That is what I said.

That could be the source of my disconnect/reconnect cycles.

I tried your patch with the reverted 0x1 -> 0 change. But it didn't
work. I get connects/reconnects.
So to be clear: kernl 2.6.24-rc3 + your patch gives me permanent cycles
and an error:
option_start_huawei: HUAWEI E220 setup failed (1)
I attach the syslog part which exhibits the behaviour.

the problem.
