[Synce-devel] SynCE kernel driver and MPx220 smartphone

Hello,
I'm trying to connect my Motorola MPx220 smartphone (WM2003 SE) with Gentoo (2.6.21-gentoo-r3) and I've got a few problems.

The ipaq driver from synce svn does not compile with my kernel as there is no "max_flip_cnt" variable in tty struct in kernels >2.6.17.
I tryied to solved this by using this part of code from the 2.6.21 kernel driver:
if (tty && urb->actual_length) {
tty_buffer_request_room(tty, urb->actual_length);
tty_insert_flip_string(tty, data, urb->actual_length);
tty_flip_buffer_push(tty);
bytes_in += urb->actual_length;
}

Now it compiles but it does the same as the kernel driver from 2.6.21.
With both drivers I get this:

in dmesg:
/home/koprajs/kernel-2.6-driver/ipaq.c: ipaq_read_bulk_callback - nonzero read bulk status received: -2

in /proc/bus/usb/devices:

E: Ad=03(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms

If I try insmod ./ipaq.ko ttyUSB=1 with the SynCE driver I get unhandled kernel null pointer error.

Any suggestions? I've seen some /proc/bus/usb/devices from other users with MPx220 and it seems there are at least 3 diffrent versions (maybe caused by diffrent ROMs?). Does that mean that my phone is not supported by the ipaq driver yet? Or is there a problem with the newer kernels?

Thank you for any help.

I suggest that all MPx220 owners get together and do some kernel
hacking! :-)

SynCE development nowadays (if any) concerns Windows Mobile 2005 and
newer, so you can unfortunately not expect any improvements to the ipaq
module... :-(

Hello,
Edit your current kernel's /usr/src/linux/drivers/usb/serial/ipaq.c, find the "static int ipaq_startup(struct usb_serial *serial)" function (line 932 in 2.6.21 kernel) and replace the "return usb_reset_configuration (serial->dev);" with "return 0;".
That's it, now recompile the module and it should work with MS smartphones 2003 including MPx220.

I thought that should have been removed from the kernel? Oh well, nice
catch! :-)

You can download already patched version of ipaq.c from attachment. It's for 2.6.21 but should work with newer kernel's too.
Enjoy, KOPRajs :-)
