Kmod-rtl8812au-ct stop working Luci

For Developers
1

I bought several USB sticks, Dual band, AC
Some have the chip RTL8111AU or CU
I'm trying to compile a driver at a time, hoping that it might work.

I can do a few proveal day, there`sa way to do first ?
Even if I enable this, there are not as many modules in the compilation, and there are no drivers.
Global Build Settings ---->
Select all taghet
Select all

If I enable many driver, all stop working

When I enable "kmod-rtl8812au-ct" Luci stop working and says
Bad Gateway
The process did not produce any response

Same with or whitout Stick
At insertion of the stick, dmesg says
[ 866.680425] usb 1-1: new high-speed USB device number 2 using ehci-platform

But because no one helps me solve this problem?
Someone put these drivers in the system.

I tried to just put kmod-mt76x0u
The system has successfully started, Luci work well, I put the key and it appears a new radio.
Until here all right.
I turn the radio on, the system restarts continuously.

Help Please

Same problem with minimum module enabled.
Only Luci and usb driver.

make distclean
./scripts/feeds update -a
./scripts/feeds install -a

make menuconfig   (.config)

	Subtarghet  "RT5350"

How do I open this case as a bug to be solved?
I do not know if the bug is in the kernel or modules.

Why ?
This driver not not from one of the core openwrt team.
Maybe you should contact the author of the patchset who send this to openwrt mailinglist
But I have doubts (s)he can help you.

Anyway the error/bug is in the driver module of your device.
To debug this you need to analyze the code, and test first without Luci.

For me this is not my code and this is a jaguar1 design from Realtek.
Currently jaguar2 PCIe chip are upstream, only the USB part is missing.

So much to say :wink:
