[USB tethering] LG E411 not working

[bipolar]

Seing the inclusion of the new usb_rndis driver, I've attempted to use the two (rather old) Android 4.1 smartphones I have access to.

This ticket is for the one that under Linux works as a USB CDC EMC/AMC device.

An LG L1 II (E411, Android 4.1): Under Linux it works for USB tethering using the cdc_ether driver (I blacklist the cdc_acm driver, because otherwise it treats it as a 3G modem).

Under Haiku, it doesn't seems to work (no device appears under /dev/net/usb_ecm/).

Of note: when connected via USB, this phone presents it self as a CD-ROM device (that's how it tries to install its Windows drivers) until I hit "Skip installer" in a dialog that appears on the phone, and "OK" on a dialog asking if I'm sure I want to enable USB tethering. It does that everytime you plug it in (annoying and unavoidable).

I mention this because it might be part of the problem, as the syslog shows something like this after plug it in, and doing the "skip" and "ok" on the relevant dialogs on the phone:

I'm attaching the output of listusb -v /dev/bus/usb/6/2 under Haiku hrev55112, and sudo lsusb -v -d 1004:61fe under Linux, just in case (plus `lsmod | grep usbnet).

On both cases is with USB tethering already enabled (and working in case of Linux).

The ECM driver detects the device but does not manage to use it, it seems. The "cdrom" should not be a problem then?

I only mentioned that CDROM because of the line:

KERN: usb error hub 32: new device on a port that is already in use

made me think that perhaps something goes wrong while "switching modes" (some device not being properly closed?), but... no idea, really.

maybe try on a usb3 port.

[pulkomandy]

The "port that is already in use" message is normal and expected in that situation. The listusb output you attached shows us that the phone switched to the communications mode, so everything seems fine on that side.

Sadly, I won't be able to. All the hardware I have access to is rather ancient and USB 2.0 at best :-/ ("newest" is an Atom N450 based netbook from 2012, next one a 2010 Athlon II X2 based desktop).

Thanks for the explanation! Maybe that message could be reworded to that effect? Low prio, I know :-)

As usual.... thanks for your work guys. Much appreciated!

My beloved tiny LG E411 finally kicked the bucket some months ago. Good bye old friend, sniff.

Guess this ticket should be closed? (somehow I doubt anyone else would have a working one to test at this point).

Oh well! We can reopen if someone else does.
