Any solve to the SR9700 problem

[123nbom]

So I have this SR9700, it does not support Linux.
After installing Linux, I found that this device is not compatible. I tried various methods, such as running it in bottles and entering commands in the terminal, but none of them worked.
The problem is that Linux only recognizes this device as a CD drive. I don't want that-I just want the device to work with Linux.
Could you help me with this?
I contacted the company that manufactured this device, but they didn't provide a helpful response. They simply mentioned that the driver was added in Linux 3.12. I messaged them again about it; they informed me that the device is too old and only support windows, hence it does not support the Linux apps.

Question: how to install this kernel code?

[Doug S]

That kernel code is included in the kernel by default. The driver is a module, which is normal. The crc stuff is built in.

doug@s19:~/kernel/linux$ grep CONFIG_USB_NET_SR9700 /boot/config-6.8.0-35-generic
CONFIG_USB_NET_SR9700=m
doug@s19:~/kernel/linux$ grep CONFIG_CRC32= /boot/config-6.8.0-35-generic
CONFIG_CRC32=y

I wonder if the module is getting loaded when required. You could check after trying your device and/or force load it:

doug@s19:~/kernel/linux$ lsmod | grep sr97
doug@s19:~/kernel/linux$ sudo modprobe sr9700
[sudo] password for doug:
doug@s19:~/kernel/linux$ lsmod | grep sr97
sr9700                 20480  0
usbnet                 61440  1 sr9700
mii                    20480  2 sr9700,usbnet

Must i try the second code in terminal or the first one? I've unplug the device and plug it again-But it didnt work (Ubuntu detected it as a CD drive). What do i do now?
1-EDIT: is there a way to load the driver from the kernel itself? Maybe install the driver from the kernel.

[Doug S]

is there a way to load the driver from the kernel itself?

Yes, you can force load the driver module via the command I posted before:

doug@s19:~/kernel/linux$ sudo modprobe sr9700

And then you can check that it is a loaded module via the subsequent command I posted earlier:

doug@s19:~/kernel/linux$ lsmod | grep sr97
sr9700                 20480  0
usbnet                 61440  1 sr9700
mii                    20480  2 sr9700,usbnet

The device didnt work

Can anyone make the driver for me.
I have the .c file, its done - its need just need the other things that i dont know
Ubuntu 20.04.4 LTS
https://git.kernel.org/pub/scm/linux...00.c?h=v6.10.6

[Doug S]

As explained in my previous posts on this thread, you have the driver. As far as I know, there is nothing for us to do to help you further.

What kernel version are you using now?

EDIT 3: If I understand correctly, you think you need the latest version of the driver that include this commit from July 25th and that has been back-ported to kernel 6.10.6:

    net: usb: sr9700: fix uninitialized variable use in sr_mdio_read

    It could lead to error happen because the variable res is not updated if
    the call to sr_share_read_word returns an error. In this particular case
    error code was returned and res stayed uninitialized. Same issue also
    applies to sr_read_reg.

    This can be avoided by checking the return value of sr_share_read_word
    and sr_read_reg, and propagating the error if the read operation failed.

    Found by code review.

I will be using Ubuntu 20.04.4 LTS based on Linux kernel versions 5.4 and 5.8. Will the updated drivers make my device work as intended? I think that i need the latest driver to ensure my device functions properly. Initially, my priority was to simply make the device work, regardless of whether it functions perfectly or not. At the very least, I want it to work.
Is there a way to update or install the driver online? For example, can I use a command like 'sudo update sr9700' to do this?

No.
