I am testing a PCMCIA-based E630 Huawei Turbo3G modem in my TP under
eCS.  Needless to say it does not work but I am looking into solutions
for Linux etc.  Judging from
http://gentoo-wiki.com/HOWTO_Huawei_E630_HSDPA_Data_card, this PCMCIA
card has its own USB controller which the UMTS/HSDPA capabilities are
connected to.  A USB-serial converter is also needed.  My understanding
is that if eCS identifies this USB controller and I have a USB-serial
converter, I should be able to use a PPP program to connect to the
'net.

I also had a very brief opportunity to test an external USB-based
Huawei E220 UTMS/HSDPA modem in the same TP.  Based on the blinking
light, the USB unit seemed to connect to the 3G network and with the
USB driver in my TP.  Too late I discovered a webpage which explained
that any serial communication program can be used to control the modem
whereupon a PPP program is used for the internet connection.

Two questions:
* How can I verify that the PCMCIA E630 modem is properly
identified under eCS and connected and whether the USB stack under eCS
has also identified the card?
* How can verify that the USB stack under eCS has properly
identified and connected with the E220 modem?
* Is a USB-serial driver part of the vanilla USB stack under
eCS?
