Grayed Out Serial Port (Again)

Okay this time I'll try to post my problems better. Thank you guys for helping all the newbs like me! I'm running Ubuntu 12.04 x64 and maple-ide-0.0.12 linux64.

I can upload sketches to the Maple Mini fine, and during this part of the process the Serial Port tab is not grayed out. After uploading, the IDE spits out:
```
Opening USB Device 0x1eaf:0x0003...
Found Runtime: [0x1eaf:0x0003] devnum=48, cfg=0, intf=0, alt=1, name="DFU Program FLASH 0x08005000"
Claiming USB DFU Interface...
Setting Alternate Setting ...
Determining device status: state = dfuIDLE, status = 0
dfuIDLE, continuing
Transfer Size = 0x0400
bytes_per_hash=306
Starting download: [##################################################] finished!
state(8) = dfuMANIFEST-WAIT-RESET, status(0) = No error condition is present
Done!
Resetting USB to switch back to runtime mode
```
After that the Serial Port tab is grayed out and unusable. This would normally be fine but my current project requires it to communicate with UART to a Beaglebone, and I want to debug it on my PC (basically print out what it is receiving from Serial1 to SerialUSB).
When I run the install-udev-rules.sh
sudo bash '/home/zachary/Desktop/maple-ide-v0.0.12/install-udev-rules.sh'
the terminal spits out
`Copying Maple-specific udev rules...
cp: cannot stat tools/45-maple.rules': No such file or directory

I've also followed the instructions from http://forums.leaflabs.com/topic.php?id=91 to no avail. Any ideas/suggestions on what to do?

Hi Chrome,

Did you try running install-udev-rules.sh from inside the directory /home/zachary/Desktop/maple-ide-v0.0.12/? Can you confirm that you have permissions to connect the serial port with a program other than the IDE? Eg, screen /dev/ttyACM0 (sudo apt-get install screen; Ctrl-K to quit)?

Please note that debugging over SerialUSB might be a bit tricky if you are trying to catch messages that are transmitted before the host OS can connect to the port.

See also the SerialUSB docs on "safe" printing:

Just to verify that I'm running install-udev-rules.sh in the directory `/home/zachary/Desktop/maple-ide-v0.0.12/' I entered these commands into the terminal:

`cd /home/zachary/Desktop/maple-ide-v0.0.12/'
sudo bash install-udev-rules.sh

The same thing happened: the serial port worked until I uploaded to the board.

Screen works fine (screen /dev/ttyACM0)

Update: The problem no longer occurs if after the upload I click the reset button.

Well i'm stumped as to why install-udev-rules.sh would throw you that error; is the file ./tools/45-maple.rules actually missing for you? I just re-tested with a fresh download of the linux64 0.0.12 release and it worked fine for me.

Regarding the serial port not showing up after an upload until the board is reset, sorry this was intuitiveness and frustrating. I think the resolution will probably be the same as for this issue: https://github.com/leaflabs/maple-ide/issues/52
