Re: r8712u staging in kernel 3.2.9

[alupu@verizon.net]

 Hi Larry,

I ran a few more tests around the subject thread.
Brought up my machine on the Knoppix-6.7.1 DVD, (his latest):

uname -a
Linux Microknoppix 3.0.4 #12 SMP PREEMPT Thu Sep 8 05:27:05 CEST 2011
 i686 GNU/Linux

iwconfig --version
iwconfig Wireless-Tools version 30
 Compatible with Wireless Extension v11 to v22.

 Kernel Currently compiled with Wireless Extension v22.

Please note the same weird version, 30.
There must be a thriving black market for wireless-tools in Germany :)

Whatever driver Knoppix uses, it is in the kernel
(i.e., not as a module) and BTW, 'iwconfig wlan0 essid ...'
 doesn't work either.

lsusb --version
lsusb (usbutils) 0.87

Two odd things:
1. Bus 002 Device 003:
 ID 0bda:8172 Realtek Semiconductor Corp. RTL8191S WLAN Adapter
 
Please note "RTL8191S" above.

2. ls -og /lib/firmware/rtlwifi
 -rw-r--r-- 1 122328 Jan 4 2011 rtl8712u.bin

As opposed to things on my subject machine (3.2.9):
lsusb --version
lsusb (usbutils) 0.73

1. Bus 002 Device 003: ID 0bda:8172 Realtek Semiconductor Corp.
Note: the missing "RTL8191S" could very well be caused by
 my using a lower lsusb version.

2. ls -og /lib/firmware/rtlwifi
 -rw-r--r-- 1 129304 2012-03-04 15:42 rtl8712u.bin
------

The 'menuconfig' on my version, 3.2.9, has only these choices for
RTL staging devices:
 8187SE
 8192U
 8192E
 8712 (8192SU)

No trace of an RTL8191S possibility.

Maybe you can make more heads (or even tails) of it.

Regards,

PS.  Just to prevent any uncalled-for suspicions, this Rosewill device
works smoothly and perfectly on Win XP (very same machine, different
partition) and Win 7.  Surprise, surprise.
