Oh yes, there are. Either Unstable's udev or something else does this for USB at the very least. Noticed it when playing with a Huawei E220 HSDPA USB modem, the usb.ids information ended up in /dev/serial/by-id. Here's the proof (output edited for brevity): khazad-dum:~$ lsusb ; ls -l /dev/serial/by-id/* Bus 004 Device 003: ID 12d1:1003 Huawei Technologies Co., Ltd. E220 HSDPA Modem / E270 HSDPA/HSUPA Modem lrwxrwxrwx 1 root root 13 2009-09-07 14:56 /dev/serial/by-id/usb-HUAWEI_Technologies_HUAWEI_Mobile-if00-port0 -> ../../ttyUSB0 lrwxrwxrwx 1 root root 13 2009-09-07 14:56 /dev/serial/by-id/usb-HUAWEI_Technologies_HUAWEI_Mobile-if01-port0 -> ../../ttyUSB1 Now, I am not claiming it it is not useful. However, IMO it would be useful *and* safe if I had a by-id link using the proper USB ID *numbers* instead, which I could use on /etc/ppp/peers/* for example. -- "One disk to rule them all, One disk to find them.
