAPPED,
NULL);I get a valid handle but I get "Access is denied" when I use it to call WinUsb_Initialize(). Any ideas? Thanks.
