Re: Delivery Status Notification (Failure)

[miloofr]

Hi,
I would want to know what is the current state of the 8191su wireless
driver. I have a wifi USB stick from EDIMAX, the 7811Un model, which is
supposed to have a 8192su chip inside.
It is not recognized neither from latest Ubuntu 10.10 nor openSUSE
11.3 . However I have been able to make it work by compiling the
drivers proposed on the EDIMAX website, but this is only available for
32 bits systems/kernels.
I saw that there were some discussion 2 months ago about this port
from 32 to 64 bits, what is the current state today?

What are the USB IDs for this device as shown by lsusb?

If the numbers are 0x7392:0x7611, 0x7392:0x7612, or 0x7392:0x7622, the device is
supported by the r8712u driver in staging and is present in mainline kernel
2.6.37-rc1. I can assure you that the driver works for both 32- and 64-bit systems.

Re: Question about Edimax 7811Un

[miloofr]

The device as shown in lsusb is:
0x7392:0x7811

The vendor id seems to be different as those recognized by the  r8712u
driver. How could I try the driver to confirm that the 7811 device
works with this driver?

Please use the "Reply-to-all" when you respond to an email. I want to keep the
wireless mailing list informed about what we are doing.

Driver r8712u does not appear to work with your device. I could not get the
Linux driver source for the 7811 to download from the Edimax site, but I found
it on the Realtek site as RTL8192CU_v2.0.1126.zip. There is a tarball inside
that zip file with the Linux driver. It does not compile under 2.6.37-rc1. From
the warnings, I can see that it needs work to get it to run on a 64-bit system,
but it is likely to work in the 32-bit version.

Realtek is sending me some sample devices. If one of these nano USB devices is
included, I will convert the driver to 64 bits and send the modifications back
to Realtek. If/when that happens, I'll let you know.

Larry

Re: Question about Edimax 7811Un

[miloofr]

Thank you.

In fact I successfully compiled this driver (latest 1126 version) with
a 2.6.35 kernel from ubuntu 10.10 . It seems to work ok, except some
freezing sometimes while booting with the stick installed on the PC.
It also compiles with the same kernel on a 64 bits system, with a lot
of errors, but does not work at all (freezes immediately). It is
precised in the doc of the realtek linux driver that this is a 32 bits
driver.
Can you warn if the usb stick is in the samples sent from Realtek?
If necessary, I can test your 64 bits converted driver on my system
and give you the results in order to fix it.

Eric

PS: sorry for the reply-to-all forgetting. I realized that one minute
after and resent my email to the ML also ;).

Eric,

Attached is a patch that compiles cleanly on a 64-bit system. I have not tested
it as I have no device.

There are two kinds of differences between 32- and 64-bit systems. The first is
the size of a pointer, which becomes important whenever there is a need to keep
one as an integer. The original driver stores them into a u32 or a uint, which
is too short. These problems are solved by storing such values in variables of
__kernel_size_t. The second problem occurs for the communication buffers. There
are 4 quantities: head, data, tail and end. For both 32- and 64-bit systems,
head and data are pointers. With 32 bits, so are tail and end, but for 64 bits,
tail and end are uint.

I got all the ones the compiler complained about.

Larry

Re: Question about Edimax 7811Un

[miloofr]

Thank you Larry. I successfully compiled the patched driver on a 64
bits system without any error. The driver loads, no freeze when
inserting the stick, however, there are a lot of timeout errors, as
shown below (the drivers seems to unload itself). That's why I guess a
"lshw -C network" does not show the wireless usb network.
