There's something very wrong with /dev/ttyUSB4 in recent kernels: unsolicited incoming data from the modem are getting lost; I believe it means also SMS notifications, but it is very easy to reproduce with incoming call notifications. They just don't come. But if you keep pasting "AT" into minicom, they actually do. Of course... that means that trying to debug ofono is ... "interesting". I tried playing with /sys/bus/platform/drivers/phy-mapphone-mdm6600/usb-phy\@1/power/control files and timeouts, but could not get it to work. Any idea what could be wrong there? Is there easy way to disable power management for testing?
