Actually, with this dongle ZTE MF190, we have 6 TTY (usb0 -> usb5) and 
usb-devices gives:

T:  Bus=02 Lev=02 Prnt=02 Port=00 Cnt=01 Dev#= 32 Spd=480 MxCh= 0
D:  Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
P:  Vendor=19d2 ProdID=0124 Rev=00.00
S:  Manufacturer=ZTE,Incorporated
S:  Product=ZTE WCDMA Technologies MSM
S:  SerialNumber=P671A2TMED010000
C:  #Ifs= 7 Cfg#= 1 Atr=e0 MxPwr=500mA
I:  If#= 0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I:  If#= 1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I:  If#= 2 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I:  If#= 3 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I:  If#= 4 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I:  If#= 5 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
I:  If#= 6 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage

Now, ttyUSB5 is not responsive. So, for this particular dongle, the
modem won't be on the latest interface. In practice, we shall use the 
interface ttyUSB4 for PPP.

Windows Device Manager gives the following results:
Vendor Id: 19d2 / Product Id: 0124 (same as after usb_modeswitch)

ZTE Diagnostic port             - 00
ZTE AT port                 - 01
ZTE ATExt2 port             - 02
ZTE USB SmartCard Reader         - 03
ZTE Proprietary USB Modem         - 04
ZTE Mobile broadband Network manager     - 05

So, it confirms that the modem port com is on ttyUSB4.

To not break the support of ZTE modems with 5 interfaces (which are 
using the 4th one for PPP, like K3570), I can't extend the current logic 
in udevng to take into account the ttyUSB4. So, I added a specific rule 
for ZTE MF190.

Philippe.
