driver

问题 now I want to add the function in my acpi driver . the function is:get the BIOS Notify . I search some doc, And Write code NTSTATUS XxxAddDevice( __in struct _DRIVER_OBJECT *DriverObject, __in struct _DEVICE_OBJECT *PhysicalDeviceObject ) { . . . status = STATUS_SUCCESS; DebugPrint(("AddDevice: %p to %p->%p \n",fdo,fdoData->NextLowerDO,PhysicalDeviceObject)); DebugPrint(("DeviceObject Flag = 0x%08x\n",fdo->Flags)); DebugPrint(("DevicePnPState = %d\n", fdoData->DevicePnPState)); { //PACPI

问题 I already read Creating a Virtual USB Device and Virtual USB device about creating a virtual USB Device. I am familiar with the Plug and Play handling by Windows as well as the driver mechanism. So far I understood that first of all I would have to create another device driver which is used for the virtual USB device. But I am still lost on the point what actually is the virtual device. How would I control the behaviour of my virtual device? Background: I develop a software which acts as a

问题 Complete error : Databricks Job timed out with error : Lost executor 0 on [IP]. Remote RPC client disassociated. Likely due to containers exceeding thresholds, or network issues. Check driver logs for WARN messages. We are running jobs using Jobs API 2.0 on Azure Databricks subscription and using the Pools interface for less spawn time and using the worker/driver as Standard_DS12_v2. We have a job(JAR main) which has just one SQL procedure call. This call takes more than 1.2 hour to complete.

问题 PagesPrinted field of job_info_2 not reliable for hp printers on windows 7, value depends on print processor I'm developping a print monitor, and for hp printer PagesPrinted is not reliable et has wrong values 回答1: The print driver for your printer is apparently calling SetJob with incorrect page count values. There's probably nothing you can do about that. Therefore, the only way to get an accurate page count is to parse the print data stream and count the pages yourself. The printer in

问题 i have made drivers work for the 2012 nexus 7, and a few other android devces. i just got 6 2013 nexus 7's and can not seem to get the drivers installed. i upgraded the software to 6.0.1. but i am unable to get to the screen shown here. adb does not find any devices. in ptp mode, windows finds most of these and assigns a usb driver 6.3.9600.17415 dated 2006. trying update the driver to add a more specific driver fails because windows does not know it's a phone. using have disk fails when

问题 After a whole day tracking down a memory leak in my VB.NET project, I have traced the cause to a bug with FileMaker's ODBC driver ! To reproduce you'll need a database you can connect to (I have mine hosted on Server Advanced 11.0.3, but you can also host it locally), and the ODBC driver registered/installed on the PC (I tested versions 11.3 and 12.0, and the latest 12.2). Start a new VB.NET WinForms project, add a button to the form and paste this code onto the button's click event: Using cn

问题 I am at a total loss on how to do what I think is a fairly simple and standard task: I am running SPSS 20 on Mac and want to connect to a SQL Server database on a remote server. When going to File -> Open Database -> New Query (The command names may be a bit off, my SPSS is in German and I'm just translating) it only shows myodbc as data source. I assume I have to add a driver for SQL Server however I don´t really know where to get it or how to install it as I cannot find it in the SPSS

问题 My machine apparently won't draw vertex lists in pyglet. The following code renders two identical shapes at different positions in the window, one using a vertex list and the other using a straight draw() . The one that's drawn directly renders fine, while the vertex list doesn't render at all. import pyglet window = pyglet.window.Window() w, h = window.get_size() vl = pyglet.graphics.vertex_list( 4, ('v2i', (100,0, 100,h, 200,h, 200,0)), ('c3B', (255,255,255, 255,0,0, 0,255,0, 0,0,255)) )

问题 I'm working on designing a USB peripheral which will occasionally connect to a Windows PC, and transfer a few KB of data in each direction. There will be a custom PC application that controls the data transfers, using a proprietary protocol (i.e. for the USB payloads). I see at the following link that Microsoft describes how to write a driver for a USB device. But do I need one? Developing Windows client drivers for USB devices The PC application is the only application that we intend to know
