hwd -e does not list connected USB devices

USB devices for audio in/out not recognized in hwd -e.

Desired USB Items appear in KDE INFO CENTER: SOUND.

KDE MIXER alternate...USB Mixer... shows OUTPUT  PCM icon but no INPUT device  is shown (thus, no device is connected).

System has udev installed but uncertain whether root permission is provided for the USB devices...namely...USB MIXER and SND-USB.

Spent many hours in stupid search for ...audio group....and ...optical group...
when the reference name for the "group" is...audio devices... and ....optical devices...  This is a common problem in searching out posts..improper nomenclature references.

A listing for ...mixer...is provided but none for ...usb mixer...

Can I assume that all entries in the udev permissions file permit immediate use by root?  Do they have to be edited to function?  The indications are that root owns them all and doesn't need permission.

Sure would like to get USB audio running!!!

Are there special requirements for the USB devices?

Re: hwd -e does not list connected USB devices

What type of USB audio device(s) do you have?
Run "hwsetup -v -n" to check if the device is recognized. If not, then try lshwd (new detect engine for hwd, still under development).

Re: hwd -e does not list connected USB devices

Primary audio device of interest is SIIG USB Soundwave Optical 5.1 with both optical port and stereo audio port.

Listing of hwsetup -v -n shows two entries for Audio USB.

Am going to test for audio from a CD now.  Am able to use the device in windows and in Knoppix and in Stux Live CD.

Re: hwd -e does not list connected USB devices

Additional info:

Tried playing a CD track copied onto the desktop in XMMS.  The display shows it responding in XMMS.  There is no audio from the external USB sound device.

The mixer in KDe is set to USB Audio mixer (PCM).  An output ICON appears but there is no INPUT icon( No source connected).

hwsetup -v -n follows:
.................................................................................................................................
root@n6re ~]# hwsetup -v -n

The hwsetup is Knoppix's / Kudzu detect engine. Hwsetup alone recognizes the port but not the attached device, same as all detect engines. To detect a device requires loading the base modules, what Knoppix automatically does.
For USB with kernel 2.6.x, load modules ohci-hcd and uhci-hcd. It may also require sd_mod.
