Antonio, >From intel-536-537/makefile_537, PCIDEV=8086:1080 well corresponds to a 537EP modem absolutely handled by the http://vouters.dyndns.org/Intel/intel-536EP-537EP_2010_01_06.tar.bz2 What brings an uncertainty between 536EP and 537SP is PCIDEV=8086:1040 Now Chris is facing a problem with his 537EP modem in modem_init (see kernel stack trace). There is not much I can do to help as the code involved resides in 537_core.lib which has always been Intel's proprietary code and shipped in binary format. This is all the problem with Winmodems. Regards, -- sip:Vouters.Philippe@xxxxxxxxx IM: philvout (Yahoo!) http://vouters.dyndns.org/ Philippe Vouters (Fontainebleau/France) -------- Message initial -------- De: Antonio Olivares <olivares14031@xxxxxxxxx> À: Chris Tracy <chris.t.tracy@xxxxxxxxx> Cc: discuss@xxxxxxxxxxxxx, Marvin Stodolsky <marvin.stodolsky@xxxxxxxxx>, Philippe Vouters <Philippe.Vouters@xxxxxxxxxxx> Sujet: Re: Intel 537EP - driver loads but cannot use modem Date: Sun, 7 Mar 2010 19:44:49 +0000 Chris, It seems to me that this Modem is not really an Intel 537 Modem, but one disguised as one. Here's another user having difficulties: http://ubuntuforums.org/showthread.php?t=1183881 I run scanModem fake the PCI IDS you have sent and it reports Intel 537: === Finished firmware and bootup diagnostics, next deducing cogent software. === Predictive diagnostics for card in bus fake: Modem chipset detected on NAME="FakeName" CLASS=FakeClass PCIDEV=8086:1080 SUBSYS=1028:1000 IRQ=fake IDENT=INTEL537EP For candidate modem in: fake FakeClass FakeName Primary device ID: 8086:1080 Support type needed or chipset: INTEL537EP Since 2006, Intel appears to have ceased its modem code updates for Linux. The outdated official Intel support packages can be accessed through: http://developer.intel.com/design/modems/support/drivers.htm Beneficially, Philippe Vouters has been provided updates as the Linux kernel evolves. But intensive personal support is not feasible, see: http://archives.linmodems.org/24939 The code for the INTEL537 and INTEL536 chipset modems is now at: http://vouters.dyndns.org/Intel/ , previously http://x9000.fr Copies are also stored at: http://linmodems.technion.ac.il/packages/intel/Philippe.Vouters/ For Ubuntu Linux users with Intel 536 and 537 chipsets, there are driver installation packages available thru http://groups.google.com/group/ubuntu-modems Read DOCs/Intel.txt and Modem/DOCs/YourSystem.txt for follow through guidance. Which is a bit different from what you have sent: NAME="Modem: Intel Corporation FA82537EP 56K V.92 Data/Fax Modem PCI " When I see "FA82537EP 56K ", I have seen reports that sadly this modem is unsupported. Marv and/or Phillppe can confirm this, hope that they can let you know if this is sadly true.
