I am not sure that I used usbmon ...,I can't recall it, but I know what
the problem is, I need this patch:
--- drivers/usb/storage/initializers.c.orig 2007-11-17 12:29:25.000000000 +0100
+++ drivers/usb/storage/initializers.c 2007-11-17 12:29:37.000000000 +0100

+ 0x01, 0x0, us->iobuf, 0, 1000);
US_DEBUGP("usb_control_msg performing result is %d\n", result);
return (result ? 0 : -1);
}

With this everything works really smoothly. Even better, now I do get
only 2 (instead of prior 3) /dev/ttyUSB devices (that caused some
problems with umtsmon).

Best wishes
