expeyes hardware not found

Asked by David Boertjes

I have installed expeyes on my Ubuntu 14.04 TLS machine on a 64bit pc. The program always reports that the hardware is not found. I have tried with and without the .rules file from the postinst script, and neither work. Here is the output from the terminal:

david@david-Satellite-C650D:~$ sudo expeyes
[sudo] password for david:
/usr/share/expeyes/eyes
/usr/share/expeyes/eyes

Port /dev/ttyACM1 is existing and opened. No EYES hardware detected
Could not find Phoenix-EYES hardware
Check the connections.
/usr/share/expeyes/eyes
0.0

I have a TI Launchpad which is working but I believe may use the same USB-toSerial chipset. I looked at the device IDs in the rules and I think they don't overlap but I am no expert. Here are the two .rules files.

david@david-Satellite-C650D:/etc/udev/rules.d$ cat 99-phoenix.rules
SUBSYSTEM=="usb",ATTRS{idVendor}=="03eb", ATTRS{idProduct}=="21ff", MODE="666"

You first need to buy the ExpEYES or ExpEYES Junior hardware.....

Mark;

Thanks for your suggestion, however, I do have the hardware, and it is connected to the USB port. It is a dual boot PC and it I can get the software working in Windows on this machine, but not Ubuntu. I have a compiler on Ubuntu I want to use for other work, so it would be advantageous to not have to reboot into a different OS to use Expeyes.

I apologize for not being more specific.

Cheers,
Dave

Problem solved. I have had this thing for 3 months and didn't notice the "Junior" on the case! I suppose I'm just lucky that it worked at all with Windows given my oversight. I have it working now on both. Thank you for your help and bringing me back to simpler thoughts!

Cheers,
Dave

What did you do to get it working on Ubuntu?

To fix the problem, instead of issuing the command "sudo expeyes" I am now using "sudo expeyes-junior", which is the correct command for my version of the hardware. Really this was all my mistake. However, I suppose that as an enhancement, we could ask for a feature to check for the other type of hardware in each program and provide a message to the user that the hardware detected is of a different type, e.g.:

Message now: "Hardware not detected - please connect USB cable and restart this program"

Enhanced message: "Expeyes Junior hardware detected - please close this program and launch /usr/bin/Expeyes-junior"

In addition, the junior version of software could check for the Expeyes hardware and give the appropriate message.

Thanks again for your help and quick replies.

Cheers,
Dave
