Thank you!! buffering8331-Jul-09 9:48 buffering83 31-Jul-09 9:48  have Good day~ hi My english is a little. anyway, nice to meet you~~ and give me your advice anytime~ Accessing my gps module in my Nokia N82 frankvdhorst31-Jul-09 4:17 frankvdhorst 31-Jul-09 4:17  Hello, I am new here and I have a question. I am using c# express edition, and I want make an application that can use my internal gps module from my nokia n82 by USB connection or by bluetooth connection(My pc has a bluetooth ability and my phone also) . Is this even possible? And if this is possible can anyone give me a short step by step plan. I am really curious if it is possible to interface with my Nokia N82 gps module and get gps coordinates and very eager to use this in my application. Thanks for any reply Frank Access denied opening raw pdo sinosoidal30-Jul-09 5:19 sinosoidal 30-Jul-09 5:19  Hi, I'm trying to set up raw pdo and i'm basing myself on the kbfilter example. I used the code on the sample to put it on my device driver based on the hidfx2usb sample. However, when I tried to open the raw pdo thru its guid I have an access denied. How can i debug such error? How can I know why is it having an access denied? Any tips? Thanks, Nuno Re: Access denied opening raw pdo Randor 3-Aug-09 7:33 Randor 3-Aug-09 7:33  Hi sinosoidal, I believe my reply to your previous question may shed some light on your situation.

I'm trying to do this because i'm writing a driver which is based on the hidfx2usb sample and it maps the usb device into a hid device. the thing is that i can't access directly the device from the user space because the hid class blocks the requests. i've been told to create a raw pdo device to have direct access to the device. i had a look to kbfiltr and there is created a pdo, but the example registers a pdo for a keyboard and my device is a usb device. my question is about how to associate the pdo to the usb device. in the example the base string for the pdo registering is this: #define KBFILTR_DEVICE_ID L"{A65C87F9-BE02-4ed9-92EC-012D416169FA}\\KeyboardFilter\0" How should I register a pdo for a usb device?

Now it's almost time to go to production. For production we need to copy my program and database to a USB stick, pull the next available serial number from an Excel spreadsheet (or another database), open the database on the USB stick and record the serial number there and in the Excel spreadsheet. Simple, simple code, right? Yeah... until we think about the fact that we're going to be mass producing these USB sticks several at a time. I know the first order is for like several hundred so there's definitely not time for someone to sit there and do this one stick at a time. However, I can't imagine that this is something new. There has to be some combination of hardware/software out there that will not only copy the files to the USB stick (we've found several of those) but also allow us to put a unique identifier on each stick. Ideally I'd like to be able to put the serial number in the database but if it's a text file or some other file format that would probably work too as long as I can figure out how to access the number because it has to be something that my program can show the user. Help? Ideas? Thanks!!!

So that is also the time you do your specialization stuff. 2. You should be aware that most, if not all, USB sticks contain a unique ID that is (a) easily accessible from code (WMI), without requiring admin rights, and (b) is unique within each vendor, and very likely to be globally unique. So maybe a better idea is to keep the content of all the sticks identical, and tell them apart by the ID number they already have.

Re: USB mass production each with their own serial number Hypermommy30-Jul-09 1:02 Hypermommy 30-Jul-09 1:02  We ended up finding a company called NexCopy and according to their salesman they can do what we need to do. They copy stuff over in two stages, apparently. The first stage is the same for every stick that's plugged into the unit and that's when we'd copy over our program. Then they pull information from separate staging files for separate sticks. So stick number 1 would pull additional data from folder #1, stick #2 from folder #2, etc. That's where we'll put our serial number. Thanks all! Denise "Hypermommy" Duggan How to access device context data? sinosoidal28-Jul-09 3:39 sinosoidal 28-Jul-09 3:39  Hi, I'm developing a kernel mode driver to handle a USB device. The device is always sending packets of data. That data, after 16 packets becomes 1 entire frame. That frame will then be delivered for a next phase processing. This frame is kept on the device context structure. However, I also would like to retrieve that data from the user space. I want to create an application to visualize that frame. The question is... what are the mechanisms to communicate from the kernel side to the user side? How can I access device context in order to get this piece of data from the kernel side in the user side? I hope to be clear enough, Thanks, With my best regards, Nuno Re: How to access device context data? nastytoe30-Jul-09 12:05 nastytoe 30-Jul-09 12:05  Thanks for clearing this up for me. I never understood how to access the data like this.

Windows Mobile Device with Webcams Plugged In henry00023-Jul-09 15:00 henry000 23-Jul-09 15:00  Hi everyone, I am exploring the possibility of plugging webcams/cameras (preferrably any webcam/camera - so I don't get tied to a particular hardware vendor) into a Windows Mobile 5 or 6 device, and write a piece of software app that allows user to click a button in that software app to get the plugged-in webcam/camera to take pictures or video streams. So, I will need to know if this is possible to write a software app to do so on Windows Mobile 5 or 6 platforms? .NET is preferred but not essential. What exactly do the webcam need to adhere to (for example, TWAIN)? USB Video Class 1.1? Bluetooth? I had a look on the internet but no luck so far. Any pointers will be welcome. Thanks p.s. I also posted the same message on Stackoverflow... Custom Device Driver / Editing Device Driver Soundshark20-Jul-09 4:34 Soundshark 20-Jul-09 4:34  Hi I have a fair knowledge of electronics and have decided to under take my self a small project and build a multi function foot switch for controlling media players on stage for when im singing. I have made my prototype from an old usb keyboard and buttons removed from a old serial mouse. I may change this later date to use a usb game pad or even build a whole new board based on the PIC18F4550 Now here's the tricky bit I have a small app called RM-X media edition which allows me to assign any received input as a control, currently SPACE - PLAY/PAUSE 1 - BACK 2 FORWARD I picked these because they where easy and used the same common ground on the keyboard controller. What im hopping todo is edit the standard driver files that windows uses for this device to allow it to show as its own device i.g "Soundshark foot switch" The second part is to rename the commands as it is windows see the inputs as keyboard strokes I want to edit these again to read as there respective functions in the RM-X software. I hope this is enough information and makes sense Any help at all on this matter would be fantastic. Thanks Anthony Re: Custom Device Driver / Editing Device Driver Luc Pattyn20-Jul-09 6:20 Luc Pattyn 20-Jul-09 6:20  Hi, I don't know enough to give you definitive answers, however here are some thoughts: - as you are using a (modified) keyboard without any special driver, it is using the standard USB keyboard driver and I don't expect you can't do anything related to its name or its character table; it will show as whatever device the manufacturer decided it was (unless you can reprogram the microcontroller they used). - as an alternative way to personalize it, you would need to create your own driver. - I've done some PIC-to-PC interfacing in the past, using RS232C, not USB; I would be interested in learning how to do similar things with USB. - rather than using normal keys, I would choose some of the function keys. That would much less disrupt your other programs. Or you could try and figure a way to get a key combination, say a modifier key (CTRL/ALT/SHIFT) and some other key; problem is you have to hold down one, press the other, release the first. You can't hold down the modifier key, that would really upset everything.

Re: Custom Device Driver / Editing Device Driver Soundshark20-Jul-09 6:27 Soundshark 20-Jul-09 6:27  yeah may be the best option was just hoping to try and make it a stand aloan device, Only way i though about getting a round it using a standared driver was to install manually or selct update drive and selct my driver rarther then the installed one to superseed it other option is to use a cheap usb gaming pad or as i said befor build my own controller from scratch if i can find a basic design 3 buttons would be plenty.
