Hi all,
I am writing here, even if it is bananapi related problem, since I love gentoo and I know that this community is more active and able to resolve problem.
I am trying to understand why, and in this case it is a linux general problem, if I put 2 wifi dongles they are not recognized, but trying one each time and on both usb (banana has 2 usb) they works: This is what I have written in all bananapi related forum (without receiving a response):
--------------------------------------------------------------------------------------------------
I am trying to use 2 identical dongles on my banana without success.
If I use one dongle at time it works, but both are not working even if dmesg is finding that in the same way it does with the working one.
I saw other cases on raspberry (even if you use different wifi chipset) and someone resolved blacklisting driver, but for me it seems very strange.
I tried to get it up manually without success (link bla bla doesn't exist).

EDIT: I forgot to say that I am using one dongle as AP and one as client.

For me 3 can be problems:
1. Limit/bug of Bananian
2. udev rule on same chipset that prevent to activate the second wifi dongle
3. Protection mode due to too much consumption of energy
----------------------------------------------------------------------------------------------------

And this is what I discovered with dmesg:
----------------------------------------------------------------------------------------------------
Looking at my dmesg, I discovered something strange:
[ 2.310912] usb usb4: New USB device found, idVendor=1d6b, idProduct=0001
[ 2.327923] usb usb4: New USB device strings: Mfr=3, Product=2, SerialNumber=1
[ 2.341209] usb usb4: Product: SW USB2.0 'Open' Host Controller (OHCI) Driver
[ 2.352847] usb usb4: Manufacturer: Linux 3.4.104+ ohci_hcd
[ 2.361536] usb usb4: SerialNumber: sw-ohci
[ 2.392579] usbcore: registered new interface driver usb-storage
[ 2.431750] usb 1-1: SerialNumber: 00E04C0001
[ 2.584735] usb 3-1: new high-speed USB device number 2 using sw-ehci
[ 2.755070] usb 3-1: New USB device found, idVendor=0bda, idProduct=8179
[ 2.773750] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 2.783829] usb 3-1: Product: 802.11n NIC
[ 2.790871] usb 3-1: Manufacturer: Realtek
[ 2.798259] usb 3-1: SerialNumber: 00E04C0001
[ 2.868288] usbcore: registered new interface driver usbhid
[ 2.876696] usbhid: USB HID core driver
[ 16.018871] sw_usb_enable_hcd: usbc_num = 2
[ 16.579994] usbcore: registered new interface driver rtl8188eu
------------------------------------------------------------------------------------------------------

lsusb shows me that both usb are correctly recognized as Realtek, but using usb-devices on the second usb it says Driver=(null). It seems like for some reason it cannot configure the second dongle.
I also checked udev rules and in the KERNEL filter is specified |wlan*[0-9]|

Sorry if I am breaking gentoo rules, but I am very frustrated since this should be a very smooth step requiring no extra work... :(

DevOne,

I suspect the you bananapi connot power both devices at the same time.
Typically, USB wifi dongles want 500mA from the USB port. Thats as much as one USB root hub can provide.

If you use a powered hub, do they work then?

Hi,

Now I am trying just to put one, and it is not able to configure it!

DevOne,

Do you have the fimware?

USB WiFi devices normally need firmware.
Look in dmesg to see if the firware failed to load.

DevOne,

As you are on Ubuntu/Linaro rather than Gentoo, which you brought to our attention is your first post.
I assume that you are on a fully modular kernel.

You can confirm that by looking for the rtl8188eu module in the output of lsmod.
rtl8188eu does indeed requre firmware. It is called rtl8188eufw.bin and will be found either in /etc/firmware/rtlwifi/ or /ib/firmware/rtlwifi/.
If you don't have it, thats the first hurdle to overcome. Its found in linux-firmware.

After that, you will need wpa_supplicant to take care of getting associated with your access point.

Hi,
This is debian based and yes I have a working 8188eu module. Only one wlan will be created by bananian, so it means driver and so on are working...my problem is that if I put 2 dongles only one will be created even if bananian correctly identifies both

DevOne,

Do you mean that you do not get wlan0 and wlan1 in dmesg?
I suspect a USB bus power problem.

Yes, despite dmesg recognized well all of those, I can see only one wlan up and running. I don't know if it is a limit in power, a bananapi has 5v and 2A DC and only 2 usb slots (against rasperry that has 4 usb and it seems able to run more dongles at same time)...

I don't understand why (other then this new warning at biginning), despite it recognized both, only one driver is associated to an usb, and why instead it loads usb-storage!

Well spotted.

Some USB devices pretend to be CDROMs. These CDROMs hold the windows drivers.
The windows drives switch the devices to the real functionality.

Try usb_modeswitch. The device will change its device ID if this is the issue and should appear as wlan1

I will do it...but I thhink, at this point, that is a bug somewhere in bananian OS; for example, I found this kind of rule for udev (of course I put my module):

Code:
SUBSYSTEM="usb", ATTRS{idVendor}="xxxx", ATTRS{idProduct}="xxxx", RUN+="modprobe 8188eu"


putting my wifi dongle's idVendor and idProduct, i should force kernel to load that module.

this can help me, but where do I have to put this in?
