    <p>We need more information about the device to point you in the right direction, but here are a few steps to get you started:</p> <ul> <li>register with Microsoft Connect so you can download the Windows Driver Kit</li> <li>register with <a href="http://www.osronline.com/" rel="noreferrer">osr-online</a> as you'll find great articles, plenty of information, and a newsgroup dediciated just to Windows drivers -- this place is a goldmine</li> <li>buy <a href="http://rads.stackoverflow.com/amzn/click/0735623740" rel="noreferrer">Developing Drivers with WDF</a>, which will help you make sense of driver development on Windows and give you a good foundation to read articles from OSR and Microsoft</li> <li>Hope that you can use UMDF (user-mode drivers) as you can use C++ and just write COM code. If you're doing anything with USB that requires kernel-space....you've got a lot of reading and learning to do for the next year!</li> </ul> <p>To answer your question on versions, the Driver Kit has tools that will help you manage creating different drivers. If you write a good driver, it should run on all three OS with no problems, and the differences will just be in the config area (not the binary)</p> <p>Basically, it depends on how complex your device is. What type of driver are you trying to write? File system? MP3 player? Camera? Modem?</p> <p>If you end up having to write a kernel mode driver, let me know and I can point you to some good articles and what not. </p> <p>I should also add that for around US $5,000, you can buy a license for <a href="http://www.jungo.com/st/windriver_usb_pci_driver_development_software.html" rel="noreferrer">WinDriver</a>, a tool that takes all of the hard stuff out of driver development. You can use C++ or C# user-mode code to communicate with their driver that is custom generated for your device. This is the way to go if you have a tight deadline.</p>

    2. COThe latency is going to heavily depend on your hardware's USB controller. If I were you I'd throw together a test UMDF (user-mode) driver first and see if it meets your latency needs. Forget about nice interfaces and what not, just get the I/O functionality implemented and a Win32 test app for pushing and pulling data. With the book I mentioned above you should be able to have a basic driver ready in about a week. The advantage of UMDF is that it is quite easy to implement and easy to debug as you don't need the kernel debugger. You can always go with KMDF if UMDF doesn't cut it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
