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".
