No, not submission. The fact is that no one bothered to review the code. It was simply flat out NAK-ed it in just four minutes, fronting one of their co-workers with the defunct driver already in.

It would've been a different story if Greg, Alan and you and anyone else willing, had provided a technical review, and /then/ reject it--the rejection reason would've been clearer to everyone, than taking all this thread to get to.

Greg didn't review it and rejected it 4 minutes after posting. Alan didn't review it and after I posted the 18 technical reasons (my 2nd post in this thread replying to Greg's) said this:
> Your driver may be the best on the planet - who knows - 
Obviously he didn't review it.
You, after I posted the driver and the 18 technical reasons, said this:

and

These are from this very thread.

I've already stated that there had never been an agenda about uasp.c and Linux. The uasp.c driver was written over most of a Saturday (when I had time and uas.c showed itself to be defunct).  Since uasp.c is a working driver and correctly implemented in terms of UAS, USB, SCSI, the kernel and it's layers, I thought it would be *helpful* and *useful* to people--that's all.

The driver was rejected flat out only after 4 minutes after submission claiming that there is a driver in the kernel that "does the exact same thing".  I then provided 18 technical reasons as to why uas.c does NOT in fact do the exact same thing to which Greg responded with:

> But again, this driver is not acceptable as-is, sorry.

Why would he have to apologize? Anyway, to which you responded with not knowing which driver is good.

When people read "the community" responses in these mailing lists, they think "Wow what a benevolent bunch of people" and "look, they just wanna help". But what this mailing list doesn't show is that this is a very close knit of people who work for the same company (or two) and who go to Linux conferences religiously and are very close buddies. Obviously uasp.c didn't stand a chance _and_ was rejected in just 4 minutes, without a technical review. As you can see in this thread the three of you kept fronting the uas.c driver despite the 18 technical reasons I posted and the fact that it's badly written, and needs to be replaced with something that works, as people will find out when UAS devices make it to market. It's all in the beginning of this thread, start reading here:
http://marc.info/?t=129165521000011&r=2&w=2

So after such a blatant refusal to even give a technical review of the driver, it had me thinking: why would that be?

If you reviewed it, then why did you write that you had no idea if the driver were good or not? Here is what you wrote in this very thread:

> If, in fact, Luben's driver is somehow "better", ...
and

Your full message can be found here: http://marc.info/?l=linux-kernel&m=129186163519728&w=2.

But now you say that you had reviewed it!? Now you say you found the driver "interesting" but "no compelling reason to prefer it over the old". How about that it works? How about the 18 technical reasons I posted *before* you posted your response quoted above (which reasons you had read)?  You didn't address any of them.

> It was only until, after your submission was refused,

It was flat out refused only 4 minutes after I submitted it.

The reason I posted the 18 technical reasons, is because Greg claimed that uas.c "does the exact same thing". His response is here: http://marc.info/?l=linux-usb&m=129165544600441&w=2, he posted this only 4 minutes after I posted the driver. I therefore decided to clarify that uas.c does NOT in fact do the "exact same thing", and backed that up with the 18 technical points.

What does this actually mean? I just posted my uasp.c driver in this very thread and it got rejected 4 minutes afterwards without technical review. When I followed up with a technical review you say "your inability to work within the standards of behavior of the community".

Does providing no technical review and flat out rejecting a driver fall into your "inability to work within the standards of behavior of the community" definition?

1. The whole thing should be ripped out. Any good work would change 100% of the driver as uasp.c shows (essentially getting a new driver in).
2. I did make that "statement" in the 18 technical reasons of why uasp.c was better than uas.c, other than "it works" of course.

I did. In the 18 technical reasons I listed in this very thread. Here is the link: http://marc.info/?l=linux-kernel&m=129185378712222&w=2

And those are? I think you're priming up here what people should think.

I said that in the 18 technical reasons I listed, link above.  The existing driver is badly written, the infrastructure is just off.

It's simple, rip out uas.c and put in uasp.c and give people something working and let everyone contribute to something with good foundation.

Actually, it's very easy to deal with me. When people come to me, I say "What can I do to help you?" and then I provide them a solution and always go the extra mile, and give them something constructive they can use, and I say, "here it is, and I did this extra thing and let me know what else I can do for you."  Most of the time I don't wait for people to come to ask me, but proactively contribute to the end goal, surprising people with "it's already done" when they ask for it.
