Please don't send reports like this to me privately, there's no point.
I won't be able to fix individual drivers that I don't know. Make a
public report, and try to figure out who is in charge of that driver.

I've added the most active rtl8192 authors/people to the Cc, along
with linux-wireless. Hopefully that includes somebody who can help.

Can you try a kernel.org kernel release, and not a Ubuntu kernel?  If
not, you're going to have to report this to the Ubuntu developers, not
much we can do here.

If so, can you see if the in-kernel version of the driver has ever
worked for your system?  Try an older release, like 2.6.34 or 2.6.32 and
see if that works.

thanks,

Could you send patches updating the in-kernel version of this driver to
your latest version?  That would help everyone out in the end.

I have a copy of the driver that Realtek calls the r8712 for the RTL8192 USB
devices. All of the dead code and the unneeded configuration sections have been
removed. It will be submitted to staging as soon as Realtek signs off on the
copyright info. For some reason, it has taken them several weeks and I still
have no answer. This new driver is stable - the connection stays up for days. I
expect that it will replace the current one in staging.

Wonderful, that's great news.

Jerry, any word on getting the copyright sign off moved along?

Re: Hi,Linus Torvalds. There's a problem in r8192u driver in Linux new kernel.

Gauss,

What is the USB ID for your device. The reason I'm asking is that Florian and I
have been working on porting a new vendor driver for the 8192u devices. The plan
is to submit this to staging. At the moment, it has been tested with big- and
little-endian, and 32- and 64-bit systems. Everything is working except for
suspend and resume.

If your device is one of those that Realtek says works with this driver, and you
are willing to build a kernel from scratch, I will send you the URL for a git
tree containing it. That will have to be done privately as I'm still waiting for
Realtek to approve the copyright statements in the code. It is GPL'ed, so I do
not expect any difficulties, but their lawyers have to sign off.

Larry,

I'd be interested in trying your driver version. I don't think it's in
the main tree yet because the change I see for the rtl8192su is on
2010-08-11, but there is a bunch of stuff from Florian from July.

I'm trying to get the rtl8188su chip to work, and more specifically to
get it to work without depending on PCI on arm.

thanks,
Paul

Yeah, that works! This is great because most of the "mini" wifi cards
use the rtl8188su. This is on an Atmel at91sam9g20 arm processor, it
only has 12Mbps USB. I haven't tested wpa yet.

thanks,
Paul
