Mine (yes, I have a bunch of USB devices) reads as: I believe Debian is setup to create those OSS compatible devices whenever possible. In any case, it's not just /dev/dsp that is missing. If I do for instance `aplay -l', I just see the my internal card: **** List of PLAYBACK Hardware Devices **** card 0: I82801DBICH4 [Intel 82801DB-ICH4], device 0: Intel ICH [Intel 82801DB-ICH4] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: I82801DBICH4 [Intel 82801DB-ICH4], device 4: Intel ICH - IEC958 [Intel 82801DB-ICH4 - IEC958] Subdevices: 1/1 Subdevice #0: subdevice #0 So, it appears to me that I need to do something else to activate the device. This page talks about a `usx2yloader' that I should run: http://www.ubuntuforums.org/printthread.php?t=30891 I've installed it and ran it, but it doesn't seem to find the device either: $ sudo usx2yloader usx2yloader: no US-X2Y-compatible cards found (Yes, I've tried to do the fxload stuff above it manually, too.)
