Stealth Wimax driver drvxi314.ko?

[SteveRiley]

Perhaps you might need to find a WiMAX interface that's already been tested in *buntu. I don't have any experience with such things, so I can't offer suggestions.

BTW, both insmod and modprobe are used to load modules into the kernel. If one works, the other will too. Check the man pages for more details.

The output of locate shows the drxvi314.ko module in /lib/modules/3.8.0-26-generic/. But your ls command in that subdirectory does not. This tells me that the file does not exist, and your locate database is out-of-date.

. . .

I suspected that. It must be a leftover from some failed attempts to compile the driver to an earlier kernel.

What exactly does this drxvi314 module do, and how is it related to bcm_wimax?

drxvi314.ko is the Linux driver based on the original Windows driver drxvi314.ko for wimax broadband. Bcm_wimax is the Linux replacement of drxvi314.ko. The latter is supposed to take the place of drxvi314.ko and activate and operate the wimax modem. As you can see, it does not do so in my case. Other user report that it does work with Kubuntu 12.04. (It did not for me).

Bcm_wimax together with two firmware files is supposed to make the modem work. In my case it works for 3G and I now can power up the 4G modem. But bcm_wimax does not recognize the modem. Therefore nothing happens and I am still stuck.

By the way, the modem is the Franklin U600 modem. It is a dual modem, 3G and 4G Wimax.

As far as bcm-wimax is concerned it does show with lsmod. I also can modprobe it. Insmod does not work, I believe to remember.
But, as I said, the driver appears to be doing nothing. It does not recognize the modem contrary to what others are reporting.

Stealth Wimax driver drxvi314.ko

Sorry for the delay. I could not find my own post for a while - thanks to the unusual title.

Attached is the result of strace modprobe ... as suggested:
SORRY, I attempted to upload the resulting file for your info but got a dressing down for 'malicious behavior', etc.

Anyway, to make a long result list short:
Driver/file not found or does not exist.

Here it is shown:

peter@pjj:~$ locate drxvi314.ko
/lib/modules/3.8.0-19-generic/drxvi314.ko
/lib/modules/3.8.0-26-generic/drxvi314.ko
/usr/src/USB_350/Source/Driver/Network/OSAL/Linux/usb/drxvi314.ko

in detail:

/lib/modules/3.8.0-26-generic$ ls -a -l
-rw-r--r--  1 root root 290404 Jun 17 15:19 bcm_wimax.ko

Exceprt from strace modprobe ...:

open("/sys/module/drvxi314/initstate", O_RDONLY|O_LARGEFILE|O_CLOEXEC) = -1 ENOENT (No such file or directory)
stat64("/sys/module/drvxi314", 0xbfd059ac) = -1 ENOENT (No such file or directory)
write(2, "FATAL: Module drvxi314 not found"..., 34FATAL: Module drvxi314 not found.
) = 34
exit_group(1)

Anything interesting in

sudo strace modprobe drvxi314

My attempts to install the module drvxi314.ko to 13.04 have resulted in a file by this name. However, modprobe and insmod declare emphatically that such a file/driver does not exist.
I am looking at it in /lib/modules!
It has the correct date of creation and a size that can be reasonably expected.
But it cannot be installed.
'insmod' gives error 'file does not exist'. Modprobe does essentially the same.
Why?
Does anyone know?

The Linux driver bcm_wimax also exists (it comes with the kernel). It even responds to modprobe by showing up for 'lsmod'
But again, it does not do anything. Nothing is attached to it and the modem does not light up.

Since other users are using bcm_wimax to run a modem, it can not be the actual bcm_wimax file.
But what else?

drxvi314 works fine with XP.
