usb wifi rtl8192cu driver   
Hi everyone !

I'm a newcomer to qnx 6.5.0. I have a USB wifi dongle (Zyxel NWD2205) that
I need to setup an ad-hoc network with. Apparently, the chipset is realtek
rtl8192cu, qnx doesn't have any driver support for this module. Netbsd does
have the driver tho.

http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/dev/usb/?only_with_tag=MAIN
(if_urtwn.c, if_urtwn_data.h, if_urtwnreg.h and if_urtwnvar.h)

I also have the linux drivers from realtek site...

What should I do at this point in time ? Can I simply download the 4 files
from netbsd, create a qnx C project in momentics and make a devnp-urtwn.so
target ? Or am I going about this in the wrong way? Is there a
comprehensive guide that I can refer to about porting netbsd drivers ?
Also, how should I make this driver available for other qnx users like
myself ?

Any help would be much appreciated, thanks.

Re: usb wifi rtl8192cu driver   
Hi all:

I've run into an icky issue with the porting of the netbsd wifi driver. The
code uses async usb tasks which I have absolutely no idea how to implement
in qnx. These tasks are also ordered in a task queue. Can anyone shed any
light on a possible approach? I am currently testing nw_pthread_create in
the attach but getting error 22...

Any advice would be much appreciated, thanks in advance.

Re: usb wifi rtl8192cu driver   
Hi Jim,

Did You succeed with porting this RTL8192CU driver on QNX?
I have similar problem with WiFi USB dongle that runs on RTL8188CU QNX driver i couldn't find anywhere. I've finally 
stuck on your post and i thought Your experience in this matter might be helpfull. On netBSD page You've mentioned there
 is RTL8188CU driver added so this ported driver might work for me as well.

I would be gratefull for any help.

Regards,
Marcin.

Re: usb wifi rtl8192cu driver   
Hi Marcin:

A straight port of the urtwn driver source from NetBSD to QNX doesn't work.
I had to do a raw port using the linux driver instead. Then ran into issues
with device power-on initialization. Unsure if my embedded hardware is
incapable of supporting module or a timing problem with codes. Realtek
vendor support non-existent.

Recommendation: Unless you really need some capability of these new
dongles, otherwise it might be just faster to go with devices that qnx
already supports or opt for a linux distro instead. These new dongles work
great on traditional windows and ubuntu...

fyi: I am no longer working on this problem anymore, my contract has
already lapsed. Hope it helps.

Re: usb wifi rtl8192cu driver   
Hi Jim,

Thank You for quick reply. I think I'll take Your advice. 
Do you know any USB WiFi dongles that QNX supports . 
I'm planning to add WiFi functionality to my Pico ITX SBC and ther's no other way to do it than by USB dongle.

Thanks again,

Regards,
Marcin.

Hi Marcin:

I believe you have to contact qnx support directly, I'm not current with
their list of usb wifi dongle products. Hope it helps. :)
