Great, we would love to help out.

So the drivers are already written?  If so, do you have pointers to
them?

Or are these two new drivers that you need produced?  If so, are they
variants of the above mentioned drivers and some changes would only need
to be made to them?

The NDA as you have attached does not allow us to create a Linux kernel
driver that would be released under the GPL.  The NDA that we have at:
	http://www.linuxfoundation.org/en/NDA_program
is the one that we have used in the past, as it allows us to properly
create a driver under the legally required license.  Would you need us
to sign that?  If so, you need to sign one of them as well (it's a
3-party NDA), and I can put you in contact with the correct lawyers at
the Linux Foundation to help out with this.

thanks,

Reverse engineering devices is a pain.  I'll not object if anyone wants
to do this, but I'm sure not going to work on it, sorry.

You might want to post this to the developer list instead.

Hi Greg, William,

I believe the 88W8686, 8388 and 8385 are covered by libertas and are
in mainline, drivers/net/wireless/libertas, and work at least when
interfaced via host usb (as in olpc-xo-1). I suspect what William
needs is either additional platform device drivers (ie:
arch/*/mach-*/board-something.c) or libertas interface driver
(libertas/if_*) support for their W003 and W001 products when it is
used with systems other than OMAP3503 (gumstix overo) and i.MX31
(buglabs's device?).

I took a quick look at W003's marketing sheet and it looks like the
host interface can be SDIO, GPIO, or SPI , and btw, there's a
bluetooth module in there as well with more interface capability (USB,
UART, PCM, GPIO, SPI) there too, I assume bluez already supports
W003's bluetooth. W001 says just 802.11b/g and is SDIO, SPI, GPIO. I
think all three, SDIO, GPIO and SPI may now have associated libertas
interface drivers, I see at least if_usb/if_sdio/if_cs in mainline, so
probably all that's needed is platform support.

I'm quite eager to add WiFi/BT to a couple of my currently tethered
devices so I'd be interested in taking this on.

Thanks,
jaya

The better is to copy also the linux-media at vger.kernel.org for DVB
developments. do you know what chips are inside? Maybe there are someone
already working on it.

Hello, thanks for your replies. I'm in touch with Antti Palosaari. He
has ordered the same dongle from eBay and stated at linux-media
mailing list that he wants to write the driver by himself.

I don't know how is it going but I'm gonna contact him and let you
know if he has made some progress.

Great! Antti has lots of experience with those DVB USB dongles.

The main problem with reverse engineering is error detection and 
recovery.

It's pretty easy to determine how a device works under ordinary 
circumstances.  But how does it report error conditions and recover 
from same?  In most cases you can't determine that independently.

I've got a great news -- Antti has released a driver in his linuxtv
tree at http://linuxtv.org/hg/~anttip/ce6230/ about a week ago!

I've done some quick testing and nearly everything seems to work
great. The only issue I've currently found is that the dvbscan gives
"Unable to query frontend status" error, I'm in touch with Antii
hoping to solve this.

Greg,


what is the way of getting drivers out of staging into the maintree?

staging/altpciechdma - Altera PCIe Chaining DMA reference driver.

I have gotten some positive feedback on others now using it:
http://www.alteraforum.com/forum/showpost.php?p=19697&postcount=5

I would like to finish the effort while I get entangled in other projects.

Regards,

If you think it's ready to move into the "real" portion of the tree,
just let me know.  I'll review it and see if it has any problems that I
can see.  If not, I'll submit it for a move and see what happens.

Oh, first, you might want to resolve all of the TODO items in the
driver, those need to be handled at the least, right?
