Hi guys,

I tried to follow wiki , but ifconfig -a does not show any usb network.

Here something that may be relevant:
If I use my usb port with a memory stick I find the device in /dev/sdb1; if I plug the phone in the same port to access the storage I cannot find the device.
As usual, any help is highly appreciated.

Efo,
The easy one first. Your phone uses the FAT filesystem. You cannot have it mounted in two places at the same time.
To see the phone as USB storage, you need to unmount the storage from the phone.
My HTC raises a pop up to ask what I want to do when I connect it to my PC.
USB tethering is harder. You will need CDC support, PPP support and either Ethernet over USB support or usbserial support.
Your phone will either show up as a couple of USB serial ports, one of which acts like a 56k modem, only faster, or you will get a new interface in ifconfig -a.
Normally it would bu usb0 but udev is sure to rename for you.
Its possible that the kernel does not know your Vendor and 0x22b8 and Product 0x2e82 IDs, so you may need a small kernel patch.

| Your phone provide a MTP device only, you need to enable USB network sharing under the WIFI-AP menu. On Linux side, you should enable CONFIG_USB_NET_CDCETHER and CONFIG_NET_RNDIS_HOST. |

Hi all and thank you for your help,
s4e8:
thank you for the tip, it looks like it is MTP and PTP only. CONFIG_USB_NET_CDCETHER and CONFIG_NET_RNDIS_HOST were alreade set as modules.
I ended up using mtpfs:
1) connected moto g to my computer and made sure it was on MTP in settings -> storage -> "USB computer connection" (from top right menu)
2) got product and vendor id (can use lsusb -v or mtp-detect), my device is 22b8:2e82 (see above)
3) added
SUBSYSTEM=="usb", ATTR{idVendor}=="22b8", ATTR{idProduct}=="2e82", MODE="0666"
to /etc/udev/rules.d/80-android.rules
4) uncommented "user_allow_other" in /etc/fuse.conf
5) rebooted
6) now I can mount it as: mtpfs -o allow_other /mnt/usb
NeddySeagoon:
thanks for the info here is what I have:
grep CDC .config
| Code: |
CONFIG_USB_NET_CDCETHER=m
CONFIG_USB_NET_CDC_EEM=m
CONFIG_USB_NET_CDC_NCM=m
# CONFIG_USB_NET_HUAWEI_CDC_NCM is not set
# CONFIG_USB_NET_CDC_MBIM is not set
CONFIG_USB_NET_CDC_SUBSET=m
|
grep PPP .config
| Code: |
CONFIG_PPP=m
CONFIG_PPP_BSDCOMP=m
CONFIG_PPP_DEFLATE=m
CONFIG_PPP_FILTER=y
CONFIG_PPP_MPPE=m
CONFIG_PPP_MULTILINK=y
CONFIG_PPPOATM=m
CONFIG_PPPOE=m
CONFIG_PPP_ASYNC=m
CONFIG_PPP_SYNC_TTY=m
CONFIG_HDLC_PPP=m
|
Something missing?
By the way, if you know how to tether over bluetooth it is even better. I tried that first with butbluetoothctl, but I just couldnt connect it (it would pair easily, but not connect). |

You must enable ethernet sharing on the phone side. When you plug you phone, you may
1. pop up a choice of MTP, PTP, USB storage, or mobile network, etc..， you should choose mobile network.
2. or enable USB tethering inside system settings --> more --> tethering & mobile hotspot. |

s4e8,
when I plug the phone in I have only MTP and PTP options (carriers tend to block tethering and such on the phones that they provide nowadays), same for settinge --> more (no tethering and mobile hotspot)
I am just trying to get some tethering working for very occasional use. I am not sure whether these options are disabled in the kernel or not... |
