Thanks for citing those sources. I wonder if Chris made a typo in his rules. I'm running U Cas Cas 7, 5 5 gold badges 65 65 silver badges bronze badges. Sadly, most of the cheapo serial adapters out there don't have unique serials : — benathon. Eliah Kagan k 51 51 gold badges silver badges bronze badges.

DSK names are still possible as well. On images for i. MX before V1. Depending on the host operating system, some registry patches might be required to make this driver work properly.

You can get the serial number of the FAT32 volume but it is trivially modified so useless to act as a license verification.

Buy a dongle instead. Add a comment. Active Oldest Votes. PaulH PaulH 7, 8 8 gold badges 64 64 silver badges bronze badges. How can i selected the one that i want. Get a list of usb conected and can choose between them. You'll save me if you know. Driver model.

Each type is described in the following paragraphs. Furthermore, CE drivers are implemented as either static libraries. Windows CE has been designed to directly use built-in devices. These devices are controlled by native drivers, which are intimately linked to Windows CE's core components. For example, the graphics, windowing, and events subsystem GWES module calls specific functions in the display device driver to render images at runtime. As one might expect, these functions are different from those required in the battery driver.

Hence, each native driver must conform to a specific, well-defined interface called the device driver interface DDI. These interfaces are explained in more detail later. Suffice it to say at this point that none of these interfaces can be changed by OEMs and that native drivers must fully support them. Native drivers are built as dynamic-link libraries, with two exceptions: the battery and the LED drivers are built as static libraries linked with the GWES module when a CE image is built because of their small size.

Native drivers are always loaded at boot time. Stream interface drivers all share a common interface. They are mostly used for controlling installable devices a scanner, for example , but a few are used with built-in devices, such as the serial port device driver, because the stream interface is better suited for those devices.

Stream interface drivers that control installable devices are typically accessed by applications. For instance, upon connecting a GPS device to the platform, the user will start a GPS-enabled application that will access and use the device. Microsoft chose to re-use an existing API specifically, the file API to enable the applications to access those drivers, instead of creating a new one. Consequently, stream interface drivers have been designed to expose a device's capabilities to the applications by presenting the device as a special file, which can be opened, read from, written, closed, and so on.

To be easily identified, stream interface drivers follow a unique file naming convention, which is composed of a three-letter prefix such as CAM for camera or BCR for bar code reader , a digit that identifies a specific device when multiple instances are available, and a colon.

The three-letter prefix can be any combination of uppercase letters, but it must be unique on a given platform. When an application opens a file that follows this convention, the file system module recognizes that a driver is being accessed and re-routes subsequent file system calls to the specific driver. In contrast to the native drivers, the stream interface drivers all share a common interface composed of 10 functions, or entry points, within each driver.

These functions, described in Table 1, closely match those found in the file API that are used by the applications. CreateFile combines the ability to create and open files. There is no OpenFile call. CloseHandle is then called to close the handle. An independent hardware vendor has the freedom to adapt these functions to the device's capabilities. The driver documentation becomes crucial for enabling developers to understand how to use the driver when writing applications that access the device.

Stream drivers can be loaded at various points in time. For built-in devices, such as an audio card, stream drivers are loaded at boot time via entries in the Registry.

For detectable devices a serial port implemented on a PC card for instance , the related driver is loaded at detection time, again using entries in the registry. Finally, applications can specifically request a driver to be loaded at run-time, by calling LoadDriver , for instance. Stream drivers are loaded, managed, and unloaded by the device manager module. Stream interface drivers typically rely on native drivers to perform their duties.

For instance, a bar code reader will rely on the serial port driver to physically access the device. In this instance, the bar code reader is called a client driver, and would use the Win32 file API to access the serial driver, the same way an application would.

Client drivers are useful because they encapsulate implementation details, such as processing data into a bitmap image, that applications do not have to be concerned about. The full USB host-side specification is supported on CE, including the various data transfer methods-control, isochronous, interrupt-driven, and bulk.

USB drivers can be implemented using three approaches. First, a USB driver can be implemented as a standard stream-interface driver, allowing applications to use the file API to access the device. NDIS drivers. Only a subset of the original specification, NDIS 4. As a result, miniport drivers are supported, but monolithic and full drivers are not. Fortunately, miniport drivers are largely source-compatible with those on NT. Microsoft provides various NDIS driver samples, and recommends porting an existing NT driver, if one is available, rather than creating one from scratch.

Device driver implementation. Adapting Windows CE to a specific platform is mostly a matter of developing the drivers for the particular devices the board features. The other aspects are to configure, build, and test the Windows CE image itself. Driver development, as I will explain, consists of implementing interrupt handlers driectly in the kernel and the code that access the devices the drivers themselves.

Interrupts are processed in unique fashion in Windows CE, as shown in Figure 1.
