** Description changed: + Update: As for Xubuntu 10.04 at least, please read comment #5 + 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.
