FS#2992 - USB problem on bcm6318

xchetah:

Hi
I'm using openwrt on bcm63xx bcm6318 sagemcom F@ST 2704N V1.
the router is actually V1.1 (16MB flash , 64MB RAM).
trying to connect a usb wifi dongle as AP

the problem is that there's no connectivity at all , I can connect to the AP (only without encryption ) and the ssid doesn't always show on my mobile phone.
the usb port is working fine , I tried mounting a usb flash drive with no problem.
also the adapter is working , I tried it on Orange pi , Raspberrypi , bcm6328 , all with openwrt installed on them and didn't have any problem .
I guess it is something related to bcm6318 or its architecture code .
the onboard broadcom pci wifi is working .
I suspected that its a power problem so I added an external usb power , but with same issues.
also I tried openwrt 19 ,18 ,17 with same problem.
I'm also using two bcm6328 routers as point to point wifi 5ghz link with Ralink RT5572 chipset ( rt2800usb driver ) withouyt any problem.
dmesg is filled with :

using rmmod to remove rt2800usb module results in kernel crash /sometimes hang and sometimes panic and reboot.

steps to reproduce:
-boot the router with usb wifi dongle
-configure it as access point and enable it

• dmesg log starts to fill and adapter is not working

When googling, the standard explanation for the warning is "insufficient power" indeed, however they have a different error code.

Anyway, this is a kernel issue, so we won't be able to help much.

You can only try to build an image from master with testing kernel enabled (in make menucnonfig -> Global build settings -> Use testing kernel version). This will give you kernel 5.4, maybe there has been a fix there in the meantime.
