Fail to connect with 8723du

[vhenriet-sfy]

Hi,

I'm trying to make this driver work with a 8723du module.
I'm using the branch sync-with-backports/v5.10 on a 5.10.37 kernel.

When I plug the module, I can see that no hw mac is set. No errors in logs.

[20408.332035] rtw_8723du 5-1.3.1.1:1.2: Firmware version 48.0.0, H2C version 0

I set manually the mac address, using real device mac, with this command
sudo ifconfig wlan0 ^C ether xx:xx:xx:xx:xx:xx

The, when I try to join a network, I got lot of these errors :

[21055.229853] rtw_8723du 5-1.3.1.1:1.2: failed to wait usb ctrl req:192

[21056.196854] rtw_8723du 5-1.3.1.1:1.2: failed to wait usb ctrl req:64

And of course, the join failed :

[20684.867163] wlan0: authentication with yy:yy:yy:yy:yy:yy timed out

I guess that something is missing regarding the mac address issue.
Any idea on the failed to wait usb ctrl req:64 error?

I see this as well, but I don't eve see the "send auth" messages. It scans ok, but nothing can be joined. Setting up an AP fails as well:

karlp@strem:~$ nmcli dev wifi hotspot ifname wlp0s20f0u3i2 ssid test8723 password "test1234"
Error: Connection activation failed: (4) The device could not be readied for configuration.
karlp@strem:~$

with the kernel log just full of

The start/stop vif's correspond to any attempt at activating an interface, but the 64/192 failed ctrl reqs are a steady stream.

tested with 8821cu
This is a general usb problem, I'm facing.
I need to review the code of the control requests.

[ulli-kroll]

Please use latest -master
I've use code from rtlwifi which is more robust.

8821cu connects to my AP, but no DHCP
one down, one to go

[vhenriet-sfy]

I made the test whith the laster -master with a 8723du.

Errors lile "failed to wait usb ctrl req:192" are gone, but things are still not working

The mac address is still not set automaticaly, (got ff:ff:ff:ff:ff:ff).
I can set it manually.

I can scan for network and got somme results.

I can't join a network, it timeout when triing to authenticate with the AP.

Let me know if I can provide you more information.
