Entry in /dev for streams device driver

I am building a streams device driver. I have added it to the system using add_drv. I have loaded the module using modload. How do I get an entry into /dev so I can test the driver?

Hi There,
Do you have an entry in /devices?
If so, I had a similar problem and got some help a few weeks ago.
If you look back about 4 pages of messages you'll see mine there.
One suggestion was to make an addition to the devlinks.tab file. I didn't find this worked, but I could well have missed something.
I did find creating a link manually using ln did work and I could access my driver.
Cheers,
Bruce.

Vista is asking for a device driver for ipod vid

I dont have a device driver for it and cant find one so the system wont let me install it. it just leaves a ? in the device manager next to ipod

I am in no way teccy but logged on to this discussion site in desperation this morning after getting same message as you after buying ipod yesterday (twas second ipod and trying to run off one library but long story). I deleted previous software and started again. Tried a few bits from this help site, in particular the article suggested to you earlier but end bit where you uninstall the driver, then kept ipod plugged in and restarted machine; then when vista driver menu started again, asked it to search the whole C: drive for device driver, which it seemed to find somewhere (as I said, not teccy).
End result being that I still get the same message asking for device driver but if I ignore it (ie, click 'next time please' or whatever it says) itunes syncs my new ipod brilliantly (music and photos, not tried vid yet).
Am sure some experts having kittens, but in my ignorance, I have a working ipod and hope Vista and Apple can sort out required tweaks soon and give me auto update. Best of luck.

HT201302 pc with Vista cannot find device driver software for 3GS

Windows Explorer cannot the iPhone. iTunes sees the 3GS, the memory alloted to pictures, but does not show over 1500 pics. iTunes only recognizes pics in files on PC. There are under 50 in the files.
When I plug in the iPhone, it searches for the device driver, but cannot find one.
The iPhone is appearing in Control Panel / Auto Play. Changing this setting makes no difference.
The iPhone also shows up in Control Panel / Device Manager as a Portable Device referred to as a Digital Still Camera, it has a yellow yield icon on it. It says it has the correct driver. Also, below the camera listing is 5 other devices. They are all the same listing of "Microsoft WPD FileSystem Volume Driver", they all have a yellow yield icon on them.
I have deleted all the portable devices and rebooted. They come back, however I have the same problem.
If have tried a number of things, if I recall I saw "Code 10" at one pont. I do not remember the item it was attached to. I will follow-up with more info as I can get. I have had a 3GS for over 2 years. Apple Care tried to help me very diligently on an other Vista machine and had no success. Please Help, someone.

Well its surprising to know that! But even have an ipod shuffle 3rd gen n dint face any problem like that. FYI no cd comes with the ipod jus take ur ipod to an apple exoert n he will solve ur problem .

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..
-Kaushik

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 ??

TS1538 iPhone 5 and Windows 7 device driver not being recognized

I've de-installed in the correct order and re-installed all Apple software for Windows 7 x64 box.
I've manually added paths to the device driver.
I've re-scanned device manager.
I've gone through 4 different kbb articles.
Used 4 different USB ports on the Front Panel of this box.
I've restarted, stopped, started the Apple Mobile Device Service.
I've rebooted 15x, my Alienware R3 laptop works just fine.
I can see the iPhone 5 in iTunes, and this problem has been occurring with my iPhone 4.
Devices and Printers lists the iPhone and Apple Mobile Device USB driver without any conflicts on the exterior.
If you go into properties boom Unvailable. I've turned off every shield in Avast. I only have 1 A/V.
What else can I do?
The rig is a custom built i7 3770s, MSI motherboard, 16gb DDR 3 RAM, USB 3 support etc. I've tried everything... why won't my iPhone get recognized? I seriously do not want to wipe the box for a device driver. Does RDP software create conflicts with USB devices? I have a couple installed.

How do I distribute NI visa device driver?

