I'm exploring the UMDF framework as I try to develop a UMDF driver for a USB device.
I've used the UMDF sample "usb/fx2_driver" final step as starting point, comparing various steps in the sample and removed things specific to the fx2 device that I don't need, such as the read/write queue functionality and 7-segment handling.
My driver is supposed to use the control endpoint only so the user application will use ::DeviceIoControl calls for communicating with the driver, thus no ::ReadFile or ::WriteFile calls will be made.
I've managed to set up the debugging environment in a way that I'm able to break into the driver when it loads using WinDbg and attach to the WudfHost process.
My problem is that my driver fails to start, error code 10.
When I try to debug it everything according to my knowledge (which is limited in this area...) looks fine until I hit a breakpoint in CMyDevice::OnReleaseHardware.
The call stack prior to my code looks like this:
007ffd98 1a9208c6 WUDFx!WdfPnpHardwareCallback::ReleaseHardware+0x26
007ffda0 1a91e887 WUDFx!CWudfPnp::PnpEventFailedOwnHardware+0x10
007ffdbc 1a91ed8a WUDFx!CWudfPnp::PnpEnterNewState+0x8e
007ffde8 1a91ee7a WUDFx!CWudfPnp::ProcessEvent+0x2a2
007ffdfc 1a90d65b WUDFx!CWudfPnp::OnStartComplete+0x27
007ffe18 1a90d790 WUDFx!CWdfDevice::ProcessPnPCompletion+0x3c
I haven't got a clue why PnpEventFailedOwnHardware is called.
Most likely I've failed to do something that I was supposed to, but what steps should I take in order to figure out what?
I don't know whether this is relevant or not but !umirps tells me that I have one pending IRP at 0x9f008 and !umirp 0x9f008 gives me this:
Error in reading UM IRP at 0x0009f008
UM IRP: 0x0009f008 UniqueId: 0x0 Kernel Irp: 0x0x89b9b698

Completion:

I haven't found any information on the net that I've found to be helpful in overcoming this problem.
The documentation for UMDF is rather limited, to say the least...
Thoughts and/or ideas anyone? At this point I'll run for every ball tossed in my direction....

Due to my lack of experience from WinDbg, I didn't realize that CMyDevice::OnPrepareHardware returned an error.
I used the mouse to hover above the local HRESULT variable and I was told that the value was 0x00. When I checked the register (EDI) that is used for the return value I found it to be something else (0xd0000001).
After I corrected this the driver starts up nicely.

Thanks for taking the time to modify your post to "resolved" AND posting the solution. If only everyone did that 
Cheers,
Sebastian

Well, thank you for noticing! 
As this is a searchable forum, this is how I think it should be done. Otherwise there wouldn't be any benefit for others.
Just following my own guidelines...

I attempt to use the kmdf to write a DFU(Device Firmware upgrade) driver and need to open/read an upgrade image (an normal file on disk) in the driver (maybe in the callback EvtDOEntry()). Is this possible to do this? Any suggestion would be appreciated.

It can be done (Using files in a driver[^]) but it must run at passive level. Also, if your driver is boot load, be careful that the storage stack and file system has been loaded before you.

Dear friends,
I have a query. And I hope you can solve it.
You are heartily requested to help me.
I have to make an application for employee attendance recorder using THUMB (Finger Print) scanner (Biometrics). using VB.NET
I dont have idea about that hardware and how to relate with our application.
First of all I system will keep Database of thumb impressions of all employees.
Then employees will note their attendance by their thumb on scanner. System will identify and match the thumb print.
If it is matched then corresponding employees record will be updated for (As he/she is present for that date) otherwise it will give an alert that invalid employee,
I think you got my theme. You have solved such problem. and I hope you will cooperate me this case.
You are kindly requested to guide in this.
Thanks.... I am waiting for your reply.
Thanks,

Hi,
I have a Intel Core 2 Duo Machine that keeps on resetting at irregular intervals. I have reloaded the OS but to no avail. Then I loaded the Intel Hardware Monitor and see that I may have two problems:
1. The CPU is a bit Hot (57 Deg Celcius - according to the Monitor this is yellow alert)
2. CPU I/O Voltage is a bit Low at 1.26V (Should Be 1.5V)
It Would seem that I need to replace one or more fans in my box and also replace my Power Supply (500W).
Is my deductions corrent and is there maybe anything else that I should look at?
|

Sounds good to me. Although I think its more likely to be the overheating thats causing your problems. I would replace the fans first, and if that doesn't help then go ahead and replace the power supply.
Trinity: Neo... nobody has ever done this before.

If you have a homebuilt/small shop built box you might have an option to adjust the voltage in the BIOS. If only one voltage is off significantly it's your mobo's power modules that're bad not the PSU. The PSU only provides +3.3v, +/-5, and +/-12V to the board. The various lower voltages that the chips require are produced by the the mobo itself using DC-DC convertors.
You know, every time I tried to win a bar-bet about being able to count to 1000 using my fingers I always got punched out when I reached 4....

First you should check you power supply. I recently had a similar case with some weird values at voltages.

If you want, I'll show you how to do this using VB.NET and one DLL.
And if you good at C#, it is not difficult to convert VB.NET to C#.
