PROBLEM: p54usb doesn't work with my Philips CPWUA054 usb adapter

Hi,

I followed the guidelines for a bug report.
If there is anything else needed, I'll be happy to do all the testing needed.

[1.] One line summary of the problem:
p54usb driver crashes on trying to associate with an ap with the CPWUA054 usb adapter

[2.] Full description of the problem/report:
What works:
modprobe p54usb
dmesg (displays my adapter correctly)
ifconfig up wlan0
dmesg (using the right firmware 2.5.6.0)

but trying to associate to my accesspoint (using wpa_supplicant) causes a hard-lock up (keyboard leds blinking). Before locking up it spams loads of 'RX: unknown frame received phy1' messages on kmsg/dmesg.

Note that my adapter isn't in the vendor:model id list of the p54 driver, my patch submitted for that is prob. lost somewhere. But I'm using islsm with my usb adapters for >1.5 years with no problems.
lsusb lists my device's model/vendor id
Bus 001 Device 002: ID 083a:5501 Accton Technology Corp.

I also tried the wireless-2.6 kernel some months again with the same issue, though I had some kernel option on that allowed me to do a traceback to the failed function, *rx*() i believe (in p54 itself). I'm not really familiar with kernel debugging but i'll try to give you the full trace in a couple of days, have to figure out how to do it again.
If there is anything else that is useful, I'll be happy to provide it.

[3.] Keywords (i.e., modules, networking, kernel):
wireless, p54 driver

[4.] Kernel version (from /proc/version):
If some fields are empty or look unusual you may have an old version. Compare to the current minimal requirements in Documentation/Changes.

Please switch to a VT (e.g. VT 1, usually by pressing ctrl-alt-f1) and associate by hand (e.g. iwconfig wlan0 essid "your ssid") and take a picture of the oops that comes out.

Sorry for the late reply, i just thought i install kernel 2.6.25 r4 and try again.

It is somewhat better and worse, when modprobing p54usb i got a small hang/hickup accompanied with the following error in dmesg ehci_hcd 0000:00:02.2: HC died; cleaning up

afterwards the kernel fails (refuses ?) to detect the device again. so I no longer get a kernel oops but even modprobbing doesnt work anymore. see attachment for full dmesg. any ideas, testing i an do now ?

kind regards,
Ivo Couckuyt

usb 1-5: USB disconnect, address 3
usbcore: registered new interface driver prism54usb

Sorry, no idea. Christian?

Not yet... but card is on the way, so maybe in the future. :)

I googled for "HC died; cleaning up" and yes, there "are" other people with the same issue... But noone had a solutions other than use ndiswrapper.

So, i took a look at the driver... it ships with a really old firmware 2.4.6.0 So, I know that there are atleast some (mini)PCI Cards that have big problems with anything newer than 2.4.x.y, maybe there are broken USB-Parts too...

Ivo, can you please try the older firmware? You can find a copy @
(http://daemonizer.de/prism54/prism54-fw/ scroll down to USB).

If this doesn't work? could you please about ndiswrapper?

Regards,
Christian

i tried the following firmwares:
2.4.4.0.arm 2.4.6.0.arm
2.5.11.0.arm 2.5.6.0.arm 2.5.2.0.arm 2.7.0.0.arm
All give the same dmesg output, (HC died; cleaning up)
except 2.5.8.0.arm which gives something else, probably not worth much, but nevertheless see attachment

In the very beginning I used ndiswrapper without any problem (still works now), but at the moment i'm using the old islsm driver together
with kernel 2.6.9 and firmware 2.5.6.0 (only one that works), which doesn't seem to be on the site you mentioned
md5sum:
6ff238179cf9618aac2b5d7a34e41450 2.5.6.0.arm (is included for what it is worth)
So i've been stuck at kernel 2.6.9 for some time now as islsm doesn't compile with newer kernels :-) p54usb should be a relatively straight port from islsm yes ? except for the control rate algorithm and some cleaning up i guess.

ps: thanks for the effort.
ps2: firmware 2.5.7.0 isn't on site too: 09f9da7ea757173c9de1a0322a1f9782 2.7.0.0.arm

kind regards,

This is the Internet, nothing is ever lost... :-)

FWIW, your old patch was against the prism54usb driver. I retargeted against p54usb and just posted it to this list. I'll send it upstream with the next round of fixes.

Great, thanks

k, i configured my ap as plain text and turned off xorg.
In the first console I did:
ifconfig wlan0 up
iwconfig wlan0 essid ilm
dmesg shows several of this lines... which is normal scanning i believe:
...
HW CONFIG: channel=8 freq=2447 phymode=2
HW CONFIG: channel=9 freq=2452 phymode=2
HW CONFIG: channel=10 freq=2457 phymode=2
HW CONFIG: channel=11 freq=2462 phymode=2
HW CONFIG: channel=1 freq=2412 phymode=2
...
iwconfig -> Not-associated

wlan0 IEEE 802.11g ESSID:"ilm"
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated Tx-Power=27 dBm
Retry min limit:7 RTS thr:off Fragment thr=2346 B
Encryption key:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

but nothing, so i do
iwlist wlan0 scanning
which 99.99% of the time returns nothing, and very occasional one accesspoint that isn't mine.

configuring wpa_supplicant for plain text and starting it in the foreground gives me:
ioctl[SIOCSIWAUTH]: Operation not supported
WEXT auth param 4 value 0x0 - ioctl[SIOCSIWAUTH]: Operation not supported WEXT auth param 5 value 0x1 - ioctl[SIOCGIFADDR]: Cannot assign requested address ioctl[SIOCGIWSCAN]: Resource temporarily unavailable ioctl[SIOCGIFADDR]: Cannot assign requested address
ioctl[SIOCGIWSCAN]: Resource temporarily unavailable ioctl[SIOCGIFADDR]: Cannot assign requested address
ioctl[SIOCGIWSCAN]: Resource temporarily unavailable ioctl[SIOCGIFADDR]: Cannot assign requested address
ioctl[SIOCGIFADDR]: Cannot assign requested address
ioctl[SIOCGIFADDR]: Cannot assign requested address
ioctl[SIOCGIFADDR]: Cannot assign requested address
ioctl[SIOCGIFADDR]: Cannot assign requested address
ioctl[SIOCGIFADDR]: Cannot assign requested address

Which i think isn't really relevant to the problem, in any case wpa_supplicant doesnt work. The strange thing is i don't get any oops anymore, that only happeneded with wpa_supplicant AND wpa enabled

Using the good old islsm driver i can configure it all manually without problems:
ifconfig eth1 up
iwlist eth1 scanning -> returns about 5 ap, including mine
iwconfig eth1 essid ilm
iwconfig -> shows associated
dhcpcd eth1 -> in business

so apparantly the p54usb/cpwua054 combination doesn't find the ap in the first place.
I vaguely remember some thread on the islsm mailing list about those unknown frame messages that may be related to the empty scan results, to be exact:
...
phy0: unknown frame RXed (0x20)
phy0: unknown frame RXed (0x30)
phy0: unknown frame RXed (0x30)
phy0: unknown frame RXed (0x20)
phy0: unknown frame RXed (0x20)
phy0: unknown frame RXed (0x20)
...

Next step is probably enabling debug in the p54usb driver i think, if possible. Any suggestions for tests i can do ?
