Hello Erich/Matthias,

Thanks for your responses.

I do not have the usbdump command on my system. usbconfig gives the following output :

ugen0.1: <OHCI root HUB ATI> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen1.1: <OHCI root HUB ATI> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen2.1: <EHCI root HUB ATI> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE ugen3.1: <OHCI root HUB ATI> at usbus3, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen4.1: <OHCI root HUB ATI> at usbus4, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen5.1: <EHCI root HUB ATI> at usbus5, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE ugen6.1: <OHCI root HUB ATI> at usbus6, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen0.2: <Back-UPS ES 650Y-IN FW:853.m4.I USB FW:m4 American Power Conversion> at usbus0, cfg=0 md=HOST spd=LOW (1.5Mbps) pwr=ON ugen1.2: <HUAWEI Mobile HUAWEI TECHNOLOGIES> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen2.2: <USB2.0 Hub vendor 0x05e3> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE


PFA ppp.log. As you will find, it repeatedly complains of /dev/cuaU0.0 being an invalid file. But the output of 'ls -l' shows the contrary :

Thanks for any tips/help. Which port do I need to install to get usbdump ?

And my FreeBSD system cannot connect to the internet anymore.

both modems are not officially supported by FreeBSD.

You might get some help from the list if you provide the output of usbconfig 
and usbdump.

You run usbconfig first to find out the device numbers of the modem and then 
dump with usbdump the description of the modem.

Here are the contents of my ppp.conf (I assume authkey means password) :
There should nothing to be done here as the modem is not recognised.
