http://lists.opensuse.org/opensuse/2007-01/msg00204.html is the PCTEL 2304WT v.92 MDC mailing list thread which lead to my submitting this. This is not my Dell C610/C640 laptop. Its owner entrusted me to solve his problem with W2K no longer recognizing the modem after he randomly deleted various files following failure to connect to his ISP after his ISP's phone numbers went bad. I repartitioned to provide space for SUSE, then installed XP using the Dell custom XP installation CD, which failed to find the modem. After several attempts to install various drivers without success, not knowing that the ISP phone numbers were bad and with the XP driver always failing to make any audible indication that it was doing anything at all. I proceeded to install SUSE 10.0 from the boxed DVD. The modem worked immediately on completion of the 10.0 installation, though I still had no usable connection from the bad phone numbers, so I rebooted XP. Eventually I found the R53654 driver on the Dell web site. Once that was installed I managed to find out about the bad phone numbers, and XP was then able to connect to his ISP. Next I installed OpenSUSE 10.2 from HTTP. The modem failed initial testing, unlike 10.0. I got the 10.2 boxed DVD and tried again, failing in same manner. So, here's the ModemData.txt file. -------------------------- System information ---------------------------- Welcome to openSUSE 10.2 (i586) - Kernel Linux version 2.6.18.2-34-default (geeko@buildhost) (gcc version 4.1.2 20061115 (prerelease) (SUSE Linux)) #1 SMP Mon Nov 27 11:46:27 UTC 2006 scanModem update of: 2006_December_25 USB modem not detected by lsusb Modem or host audio card candidates have firmware information: PCI slot PCI ID SubsystemID Name ---------- --------- --------- -------------- 00:1f.6 8086:2486 134d:4c21 Modem: Intel Corporation 82801CA/CAM AC'97 Modem Controller Modem interrupt assignment and sharing: 5: 404 XT-PIC Intel 82801CA-ICH3, Intel 82801CA-ICH3 Modem --- Bootup diagnositcs for card in PCI slot 00:1f.6 ---- ACPI: PCI Interrupt 0000:00:1f.6[B] -> Link [LNKB] -> GSI 5 (level, low) -> IRQ 5 ACPI: PCI interrupt for device 0000:00:1f.6 disabled PCI: Enabling device 0000:00:1f.6 (0000 -> 0001) ACPI: PCI Interrupt 0000:00:1f.6[B] -> Link [LNKB] -> GSI 5 (level, low) -> IRQ 5 PCI: Setting latency timer of device 0000:00:1f.6 to 64 The PCI slot 00:1f.6 of the modem card may be disabled early in a bootup process, but then enabled later.

Lacking a dsp (digital signal processing) chip, the modem is a software intensive or "softmodem" type. Its primary controller manages the traffic with the CPU.
