OK, that is weird. These random effects usually mean power issues. Is your usb hub self powered?

- Try connection only 2 devices, set them in serial app and reboot several times.
- Try again with only 2 different devices.

If all your devices are detected when connected individually but it does not work when all are connected you will have the confirmation of a power issue.

Yes Sailoog, the hubs I am using are self powered.
Anyway the last test I made it was with only two devices connected with no hub, this excludes definitely a power issue.

Could you send the output of the command lsusb when the devices are detected and again when they are not?
