OK, I have read not to post here because it is first forum on list , but...
I would like to talk to someone who is INTERESTED and knows something about USB.
I am not looking for code samples etc.
I have a basic USB code running on SAM3x8e / AKA Arduino Due.
Based my design on code posted here, but as it is always my case - the author of the very long article is no longer on this forum.
I have basic understanding how USB works on ATmel ARM processor.
I have test connected several USB devices and NONE of them gives SAME results.
I can reliably and repeatedly connect and reset single USB device on / to USB port.
One of the devices is USB WEB CAM and it actually sends IN packet but it is missing header.
So that is my basic question where I really could use some help from somebody knowledgeable about USB innards.
How to verify contents of packet asking for data and than verify the actual data received.
Concretely - which descriptor is the "source " sender - I have over 40 of them enumerated - including UVC descriptors.
I am sort of speak "over my head" and would appreciate if you could contribute to solution with your personal knowledge.
I am not seeking references to Google.
Been there , done that.
Thanks for your time
Vaclav
PS No "check out Arduino.cc" I am not welcomed there.

I believe Hardware & Devices Discussion Boards[^] is the closest fit for what you are looking for.
There are only 10 types of people in the world, those who understand binary and those who don't.

Thanks for reply.
I have not had much luck posting there either.
Cheers

That's because this is primarily a site for Software developers. The hardware guys don't come here too often.

If it is windows kernel then OSR online is the only forum that exists.
They often go into hardwarte discussions, so you will be OK posting there.

Just posted a question of code C but I can't see the code can others see the code because if they can't see the code how can they answer the question  .... there anyway to know how to ask a question

Question posting has really a simple and user-friendly UI, go through the below URL and you can post a question
Question Posting[^]
If you have to put some code snippet then you can do it using PRE tags and appropriate language selection.

The only reason people get lost in thought is because it's unfamiliar territory.

hi and thanks for solution!

please use tha name of field instead of these.
when use parameter s with nams '@val1' or '@val2' and ......and use stored procedur sqldatasource insert null value to database.although ,when i use another procedur whit parameters that have same name with field it work correctly.

Since today morning, I noticed a right aligned line of texts in the code block (wrapped with pre tag pairs) which says "Colourised in 58ms". Can any one guide what it actually means?
Is this something similar to Visual Studio feature which indicates like "12345ms elapsed"?
Can anyone educate me?
Thanks in advance ! 
Note: I am not sure if this is the right category of forum to ask the question. Suggestion on this would be helpful too.

It might be useful to know what application you noticed this in - presumably VS

No it is here on CodeProject in forum messages:
int i = 0;
while (true)
{
++i;
if (i > 1000)
break;
}
|
|
|
|
|
Yes.. True. I noticed this in codeproject.

It's a site feature. If you surround a block in pre tags in the editor, it tells you how long it took to colour the block.
For instance, this section of
formatting told me that it
took approximately 3 ms
to format successfully.

I suspect it's an artefact of the formatter that CP is using. This type of question would normally be asked in the Lounge but is also suitable for the Site Bugs and Suggestions forum because you are asking about site behaviour and, as that's where the CP team hang out, that's where they should see the question.

No, it's just Bob showing what a smart guy he is. Or is it the hamsters taking over?

I think it's Bob only. The smartest guy.

How to delete a thread in code project.. please help
|
|
|
|
|
If you wrote it - and it has no answers - then you can delete it yourself just by opening it and clicking on the "Delete" option at the bottom.
If it's been answered, then the Delete option will not be available, and you need a Protector or above to remove it.
Which one did you want to get rid of?
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

I had to laugh...
referencing Cybercrime Survival Guide here on Code Project...
https://www.codeproject.com/ResearchLibrary/235/Cybercrime-Survival-Guide/?lctid=4[^]
In the battle of obtaining your information, ignorance is their greatest weapon,
So before getting the document they want us to read we have to give then our information????? WTF???
And an optional password? For what?
Is this advertising, or a freebie? Why can't they give it away for free without asking us for our information?
I'm not ignorant so I won't be subscribing to this "wanting my information".
Thoughts?
