CPU=i686,  pclinuxos Linux release 2006 (Texstar) for i586
Kernel 2.6.16.27.tex1.lve on an i686 / 
Linux version 2.6.16.27.tex1.lve (ocilent1@xpc) (gcc version 3.3.1 (Mandrake

 scanModem update of:  2007_Feb_10


USB modem not detected by lsusb

Modem or host audio card candidates have firmware information:

 PCI slot	PCI ID		SubsystemID	Name
 ----------	---------	---------	--------------
 00:0d.0	1813:4000		Communication controller: Ambient Technologies Inc HaM 
controllerless modem 

 Modem interrupt assignment and sharing: 

 --- Bootup diagnositcs for card in PCI slot 00:0d.0 ----

 === Finished modem firmware and bootup diagnostics section. ===
 === Next deducing cogent software ===

===================================
 The modem interrupt (IRQ) is 255 . IRQs of 0 or 255 are not functional!! 
 The CPU cannot control the modem until this situation is corrected!!
 Possible corrections are:
   1) Within the boot up BIOS, change from a Windows to a non-PNP/Other 
Operating System type.
   Instructions for accessing BIOS are at:
      http://linmodems.technion.ac.il/resources.html within:  Additional 
Resourcces.
   2a) Add an option "pci=routeirq" to the kernel boot up line.
      Here is an example paragraph from  /boot/grub/menu.lst :
	title           Ubuntu, kernel 2.6.15-26-686
	root            (hd0,6)
	kernel          /boot/vmlinuz-2.6.15-26-686 root=/dev/hda7 ro pci=routeirq
	initrd          /boot/initrd.img-2.6.15-26-686
	savedefault
   2b) Same as above, but use "pollirq" instead of "pci=routeirq". 
   3) Within some BIOS setups, IRQ assignments can be changed.
   4) On non-laptop systems, moving the modem card to another slot has helped.
   5) Sometimes upgrading the kernel changes IRQ assignment.
=====================================

PCIbus=00:0d.0
00:0d.0 Communication controller: Ambient Technologies Inc HaM controllerless

	Flags: medium devsel, IRQ 255
	Memory at ef005000 (32-bit, non-prefetchable) [size=4K]
	I/O ports at e400 [size=256]
	Capabilities: [60] Power Management version 2

 For candidate modem in PCI bus:  00:0d.0
   Class 0780: 1813:4000 Communication controller: Ambient Technologies Inc 
HaM controllerless modem
      Primary PCI_id  1813:4000
 Support type needed or chipset:	AmbientTech
 Under Linux 2.6.n kernels, the chipset is NOT SUPPORTED . Read 
InfoGeneral.txt about alternatives.


 Vendor=1813 Ambient Tech was acquired by Intel with its HaM (Host assisted 
Modem) chipsets.
 There is no support under 2.6.n kernels!!
 Intel-v92ham-453.tgz 2.4.n kernels was the FINAL 2.4.n update for HaM modems, 
available at:
    http://linmodems.technion.ac.il/packages/Intel/ham/ 
    http://developer.intel.com/design/modems/support/drivers.htm
    It is NOT functional when compiled under 2.6.n kernels.
 But under the 2.4.nn kernels, all HaM chipsets were supported,
    with a single EXCEPTION: the odd PCI_ID 1813:4100 modems.  For the 
explanation, see message:
    
http://linmodems.org/cgi-bin/ezmlm-cgi?1:mss:9448:200210:fbhcoigfcimgkjdedjad
 ====== end AmbientTech section =======


 Completed candidate modem analyses.

 The base of the UDEV device file system is: /dev/.udevdb

 Versions adequately match for the compiler installed: 3.3.1
             and the compiler used in kernel assembly: 3.3.1


 
 Compiling resources appear complete:
   make utility - /usr/bin/make
   Compiler version 3.3
   kernel_headers base folder /lib/modules/2.6.16.27.tex1.lve/build


Checking pppd properties:
	-rwsr-xr-t  1 root root 300248 Jul 23  2006 /usr/sbin/pppd

In case of an "error 17" "serial loopback" problem, see:
    http://phep2.technion.ac.il/linmodems/archive-sixth/msg02637.html

To enable dialout without Root permission do:
	$ su - root  (not for Ubuntu)
         chmod a+x /usr/sbin/pppd
or under Ubuntu related Linuxes
	 chmod a+x /usr/sbin/pppd

Checking settings of:	/etc/ppp/options
lock
noauth
noipdefault
usepeerdns

In case of a message like:
   Warning: Could not modify /etc/ppp/pap-secrets: Permission denied
see http://linmodems.technion.ac.il/bigarch/archive-sixth/msg04656.html

Read Modem/YourSystem.txt concerning other COMM channels: eth0
Which can interfere with Browser naviagation.

 Don't worry about the following, it is for the experts
 should trouble shooting be necessary.
