[Freeswitch-users] USB GSM Dongle with FreeSwitch for voice calls

[Daniel Ivanov]

I also use a hub with external power supply, but that hardly cures the
problem. On a normal x64 system, i seldom get usb errors, but the kernel
doesn't panic. On the Pi i get the same bus or mem errors and it panics to
need restart.