I am trying to write an installer for a device driver made with NI-Visa Driver wizard. I encountered some problems and I am trying to figure out what is wrong. The installer generator I am using, Setup Factory, mimics the command:
C:\Windows\System32\rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 filename.inf
When I run this command, Device Manger knows the the device is our device because it shows up as a NI-PXI device but it has a yellow exclaimation on it indicating the device has not been configured correctly. I also tried right clicking on the INF file and the same thing occurs.
I was wondering if I was doing something wrong or am missing another command. I noticed that there was an .INI file the driver wizard generated.
The driver installs correctly when I go into device manager right click on the device and update driver as well as at the end of the NI-Visa driver wizard, it prompts to install for me.
Thanks,
Daniel

Hello Daniel,
Unfortunately we do not have documentation to support Setup Factory. Have you tried contacting their support? In your post you say that the driver installs correctly in device manager and with the NI-VISA driver wizard, is this correct? I'm sorry we can't help more!

Old device driver cd, aug 2006

Hi...I am trying to building an installation package that includes the hsdio drivers. I downloaded hsdio driver version 1.72 and installed it. However, when I try to build, it asks for the "Device Driver CD, Aug 2006". I manage to find those disks, but I am missing disk 2. I have newer version but it doesn't work. Can I download the older disks from somewhere?
Thanks.
Solved!

Installing device driver every time I turn on the computer

Every time I turn on my computer or plug in my iPhone 3G, I get the little icon and popup for "Installing Device Driver" and after a couple of minutes it says it installed successfully and then starts installing itself all over again. It's irritating as heck. I'm on Windows Vista and iTunes version 9.1.1.12. I updated Windows and updated iTunes and neither helped. This just started happening within the last week. My computer only has one USB drive and it's the one I've always used. Please help!

It sounds as if you have more than one thing going on here. You say that when you turn on your computer you are getting an icon about installing device driver. Then you say it happens "or plug in my iPhone 3G". These should be two different issues.
Let's isolate the first one. When you turn the computer on, you are getting a device driver popup. This occurs every time you turn on the computer? Are you running it in an administrator mode? What kind of external devices do you have connected to the computer? What USB devices do you have connected, i.e. printer, external drives (not flash drives)?
After that, we can tackle the iPhone issue.

Problem with a DDI Device driver for Solaris 8 and 9 on a Sun-Blade-1500

The problem has to do with dma allocated memory and the little-endian format.
When I copy blocks bigger than 256 bytes to the dma memory, using a uiomove() or bcopy(), the data after the first 32 bytes is swapped around over 8 bytes.
The bcopy from a driver (stack) buffer into the dma virtual memory has the same affect.
So it has to do with the kernel dma allocated memory and the endianess.
When I set the byte order to big-endian inside the ddi_device_acc_attr the data seems to be alright, also with bigger transfer sizes.
My device however needs the little-endian format.
I have the same the same device driver running without any errors on a Sun Blade-150 Solaris 8 for a long time now.
Can somebody please advise me?

OS: Sun Solaris 10 01/06
Hardware: Sun Blade 2500
PCI Memory card.
Problem: When driver moves more then 40 bytes via PIO from a PCI device memory card, the long words are swapped starting at 40 byte transfer size and greater.
device memory description:
static ddi_device_acc_attr_t sdram_access_attr =
DDI_DEVICE_ATTR_V0, /* Boilerplate value */
DDI_STRUCTURE_LE_ACC,
DDI_STRICTORDER_ACC /* Don't reorder accesses */
The user application does a read call, which goes to xxread. xxread calls physio( xxstrategy, bp, dev, B_READ, xxminphys, uio );
In xxstrategy the transfer is done using
ddi_mem_rep_get8(ucb->ucb_sdram_accHndl,
(uint8_t*) kaddr,
(uint8_t*) raddr,
(size_t) bp->b_resid),
(uint_t) DDI_DEV_AUTOINCR );
PCI Device memory is loaded with incrementing address (8bit), 0,1,2... This is confirmed using a PCI Bus Analyzer.
A read of 36 bytes or less returns:
03 02 01 00 07 06 05 04 ...
A read of 40 bytes returns:
07 06 05 04 03 02 01 00 ...
If I peek 1 byte at a time using ddi_get8(ucb->ucb_sdram_accHndl, ...) I get
00 01 02 03 04 05 06 07
Why are the long words swapped starting at 40 byte transfer size and greater?

