Portal 2.4 Ubuntu 10.04 unable to connect

[nathangray]

I'm trying to connect to a SnapStick using Portal 2.4 under an upgraded Ubuntu 10.04. The GUI gives these errors:

I've tried setting the python lib directory to /usr/lib/python2.4 with no change.

Do you see this error when you first start Portal or after you try and connect to the SNAP Stick?

That was when I tried to connect. Today it's different after I've restarted.
Now I get

I'm assuming this SNAP Stick works on another PC? Also, does the user your are running Portal as have access to read and write from /dev/ttyUSB0?

Yes, also used to work on this PC using Portal 2.2 and Wine.

User has permissions.

[mgenti]

Yes, also used to work on this PC using Portal 2.2 and Wine.

So this just recently stopped working?

I retested Portal on a Ubuntu 10.04 box with a SNAP Stick and could connect with no problems.

It was doing testing onsite for a few weeks with a windows machine, now it's back on my desk.
Now neither Portal 2.2 over Wine nor Portal 2.4 for Linux can find the snapstick.
I've tried with 2 nodes.

I retested Portal on a Ubuntu 10.04 box with a SNAP Stick and could connect with no problems.

That's not good news for me.

Could old firmware be an issue? The nodes are probably still at 2.2 or earlier.

[mgenti]

Yes, it is worth updating since there have been some changes on how we to talk to the nodes.

[nathangray]

I updated the firmware, but my with my laptop I still cannot connect to/through the stick. I've used another Ubuntu 10.04 box to connect via RS232 and USB, so the hardware's fine; it's something with my laptop.

Any ideas what to check?
Both machines are upgrades to 10.04 from previous release.

[nathangray]

This evening I tried out a 10.4 live CD, and it worked.
When I booted back to my 10.4 installation, I was able to connect.

Weird.

[Jheath]

Weird, but working.

Not always a bad pairing.

Glad you've got things up and running.
