SynCE: "Special information for HP iPAQ 5550 owners

Also applies to the MiTAC Mio 168, also known as Bluemedia PDA 255 and Yakumo Delta GPS 300!

The HP iPAQ 5550 and some other newer devices, probably including the HP iPAQ 4150, do not work with any currently existing version of the ipaq module.

The problem is that these devices have more than one pair of USB endpoints. (Compare the output from the usbview program for iPAQ 3970 and iPAQ 5550.)

To fix this, apply ipaq-0.6-olivier.patch (courtesy of Olivier Dugeon), compile the kernel module, and insert it like this:

modprobe ipaq ttyUSB=1

You could also put a line in your /etc/modules.conf or /etc/modprobe.conf file for this:

option ipaq ttyUSB=1

Then configure SynCE to use ttyUSB1 instead of ttyUSB0."

Instead of patching and rebuild the Debian kernel package, I just modified the module ipaq.ko in binary.
