Module Troubleshooting with x86_64 Kali Linux

[mahatah]

First, I want to say thanks for making this driver. Although I may be struggling to get it to work, I appreciate your efforts to provide a working Linux module for the community.

With that, the issue I seem to be having is with the kernel module. Compilation goes fine with no errors, but the module doesn't load when using the nano device. I've ran modinfo on the 8822bu module and will output the information below. You'll notice that the "parms" for the module appear incorrect. At present, I'm not sure how to fix this and was hoping you may have some inclination as where to look.

Output of "uname -a": Linux IT 4.9.0-kali4-amd64 #1 SMP Debian 4.9.25-1kali1 (2017-05-04) x86_64 GNU/Linux

What is the result of lsusb

[mahatah]

Doing just lsusb is the following: Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 002 Device 004: ID 0e0f:0002 VMware, Inc.

With that said, if doing lsusb -vv then the relevant USB information for the nano is as follows: Bus 002 Device 006: ID 0b05:184c ASUSTek Computer, Inc.

[brandon-bailey]

Please check the latest commit, I just added your device descriptor.

[mahatah]

Thank you much for the help. Removed the old driver, re-downloaded the repo, recompiled and reinstalled with make and make install. Restarted, made sure the 8822bu driver was loaded with modprobe and confirmed that it was with "cat /proc/modules/ | grep 8822". Plugged in the Nano and... nothing. :-(

I'm downloading a fresh copy of the OS and will try to install the kernel module on that to verify whether some personal configuration is to blame or not. I'll post the results after that's complete.

[mahatah]

After doing as mentioned in my previous post, I can confirm that there is no change with the fresh OS. Compilation is fine, the module does not load on it's own at OS start but can be invoked with modprobe 8822bu. After plugging in the Nano, however, there is no change from the original post.

[brandon-bailey]

What usb wireless device are you using? From the device id you described it appears to be ASUS USB-AC68 Dual-Band AC1900, and should not be using this driver.

[mahatah]

I'm using the "ASUS AC-53 NANO". The exact device is this one: https://www.asus.com/Networking/USB-AC53-Nano/

I believe this is the same device as the one listed on the README page of your Git repo?

[jeremyb31]

Looks like Brandon fixed it so you should be able to go into the rtl8822bu directory in terminal and do a git pull make clean make sudo make install And have it working again after a reboot

[lkw16]

Assuming below is the correct VID:PID for the ASUS adapter.

Bus 002 Device 006: ID 0b05:184c ASUSTek Computer, Inc.

And if the adapter is indeed using RTL8822BU chipset, shouldn't the descriptor be under #ifdef CONFIG_RTL8822B section instead of '#ifdef CONFIG_RTL8812A' in usb_intf.c' file? The Makefile only configures for 'CONFIG_RTL8822B = y'.

However, I'm just guessing here...

[mahatah]

@jeremyb31 This was already tried as per my responses. I even went so far as to try the changes made on a fresh OS. This did not work.

@lkw16 I hadn't noticed that. Good catch. I can try recompilation after making that edit and post back if there is any change. Thanks for the post.

[mahatah]

@lkw16 You sir, are a gentleman and a scholar! Your suggestion works!

@brandon-bailey and @jeremyb31 the following two sections of 'usb_intf.c' were edited as per the advice of @lkw16

Thanks again to everyone who helped me solve this. I really appreciate it. Driver is working great! Thank you!
