Hi!
Is there a way we can send usb vendor specific requests to a device from
user-mode applications or from a driver which is not in the usb driver
stack.
Thanks

Hi Fareed,
One way is Device I/O Control. You can define your own IOCTL code and use
it for sending messages from User Mode application/other driver.

Hi,
Here i am giving an example to send vendor specific command to USB
driver from ur driver.
It may help u.

Hi Prasad,
Our device has only one endpoint(interrupt).Hence
urb->UrbControlVendorClassRequest.RequestTypeReservedBits =
REQUEST_TYPE_ENDPOINT_0 seems fine but I am not able to get
urb->UrbControlVendorClassRequest.Value which you are setting to
BLUETOOTH_DEVICE_CLASS.
One more thing is once you build this URB how are you sending this
to the USB stack,is it that you are building an IRP_MJ_WRITE,passing the urb
in nextStack->Parameters.Others.Argument1 and then calling below driver ?.
Actually my device responds back for this request,how do i receive the
data sent by the device in response to the command i am sending to it
?(I am filling the command to be sent in
URB_CONTROL_VENDOR_OR_CLASS_REQUEST .TransferBuffer).
Thanks.
Best Regards,
Sai Prasad

No - not without a driver in the USB stack. However, building a driver that
attaches to the stack is not that hard and (as the other poster pointer out)
then you can simply expose an IOCTL that can be called from user mode with
the vendor request descriptor as its data.

HI Sai,
BLUETOOTH_DEVICE_CLASS, this is bluetooth device specific value.
When ever bluetooth device recieve request having this value, interpret it
as command. It will be different in ur case. See ur device’s specs.
After building URB, build IOCTL_INTERNAL_USB_SUBMIT_URB IRP
and pass urb in nextStack->Parameters.Others.Argument1 = URB
, Parameter.
For building IRP u can use IoBuildDeviceIoControlRequest() finction.
call ioDriver() to submit IRP.
REQUEST 0x00 /*Zero When sending other than standard request*/
See USb spec chaptor 8 for more details.
For receiving data back from device, read device’s detailes.
Ur device has only interrupt endpoint so build
_URB_BULK_OR_INTERRUPT_TRANSFER URB with interrupt pipe handle pass this urb
to lower driver using IRP_MJ_INTERNAL_DEVICE_CONTROL IRP.

Can I make the PNP Manager call IRP_MN_REMOVE for my device?.From an
Application I think it is possible.
My requirement is our Application sends me an IOCTL to remove the device in
which case I should make the PNP Manager to send me
IRP_MN_QUERY_REMOVE_DEVICE and IRP_MN_REMOVE_DEVICE.

Hi All,
I am writing a Hid Mini Driver. When the Io Manager calls my Add Device
function it will provide a pointer to the functional device Object( FDO) of
the HID Class. But How can I get hold of the HID Class’s PDO.
Thanks in advance.

SetupDixxx functions inform the PNP Manager from Application part…but
what I want is to inform from Kernel Mode…I have framed an IOCTL which
would be received by my Plug and Play Driver and would call
IoInvalidateDeviceRelations passing the PDO of my device stack.The DDK
Documentation says that I should receive IRP_MN_QUERY_RMOVE_DEVICE after
that but I don’t see any PNP Minor IRP coming to my driver.Any
Clues/Suggestions ?
Thanks,
Best Regards
Sai Prasad
