HOWTO: Access Motorola phones through USB on Hoary using Moto4Lin

**mlenis** · March 11th, 2007

[info] Switching device /dev/usb/acm/0 to P2K mode...
[error] Unable to open device
[error] Please check preferences

This is what im getting now.

Can anyone tell me why I cant connect to the phone?

When I click on update lis in preferences my phone shows up with a Vendor ID, Product ID, Manufact. and product. So to some degree it is pulling information from th phone.http://ubuntuforums.org/images/smilies/confused.gif

Thanks for the guide, I've got my Motorola L6 hooked up and working now. I kind of used a hybrid of this guide and the one on the wiki. This is exactly what I did

Code:

sudo aptitude install libqt3-mt-dev zlib1g-dev libusb-dev
svn co https://svn.sourceforge.net/svnroot/moto4lin/trunk/moto4lin moto4lin
cd moto4lin/
qmake
make
sudo make install
sudo chmod u+s /usr/bin/moto4lin

I'm having the same problem. I installed everything according to the instructions, but it just refuses to connect.

I'm using a Moto Razr v3i
This is what I get when I open with the Terminal:

Code:

#sudo moto4lin
X Error: BadDevice, invalid or uninitialized input device 169
  Major opcode:  149
  Minor opcode:  3
  Resource id:  0x0
Failed to open device
X Error: BadDevice, invalid or uninitialized input device 169
  Major opcode:  149
  Minor opcode:  3
  Resource id:  0x0
Failed to open device
Form1
PhoneMan
New mode: 2
New mode: 1

I have no idea what any of that means, and I'm an optimistic fool, so I went ahead and tried everything as per the instructions anyway.

I try to switch the device to P2K, and get this problem:

Code:

[info] Phone pluged as P2K
[info] Phone pluged as AT
[info] Switching device /dev/ttyACM0 to P2K mode...
[error] Unable to open device
[error] Please check preferences

Doesn't look good. I try connecting anyway:

Code:

Try to connect
[info] AT phone found
[info] Switching device /dev/ttyACM0 to P2K mode...
[error] Unable to open device
[error] Please check preferences
[error] Unable to connect

So now I'm stuck.

I have problems getting this working. Can anyone help?

Moto4lin version: No version number, built from SVN on 3 April 2007
Distro: Ubuntu Edgy
Phone: Motorola V360

Here's what happens when I follow the instructions.

Terminal:-

Code:

jem@fawkes:~/t/moto4lin$ sudo moto4lin 
X Error: BadDevice, invalid or uninitialized input device 166
  Major opcode:  144
  Minor opcode:  3
  Resource id:  0x0
Failed to open device
X Error: BadDevice, invalid or uninitialized input device 166
  Major opcode:  144
  Minor opcode:  3
  Resource id:  0x0
Failed to open device
Form1
PhoneMan
New mode: 2

Logging in moto4lin:-

Code:

Phone is unpluged. Please connect it
Phone pluged as P2K

Already this has diverged from the instructions. Should be plugged as "AT"

In Preferences I set ACM Device = /dev/ttyACM0

I click View List and find an entry for Motorola Phone (V360). Vendor ID = 22b8, Product ID = 4810.

I click Switch to P2K. Logging in moto4lin says:-

Code:

error unable to open device
error please check preferences

Then, at a guess, I try plugging in product and vendor IDs at random. Nothing makes a difference.

I hope someone can help me please!
Thanks
Jem

Ok, I have gotten my phone to connect. I can add ringers, and pictures, but I can't seem to access my phone book. Also how would I add a java program. I have a Razr V3. Any ideas? I'm a little more interested in the phone book as I don' t have any java programs to add right now, but I'm sure there are some games out there I could add somewhere. Thanks.

I'm running Feisty beta fully updated and installed Moto4lin from Synapatic.

Phone is recognised correctly as RAZR V3x in the preferences usb list.

This is all I get in the information window:

Code:

[info] Phone pluged as P2K
[info] Phone pluged as AT
Try to connect
[info] AT phone found
[info] Switching device /dev/usb/acm/0 to P2K mode...
[error] Unable to open device
[error] Please check preferences
[error] Unable to connect

and this in terminal:

Code:

rob@Ubuntu:~$ sudo moto4lin
X Error: BadDevice, invalid or uninitialized input device 171
  Major opcode:  149
  Minor opcode:  3
  Resource id:  0x0
Failed to open device
X Error: BadDevice, invalid or uninitialized input device 171
  Major opcode:  149
  Minor opcode:  3
  Resource id:  0x0
Failed to open device
Form1
PhoneMan
New mode: 2
New mode: 1
doActConnect
doActConnect
P2kProc::doConnect()

Does anyone have any suggestions (other than get a new phone)

Okay, I've followed that, but I can't get it to connect. It sees the phone in AT mode, but when it tries to switch to P2K mode, it never works. I've written down the vender ID info correctly -- what should i do next?:

[info] Phone is unpluged. Please connect it
[info] Phone pluged as AT
Try to connect
[info] AT phone found
[info] Switching device /dev/ttyACM0 to P2K mode…
[error] Unable to connect
