Yes, I have two plugged in and they're working fine. However, perhaps my custom rules are preventing them from showing up: SUBSYSTEM=="tty", DRIVERS=="pl2303", KERNELS=="4-1:1.0", KERNEL=="ttyUSB*", SYMLINK="mythser/rca1" SUBSYSTEM=="tty", DRIVERS=="pl2303", KERNELS=="3-3:1.0", KERNEL=="ttyUSB*", SYMLINK="mythser/rca2" I'm not sure if rules are additive - if these symlinks would show up in addition to whatever other ones are created by other rules, or if these would be exclusive. I hard-coded them to specific physical USB ports so that they would be persistent. If I plug them in elsewhere they still get ttyUSBn devices, but no symlinks. Rich
