Sorry for the long delay (who connects his phone that often?).

Nobody is likely to be able to help you unless you provide more detail. Why can you "no longer use this method"? What happens when you try? Why do you have to reboot? What other recovery techniques (short of rebooting) have you tried?
It simply hangs on next connect attempts. I don't remember finding anything funny on the log or dmesg. I will be happy to assist. Just give me what you want me to check.

I tried it also on my Gentoo installation (currently kernel
2.6.27-gentoo-r8 and also tried it with two different Motorola phones.
I have this problem for more than a year (obviously it is not something I do very often) and I have been waiting patiently hoping (it sure looks like) a kernel upgrade would resolve this problem.

If it is not a kernel problem then you will be waiting forever.

If connection fails with a different phone and a new process and it is not kernel/driver than I don't know what it is. I would assume that a device would become ready once a new process and new HW gets connected to it. But that's me.
