Tested this in ubuntu 11.04. The device name is not changed, and lirc works after resume, if neither irexec nor irxevent is running. If either one is running, device is changed in resume. A workaround is to unplug and re-plug the USB device. Then /dev/ttyUSB0 exists again and lirc works. The remote control in question is "VLSystem MPlay Blast".
** Description changed: - Update: As for Xubuntu 10.04 at least, please read comment #5 + Update: As for Xubuntu 11.04 at least, please read comment #13 OS: 8.10 USB device is attached to /dev/ttyUSB0 when I plug it in USB port. But when I suspend to RAM and resume, it gets attached to /dev/ttyUSB1. Consequently, the daemon configured using /dev/ttyUSB0 does not work after resume. I would expect the device to be attached to the same ttyUSB before and after.
