z6c and Linux

(Click here to view the original thread with full colors/images)

Using the V710m profile on my MPT works fine with my laptop on WindowsXP. I was able to copy some photos I snapped from the phone to my PC, and I was able to use it as a modem.

But on Linux I don't get anything from it; it doesn't register as a modem or anything else. Any ideas?

Also, my K1 had a menu option for switching the USB connection from Modem, to Storage, to Printing mode. The z6c doesn't have any of these menu options. Is there a SEEM edit to enable them?

Looks like they've programmed this thing to advertise an undefined device class. Very annoying.

I have the same problem, Emailed Moto Tech support, and told them I use Ubuntu 8.04 Debian based Linux Distrobution, they responded with "What version of windows are you using?" so help from them is out...
does your ssudo dmesg output look like this
Code:

[  517.503081] usb 3-1: new full speed USB device using uhci_hcd and address 4
[  517.544857] usb 3-1: configuration #1 chosen from 1 choice

You need to load the usbserial module with the vendor and product options for your particular phone. For my W755, the process looked something like this:

Get vendor and product ID:
# lsusb |grep -i moto
Bus 003 Device 060: ID 22b8:2b44 Motorola PCS

Tell modprobe to load usbserial for this device. Method varies from dist to dist:
alias usb:v22b8:2b44* usbserial
options usbserial vendor=0x22b8 product=0x2b44

Then when the module is loaded with those parameters, you'll get a device file for the phone. You may get two devices (I do for the W755, but not for the E815), if so, use the first. From /var/log/messages:

Aug 14 23:45:20 jama kernel: usb 3-2: generic converter now attached to ttyUSB0
Aug 14 23:45:20 jama kernel: usb 3-2: generic converter now attached to ttyUSB1

For the E815 the device is /dev/ttyACM0, but varies from phone to phone and system to system. I'd guess that any of them with the microUSB plugs will show up as /dev/ttyUSB*.
