Hi,
Does anyone know how to create a simple usb filter driver, all it
does is when it receives a specific DeviceIoControl command from my
application it will send a RESET command to the usb port for a
particular usb device so that it will effectively power cycle that
device ?
I am not too familiar with filter drivers, how do i create one and
how to install it so that its filtering all usb devices ?

Filter drivers are not hard -- there are several samples in the WDK.
However, you do not need a filter driver for this. You can send
IOCTL_USB_HUB_CYCLE_PORT to the hub to force a disconnect and reconnect.

Hi Tim,

thats a good idea, but AFAIK this is
not available on Vista and 7 anymore,...

Maybe a DICS_PROPCHANGE from Usermode
to the particular Device Intance can do the
job too, by using DIF_PROPERTYCHANGE
and class params "SP_PROPCHANGE_PARAMS::
StateChange" set to DICS_PROPCHANGE. This
will restart the device,...just maybe!

Regards

Kerem

@Tim,
Yes Kerem is right, IOCTL_USB_HUB_CYCLE_PORT is no longer available
on windows 7 according to the msdn docs, maybe there is something
else ?
I am just downloading the WDK, btw which example has a filter driver
on it ? also how do I install a filter driver so that its for all usb
devices and does it auto add itself as a filter to any new usb devices
that will be installed in the future ? or do I need to run the
installer again to add the filter to those new usb devices ?

@Kerem, I am already using DICS_PROPCHANGE but it only works if the
device is not being used or hung.

Ok,

what about this:

[WinUsb_ResetPipe]
http://msdn.microsoft.com/en-us/library/aa476447.aspx

I am not really sure if this
will work for you, since it
is not really clear to me what
exactly will be reseted here.
Maybe someone can explain,...

There are WMI classes but they say, that they
have not been implemented so far:
