drivers

问题 We have a few driver packages that we pre-install in the driver store on Windows with SetupCopyOEMInf, following Microsoft's suggested procedures. This process has worked properly for years; no problems on XP, Vista, 7, and even 8. While evaulating Windows 8.1 RTM, we found that our drivers were no longer pre-installing. Checking the setupapi.dev.log, I found: !!! sto: Failed to query boot critical status of device class. Error = 0x00000002 and later: !!! idb: Failed to query inbox status of

问题 Need an idea to write a code to authenticate users before they send the commands to print. Initial idea is to create a windows service which could bypass the call to the printer driver and can open a form for login credentials. so that only the authenticated users who qualifies the monthly quota for printing the pages could access the printer. Please share your views whether this approach is feasible and how this can be achieved. 回答1: You can monitor the Win32_PrintJob WMI Class or the

问题 Same situation as described in Preinstalling Driver on Windows 8.1 Fails. But is there a fix how to reinstall the same driver package (no guid change) without reinstalling 8.1? Situation: On a fresh Windows 8.1 installation (no upgrade from 8.0), our USB devices can't be installed. Behavior can be reproduce with a VM: create registry entries with class guid from inf file to show correct USB icon and create own group in device manager: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class

问题 I configured visual studio 2008 for compiling drivers, but still showing lots of syntax errors for header file for ctype.h and excpt.h 回答1: I configured with following settings : Setup Visual Studio 2008. Setup ddk (wdk). Add to Visual Studio paths DDK include files, libs and bins, In VS goto tools ->options->Project and solutions->VC++ directories-> add path to your ddk Include files,Executeable file,Library file Create new empty "Win32 project" and add source file (i.e. Hello_World.c).

问题 How do I install a hardware driver ( inf file ) using C++? Platform : Win32 回答1: The process is usually called pre-installation . (The normal install process is triggered by the arrival of an hardware device.) The relevant functions can be found in <DIFxAPI.h> from the DDK. You probably want to call DriverPackageInstall() . The expected return value is ERROR_NO_SUCH_DEVINST [sic] as there won't be such a device yet. There's some 64 bit funkyness: you can't install a 64 bits driver from a

问题 I am trying to get an accurate understanding of how Java's Service Provider Mechanism works to locate the appropriate JDBC driver. Here is what I have so far: Since Class.ForName is no longer used to explicitly load a JDBC Driver , Java would know what type driver it needs from the database url string that one passes to the getConnection method. For instance the database url to connect to a oracle database would be something like this: public static final String DB_URL = "jdbc:oracle:thin@/

问题 I am running a series of JUnits using Apache ANT using JDK 1.5. All JUnits that use an Oracle JDBC driver give the UnsatisfiedLinkError shown below. What native library is it looking for and how do I solve this? What should the PATH variable contain? java.lang.UnsatisfiedLinkError: oracle/jdbc/driver/T2CConnection.t2cGetCharSet([CI[CI[CI[CII[SLoracle/jdbc/driver/GetCharSetError;)S at oracle.jdbc.driver.T2CConnection.getCharSetIds(T2CConnection.java:2957) at oracle.jdbc.driver.T2CConnection

问题 There is a code example on MSDN which uses WMI to enumerate all of the dependencies for a particular service: http://msdn.microsoft.com/en-us/library/aa393673(v=vs.85).aspx This is great...but i've discovered that the dependencies it discovers might not all be of the same type. I was expecting all dependencies to be of type Win32_Service...but sometimes you will find that a dependency that is actually a driver (Win32_SystemDriver). So..my question is simple - how do I adjust the MSDN code

问题 This question was migrated from Unix & Linux Stack Exchange because it can be answered on Stack Overflow. Migrated 2 years ago . I'm learning how to develop a simple driver for a card connected to the USB1 serial. I wanted to know how the kernel understand that my device needs to be mapped as /dev/ebbchar. How to change to /dev/ebbGV? and if i connect another device why i dont view /dev/ebbchar but /dev/tty0? thanks. In short how kernel do to understand that board connect to USB1 is ebbchar
