From: Papps on 11 Apr 2006 05:27 Hi, I want to disable/enable the USB ports. So, that no one can can access that device connected with that port. I tried the CreateFile method with no SHARE rights & read/write access ... but it was not useful. Again, i found usbioctl.h header file with WINDDK there we have a flag defines like IOCTL_INTERNAL_USB_ENABLE_PORT, IOCTL_USB_HCD_DISABLE_PORT and IOCTL_USB_HCD_ENABLE_PORT but i don't know how to use it. Can any one show me a light ?? Thanks in anticipation.
From: Maxim S. Shatskih on 11 Apr 2006 05:55 Find all devices of USB class and disable them using SetupDi calls. After this, the USB ports will be disabled for non-admins - and it is impossible anyway to hide them from admins. -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation maxim(a)storagecraft.com http://www.storagecraft.com "Papps" <pappu.kumar(a)gmail.com> wrote in message news:1144747674.309331.142710(a)u72g2000cwu.googlegroups.com... > Hi, > I want to disable/enable the USB ports.

From: Papps on 12 Apr 2006 00:33 Thanks Shatskih... But i have tried the SetupDi method & it didn't work for me. i had tried to enumerate all USB Devices using SetupDiGetClassDevs and then SetupDiEnumDeviceInterfaces. But it always returned as "No More Items". However, it works for the "ports" class and enumerate the COM1 port. But besides this for all the device classes it returns "No More Items". Can you tell me what can be the problem? surely, the ClassGUID is not a problem since i am using SetupDiClassGuidsFromName method to get that. Please help me out. If possible give some examples or API functions by which i can do this.

Enum devices themselves, and not interfaces. -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation maxim(a)storagecraft.com http://www.storagecraft.com
