Invoking the device driver

Hi
I have written a non-STREAMS character device driver for Solaris...It passes the 'modload', 'modinfo' and 'modunload' test successfully.....
Now, I have the xxopen(), xxclose(), xxattach(), xxdetach() entry points in my driver.. I am also using the ddi_create_minor_node() function in my xxattach() routine but I do not see any device node being created in /devices.
I am trying to write a sample application which will invoke open(2) and close(2) system calls... What is the path that I provide to the open(2) system call for oepning the file.. also, exactly when will the device node get created in the /devices directory.
also, how can my user-land application invoke the xxattach() routine of the driver ??
Awaiting urgent replies..

Thanks a lot.... My driver is for a physical device, and hence is not a pseudo driver.
somebody told me that for a device driver meant for a real, physical device, I need to supply a set of PCI IDs the driver should bind to.... Can you tell me where to specify these PCI IDs and how do I get to know more about them ? (Basically, I want to know the process of creation of device nodes under /devices directory and symlinks in the /dev directory for 'real hardware' drivers and not pseudo drivers)
Also, upon copying my driver to /usr/kernel/drv and issuing 'add_drv' results in the following message
"Driver (vmci) successfully added to the system but failed to attach"
Running "dmesg | tail" tells me that only the init() routine was called when I issued "adddrv" command......
I then tried commenting the entire block of code inside xxattach() but it still gives me the same error upon issuing "add_drv".. Is it because I need a .conf file (containing the PCI IDs) before my driver is able to attach to the device ??

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing.

I'm having the error "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)" and I can't read/write CDs/DVDs. When I try to update the driver I have the message that it is already up to date.
I can't find the driver to dowload and try to fix the problem. Where can I download it or solve somehow my problem?

Hello jlb1977,
Thanks for using Apple Support Communities.
For more information on this, take a look at:
iOS: Forgotten passcode or device disabled after entering wrong passcode
http://support.apple.com/kb/ht1212
place the device in recovery mode and restore it to erase the device:
Disconnect the USB cable from the device, but leave the other end of the cable connected to your computer's USB port.
Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to shut down.
While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on.
Continue holding the Home button until you see the Connect to iTunes screen.
iTunes will alert you that it has detected a device in recovery mode. Click OK, and then restore the device.
Best of luck,
Mario

Windows: how do I update the device driver for my video/display adapter?

Installed video drivers may not always support the functionality of the latest Flash Player. If Flash Player does not function correctly, updating the video drivers to the latest available version is one of the first steps to try. Below are instructions how to update the video drivers on Windows systems.
identify the manufacturer and type of your video card
open Device Manager: Start | Run | enter devmgmt.msc
open the Display Adapters drop-down; this will show you the installed video card:
identify the device driver version
right-click on your display adapter entry and select Properties
click on the Driver tab; this will show you the driver version and date:
go to the device manufacturer's support site and download the latest driver
NVIDIA cards: NVIDIA driver download page, or auto-detect
ATI cards: ATI driver download page, or auto-detect
Intel cards: Intel driver download page, or auto-detect
Matrox cards: Matrox driver download page
VIA cards: VIA Arena driver download page (redirects to 3rd-party download site)
SiS cards: SiS driver download page, or auto-detect
S3 cards: S3 driver download page, or auto-detect (option 2 on the download page)
follow the instructions on the manufacturer's support site
Note: some of the auto-detect utilities linked above will only run on Internet Explorer.

3)We tried to compile our driver soure file (pmc.c) using
FORTE DEVELOPER 6 UPDATE 1 with the following command.
     # cc -Xa -D_KERNEL -c pmc.c
4) The compiler is not able to reach to our source code. It prematurely fails
while compiling the system header files
5) The errors were reported during Preprocessor
compilation in /SYS/*.h header files.

Both itunes and my computer do not recognize my ipod classic, have had this before and reinstalled the device driver when asked to do so. However now it doesn't, how do i get this done?

Neither Itunes nor my computer recognize my Ipod classic. Have had this once before and when asked to reinstall device driver, did that and problem solved. However now I do not get this message, so don't know how to reinstall.

Does any windows service affects the device driver wake up time?

Is it possible for a windows service running on Win 8.1 (64 bit) to delay the wake up time of any device driver?
One possibility could be where the driver has any dependency on any other driver/service.
In this case, I checked the driver's INF file and there is no dependency section.
The driver start up type is service_demand_start and driver type is kernel driver.
Any help on this is greatly appreciated.

Are you asking if a service can impact when the driver is started or when it is woken up after hibernation? For a demand start driver they start when they are needed so depending on the driver yes it could only be started after the service does an
action. You have eliminated the dependency section, but is the driver for actual hardware? If yes then it is highly unlikely the service can impact it. If no, then the service could be the starting it with StartService, or forcing its enumeration
and starting.
If you are talking the hibernation case, no there is impact.

Windows cannot initialize the device driver for this hardware. (Code 37) for Ipod Nano

I have a Ipod Nano for 5 years and Saturday I was updating the latest Itunes and when I connect my Ipod to my PC I got a Code 37 error. I uninstalled the new itunes and put back the old itunes but my Ipod is still having the same error. I did the same thing to unistall the ipod and itunes reboot the PC and installed itunes 10.7 back in and then my Ipod and still have the error. Then last night I tried out my Ipod Shuffle and connect it to my PC and it was installed successfully. Do I have to get a new Ipod if my nano isn't working (but it still plays)?

Is it possible to get the data on the device driver detail property shown below, using scripts?

I have tried to get the data using Win32_PnPSignedDriver but the InstallDate parameter always shows as empty when I try to retrieve it. Also, the Win32_PnPSignedDriver object does not contain all the values that could be seen when you access this window
via Device Manager.

Also it looks like you're attempting scripting using WMI scripting. Perhaps you would want to download
WMI Code Creator v1.0 and read
Utility Spotlight WMI Code Creator.
WMI code creator can create code in VB Script, VB.Net and Visual C# or C#.Net I suppose.