How to add and configure a usb device driver in SRSS for Sunray?

Dear Sir,
If I want to use a usb device on Sunray 2 (the usb device is plugged into Sunray's usb port), and I have been developed a usb driver on Solaris 10. Can I install the same driver in SRSS host to active the usb device in Sunray? If it can, how do I configure SRSS and where is the location of SRSS drivers? Can I use add_drv similar command to add my driver to SRSS?
The second question is when I plug-in a usb device to Sunray, can I see device information (VID, PID, and so on) in any log file or by any command as "prtconf -v" on Solaris?
Thank you very much.
Best Regards,
Steven

What sort of USB device do you want to use ?
The peripherals chapter in the SRSS admin guide tells you how to use supported USB devices.
http://docs.sun.com/source/819-2384/dev.html
Drivers written for Solaris devices will not work with Sun Ray devices. If you want to write a device driver for Sun Ray, it is recommended you use libusb for a userland driver. See libusb notes on same chapter mentioned above.
There is currently no SRSS utility to list Sun Ray device parameters like prtconf does.
You could write a libusb application to do this, or use the test program described here:
http://libusb.sourceforge.net/doc/examples.html

How to load specific driver for specific device not having PnP-ID?

Hello,
as mentoined in a previous post I'm up to adapt an exisiting PCMCIA-based PC Card driver so that it can be used with a PCMCIA/USB adaptor (by using it's driver's IOCTLs), and already had
some success on it: My driver loads and I can read files (for example, in Windows Explorer) from the card as it did before in "PCMCIA version" (I intend to support both with the same driver, which seems
to work at the moment). As it did before, the driver currently creates a MTD (memory technology device). My main "problem" is how to load the driver.
The situation is a bit complicated, I try to give as much details as possible.
For better understanding
The PCMCIA/USB adaptor's driver usually has following device stack: PCMCIA/SUB adaptors driver -> USB mass storage device (USBSTOR.SYS) -> Diskdrive (DISK.SYS [->PARTMGR.SYS]). For more ease - to see if my driver works in general - I installed my driver
via INF using the PnP ID of the "USB mass storage device", with other words I "replaced" the USB mass storage driver with my own driver.
This is my problem
This means - and that is currently my problem - that may driver gets loaded regardless of what is attached to the PCMCIA/USB adaptor. Usually, when attached to PCMCIA, the PC card has a PnP ID the driver can be assigned to. In my case, I have no PnP ID for
the PC card, and the driver may stop because the attached device is not supported The driver will unload properly, but the device remains with error code (in device manager).
What I want to avoid
I already thought about filter drivers between USBSTOR and the PCMCIA/USB adaptor's driver (#1), or above the USB mass storage device (#2). If I'm correct, that means that I have to handle URB/CBW requests for case #1 or at least SCSI requests for case #2 -
but I'm currently not familiar with filter drivers, URB/CBW and/or SCSI. Porting the driver was quiete frustating until yet and I had to get familiar with a couple of technologies that belongs to the driver's functinaliy itselfs -
I hope you understand that I want to avoid getting familiar with more technologies than required.
I think there must be a way to check the device (PC card) at the PCMCIA/USB adaptor
before my driver will be loaded, as well as removing the deivce completely if the PC card was removed (so that it disappears in device manager). But I'm currently have no idea how to do that. Is it possible to
load my driver along the device/driver stack usually created by the PCMCIA/USB adaptor's driver?
Some answerers likes to refer to WDK documentation and samples. In such case - because of their complexity, it would be nice to get a hint about where to start.
Have much thanks in before for any suggestions!
Regards,
Willi K.

