Intel 82801BA/BAM USB, Intel 82801BA/BAM AC'97 Audio, and MATSHITA UJDA710 Problems

This is a post to cover several problems I'm having with my hardware after an upgrade from the 2.4.23 kernel to a stock 2.6.1 kernel on Slackware 9.1.


I'm having some odd audio problems. I get good audio feedback from the modem logon proceedure--sometimes. Not always. I'm using a:

00:1f.6 Modem: Intel Corp. Intel 537 [82801BA/BAM AC'97 Modem] (rev 03) (prog-if 00 [Generic])

With the linuxant HSF modem drivers, and a:

00:1f.5 Multimedia audio controller: Intel Corp. 82801BA/BAM AC'97 Audio (rev 03)

With the standard ALSA kernel level drivers. On the occasions when I have no audio feedback from the modem, when I close KDE to kill the workstation, I hear the last three or four seconds of the data transfer--as if that much of the modem's audio feedback were en queue the entire time. I have enabled full duplex in KDE's aRTs sound control server options, but this has not helped.


I'm having some trouble with my CD writer. I have been using SCSI emulation for the 2.4.x release series with no trouble. I recieved the usual notice that Linux now supports direct writing to IDE-CD, which I do not understand. I have had support for the ATAPI protocol in every kernel I've ever used on this computer, but XCDRoast always gives me warnings that the stack protocol is innefficient. I assume this is different than IDE-CD, but I don't know how to impliment this.

ide-scsi is deprecated for cd burning! Use ide-cd and give dev=/dev/hdX as device
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
Vendor: MATSHITA Model: UJDA710 Rev: 1.50
Type: CD-ROM ANSI SCSI revision: 02
Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 5

That is the relevant dmesg output. I know there is no output attaching this to /dev/sr0, which there was in the past. Neither sr0 nor sg0 nor hdc will mount, reporting bad superblocks or claiming that no such device exists. I have tried this with multiple CD's. Mainly, I want to impliment the IDE-CD protocol.


I'm having still and yet more trouble with my USB host adapter. I use the KDE InfoCenter to get a look at what's listed under my USB devices. Most times, my hub (PCI bridge, not an external hub) and two ports are *not* listed. Relevant output:

00:1f.2 USB Controller: Intel Corp. 82801BA/BAM USB (Hub #1) (rev 03) (prog-if 00 [UHCI])

I have UHCI statically compiled into the kernel, I believe, but the UHCI host adapter is not being properly recognized.

Thanks in advance to all who answer,
