Description
The Analyzer was connected correctly with your system and both red state LEDs are on. After starting the software, the startup dialog reports an error (MSB not found).
1. Check your permissions
Linux handles the analyzer as a serial USB device like /dev/ttyUSB0 and you need read/write permissions to access the device. Except for root only members of the group dialout (Debian based systems, newer OpenSUSE) or uucp (SuSE) can do this. Open a terminal (with an connected analyzer) and type:
ls -l /dev/ttyUSB*
You will get something similar like this:
crw-rw---- 1 root dialout 188, 0 2009-08-26 14:47 /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 2009-08-26 14:47 /dev/ttyUSB1
...
If there is no /dev/ttyUSBx device listened the udev rule add by the analyzer software installer already skips the detection as a virtual serial port (to operate the analyzer via a USB direct access). In this case please just go ahead with the next step.
Check your group memberships by input the command:
groups
The following result indicates, that you are member of your own group (YOUR_USER_NAME), the groups cdrom, floppy, audio, video and plugdev. But your are not member of the required group dialout (or uucp) which you need to access the analyzer device.
YOUR_USER_NAME cdrom floppy audio video plugdev
To add yourself to the group dialout you must execute the following command via sudo. (In case you have not sudo rights, ask your system administrator).
sudo adduser YOUR_USER_NAME dialout
Please note! You have to logout and new login first until the changes are available. A reboot is not necessary.
2.Check for an installed Braille driver
You have the correct permissions for accessing the /dev/ttyUSBx device. Anyhow the analyzer wasn’t detected by the software. Be sure, that you don’t have an installed Braille driver. Disconnect and connect the analyzer again. Open a console and input dmesg. If the output displays something like this:
Detected FT232BM Feb 11 16:14:59 sd kernel: [ 1575.765756] usb 3-2:
FTDI USB Serial Device converter now attached to ttyUSB0 Feb 11

disconnected from ttyUSB0
a Braille driver is part of your system. If you have no need for a Braille device, please remove it from your system. On Debian based systems a:
sudo apt-get remove brltty
should work.
Both solutions don't work
Please help us with conflicting devices.
The firmware loader uses the information which is collected in the USB enumeration procedure to detect all serial ports connected to a MSB-analyzer. Because of the manifold combinations of existing USB devices and drivers we can not exclude the possibility that in rare cases the program does not detect the analyzer correctly. To regard these situations in the further program development we need your active help.
Open a command shell (terminal) again and change to the installation directory.
Enter the following command:
./msb_serv --verbose
The --verbose parameter forces the program to store the report file AnalyzerScan.txt with information concerning the internal analyzer detection on your desktop. It is a plain ASCII text file and you can open it with any editor. Just send this file afterwards to support@iftools.com.