Today's memory cards (like CFC) manage their FTL (flash translation layer) in their firmware. Our PC card is quiete old technology and does not have such firmware, this is why Windows cannot recognize the file system (FAT). For example, a request to offset
0 may be somewhere else on our PC Card.
I followed your suggestion and used the HWID of device that appears "above" the USB mass storage device, and my driver seems to work as it did before - OK, made no difference.
But if my driver does not recognize the card (because it is not present or it is another PCMCIA device -> STATUS_NOT_SUPPORTED or STATUS_NO_MEDIA in driver entry), and the device is shown with exclamation mark in device manager.
Two questions remain:
- How can I ensure that other drivers may attach if my driver does not support the device inserted in the adapter?
- How can I force a "re-check" of my driver if there was no card present when driver was loaded?? -> Note: A disk drive always appears in device manager - regardless if a device is attached to the apator or not

Error installing Driver for audio device in MS-6585 Motherboard

Hi,
I have MS-6585 Max L motherboard. I installed windows 2000 with SP4. When I tried to install driver for the audio device, it always fails with the following error.
An error occurred during the installation of the device.
The data is invalid.
And in the Device status in the properties menu
The drivers for this device are not installed. (Code 28)
I tried to download the latest driver using the "Live Update" and it didn't help. I tried few other options suggested in the web.
The usual cause of this problem in Windows 2000/XP systems is Registry keys that are set as read-only.
From the Start menu, click Run and enter RegEdit to run the Registry Editor. Open the following - Keys => HKey_Local_machine => System => CurrentControlSet => Enum => PCI.
You will see several keys in this form - Ven_xxxx - where xxxx represents a string such as - 1102&Dev_004&Subsys_00011103&Rev_04.
In each of these folders there is another folder that has a long numerical name. Open each of these folders, and look for the DeviceDesc entry that matches the type of hardware that you are trying unsuccessfully to install. Use the right mouse button to click on the Ven_xxxx entry for that device, and click Permissions. If it is set to read-only, then that is the cause of the problem. To rectify it, change it to Allow Full Control.
I'm stuck and I am not sure what else to try. Its not clear to me where the problem is. Is there any log I can look? Any other suggestions please
BTW, It used to work..I had to reinstall windows 2000 and after the clean/format reinstallation it stopped working.
thanks for any help
Suresh

It might be that the drivers are for WinXP. Are you 100% sure they are for 2000? Can you get a copy of XP, it would prabobly solve youre problem.

Udev not loading the right driver for usbtmc device

I have a usb beam profiler and I'm trying to get it to work on arch linux. It works using NI-VISA, so I should be able to communicate with it using usbtmc. However, when I plug it in, it does not show up in /dev.
I think the problem is that udev is not loading the tmc interface driver when I plug it in.
Here's a snippet of the output from lsusb -v:
Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 0
bAlternateSetting 0
bNumEndpoints 4
bInterfaceClass 255 Vendor Specific Class
bInterfaceSubClass 0
bInterfaceProtocol 0
iInterface 0
I believe that bInterface* should look something like:
bInterfaceClass 254 Application Specific Interface
bInterfaceSubClass 3 Test and Measurement
bInterfaceProtocol 1 TMC
iInterface 5 TMC488
Is there a way to force udev to load the right interface? Or is the problem that I'm missing something from my kernel?

Could you post the entire output of lsusb -v for the device?

What device node name are you expecting?
Not sure, but probably /dev/usbtmc0
Is there a chance that it is being instantiated as a HID device? Does /dev/usbhid0 appear?
Nope, don't have a /dev/usbhid0
What does the journal say when the device has been attached?
I'm not sure what you mean, but dmesg says:

and udevadm monitor says:
