Frida fails to work on more than one iOS device via usbfluxd

[Manouchehri]

usbfluxd is a handy little application to make remote iOS devices appear as if they work local. For some reason though, Frida is only able to use the first device. Not sure if this is a usbfluxd or Frida bug.

MacBook-Air:~ dave$ frida-ls-devices
Id                         Type    Name
-------------------------  ------  ------------
local                      local   Local System
00008030-000009CB5CA0304A  usb     iPhone
socket                     remote  Local Socket

This is from the remote server:

dave@mini ~ % sudo /Applications/USBFlux.app/Contents/Resources/usbfluxd -f --no-mdns
...
[18:25:38.456][4] New client on fd 6
[18:25:38.457][1] Client 6 command received in the wrong state
[18:25:38.457][4] Disconnecting client 0x7fd61940ae00 fd 6

idevice_id -l is able to discover both iPhones though!
