Is there a reference document(example, code) for developing usb mini port driver?

Hi:
I studied Bus\USB document of WDK. This document forces on developing USB device driver.
And there are some IOCTL Interfaces of usb bus driver exposed to usb device, like IOCTL_INTERNAL_USB_SUBMIT_URB.
But those IOCTL Interfaces seem to belong to USB hub driver(usbhub.sys).
My job is to developing a usb mini port driver, like usbehci.sys. That can work with usbport.sys.
So I should know the communication interfaces(IOCTL...etc) between them and implement these interfaces.
Is there a reference document(example, code) for developing usb mini port driver ?

No there is no reference documents for this, Microsoft stated from the beginning that they own that layer. You really don't want to go there.

Home fix for broken usb mini port? (Zen Xtra 40g

I bought my zen xtra from a friend about a month ago, and it was in perfect condition. Recently it wasn't being recognized by my computer, and then the usb port on the player slipped into the casing. (I think it wasn't recognized by the comp because the port was starting to slip, which wasn't providing a solid connection) Anyway, I was wondering if I could buy a player from e-bay, one of the ones with a broken hard dri've or something, and replace the peice with the usb port? Is this something someone with a bit of knowledge of tinkering with electronics could do? I haven't opened the case to look yet, I wanted your opinion first.. I was also wondering, if I do buy the parts from e-bay.. can I use the parts from a 30 gig player or does it have to be the 40 gig? There are tons of parts for 30 gig players on e-bay, and not many for the 40's.... any help would be appreciated.

Yep, you can certainly do this (although eBay's always a risk). The best thing to do would be a swap of the hard disks. Rudi Cheow's guide has some detail about dismantling a Zen, but this is for an earlier player. The Xtra is a little different, but not a million miles away.

Is there example code for using Ni488 and PCI-GPIB card in non controller mode?

Is there example code for using Ni488 and PCI-GPIB card in non controller mode?

cymrieg,
Your code looks good to me. What is the problem? What happens when it fails? What is the IBSTA value on the controller, and at what point in the code does it stop? What is the IBSTA value on the slave, and at what point does it stop?
One thing is that you might not want to call IBCLR() in a loop on the device. At the beginning of the program is fine...This will send a clear command to the device and will clear out any LACS and TACS bits that might be set. Also your IBDEV call shouldn't be in a loop.
Hope this helps, but let me know if you need more information.

Hi All,
I want to know some examples for guidance in writing the Abap Routine at Data Target of Info Package for Deleting the Request from Info Cube after Update.
In the Data Targets of Info Package for Info Cubes we can delete the previous request based on the Conditions, exceptions and also based on the Abap Routine. I just want to know how do we write the Routine.
This option is adjacent to the Maintain to Data Target in Data Targets of Info Package and will available for Info cube only.

kevjava wrote: 2. Line numbering, and/or a line counter so you can see how much scrolling you're going to be imposing on the forum readers.
Good idea, and since the line count is only a handful of lines of code to implement, I took that option. See the [line count|http://pscode.org/stbc/help.html#linecount] section of the (new) [STBC Help|http://pscode.org/stbc/help.html] page for more details. (Insert plaintiff whining about the arbitrary limits set - here).
I considered adding line length checking, but the [Text Width Checker|http://pscode.org/twc/] ('sold separately') already has that covered, and I would prefer to keep this tool more specific to compilation, which leads me to..
kevjava wrote: 1. A button to run the code, to see that it demonstrates the problem that you wish for the forum to solve...
Interesting idea, but I think that is better suited to a more full blown (but still relatively simple) GUId compiler. I am not fully decided that running a class is unsuited to STBC, but I am more likely to implement a clickable list of compilation errors, than a 'run' button.
On the other hand I am thinking the clickable error list is also better suited to an altogether more abled compiler, so don't hold your breath to see either in the STBC.
You might note I have not bothered to update the screenshots to show the line count label. That is because I am still considering error lists and running code, and open to further suggestion (not because I am just slack!). If the screenshots update to include the line count but nothing else, take that as a sign. ;-)
Thanks for your ideas. The line count alone is worth a few Dukes.

How to modify the ni 9237 example code for 3 9237 modules

I am wanting to modify the ni 9237 example vi(for only one module) for three 9237 modules.
I have tried several approaches but it does not seem to work well.
Your help is greatly appreciated.

There are my files. Thanks in anticipation. This code is modified for only 2 ni 9237 modules. I bet it would be a logical extention upon making it work for 2 modules.
