Verizon V620 Working In Ubuntu Breezy

---

This is how I got my Verizon V620 Partially Working.
I'm dual booting and When running in WinXP it connects quite a bit faster so I'm still trying to get some better speeds. It looks like the patch talked about earlier is my best bet.

Running: Ubuntu Breezy on a Dell XPS Gen2 Laptop

DISCLAIMER, I'm not an expert but these are a compilation of the steps I took after scouring the internet. They may or may not work for you.


STEP 1)

I used Sipple's technique to get my system to recognize the device:

modprobe -r usbserial
modprobe -r ehci-hcd
modprobe -r ohci-hcd
modprobe ohci-hcd
modprobe usbserial vendor=0x1410 product=0x1110

My card is now located at /dev/ttyUSB0

STEP 2)

under /etc/ppp/peers/ I created a file called evdo

----- EVDO -----
nodetach
ttyUSB0
230400
ipparam rtt
noauth
defaultroute
usepeerdns
user 5554443333@vzw3g.com
password vxw
show-password
crtscts
lcp-echo-interval 9999
lock
connect-delay 10000
connect '/usr/sbin/chat -v -t3 -f /etc/ppp/peers/1xevdo_chat'
----- END EVDO ----

(Obviously change "user5554443333" to whatever your modem's number is.)

STEP 3)

Under /etc/ppp/peers I created a file called 1xevdo_chat

------- 1xevdo_chat -------

'' 'AT'
'OK' 'ATE0V1&F&D2&C1S0=0'
'OK' 'ATDT#777'

--------- END 1xevdo_chat ------

STEP 4)
to connect type this at the prompt "sudo pppd call evdo"

This works but there is still something wrong when I try to download. It will start with
a realitivly high speed then stall out in a matter of seconds. - I'm still working on this

I hope this information is useful to someone!
