Hi all !
Where can I found a driver source code for an USB Blocker ?
I need make a tool for block USB devices… like memory cards, external
Harddisks, etc…
Any example source code are welcome…
Thank you
I find epoxy poured into the USB connector works quite well…
Alternatively, a quick google leads to several existing implementations (so
why build another one!) search for “protect usb port” for example…

There’s 99% of one in the DDK. Take the USB bus filter driver and fail
IRP_MN_QUERY_DEVICE_RELATIONS.
Works for me.

I hope you are dereferencing each PDEVICE_OBJECT that was reported
successfully in the list before you failed it, otherwise, there will be
a lot of leaked device objects out there.

Well, if you fail it on the way down, no devices will get reported at all.

That still doesn’t work. The rules for QDR is to process the irp on the
way down the stack. What if there was another filter on top of yours
which enumerated a child? You still need to see if there are any
devices in the relations that you need to deref if you fail the request.

You need to write a filter driver. Decide what device object resides at
the lowest common level for all the devices that you want to block, and
put a filter over it.
No, there’s no sample that I’m aware of,

heya,
i’ve made the same tool long ago, its really easy. Unfortunately, i
can’t find the source anymore.
Anyway, i attached an upper filter to the USB controller via a properly
crafted .inf file (using the USB controller GUID), then in the
StartDevice path of the filter i just get the device description of the
device to be started, compare with the guids i want to block (mass
storage devices, printers, whatever you want), and if it matches i
simply complete the IRP with STATUS_UNSUCCESFUL.
Hope it helps…

This only works for devices which install under the usb device class
(the base of usb mass storage, printing support, hubs, generic parent,
controllers, etc). this won’t work for any device which installs under
its own device class. For instance, install a keyboard and view the
device tree in device manager by connection. The base device enumerated
is installed in the HID class, so you installing as a usb device class
filter will not work (in all cases at least)
