Novatel Merlin V620 CDMA PC Card: How To?

tempire · 09-17-2005, 05:13 PM

As an addendum to my last message, I am assuming the "usb.c: USB device 2 (vend/prod 0x1410/0x1110) is not claimed by any active driver." message is the cause of no 'usb' folder in /proc/bus.

All I have is:

unconfigured:~# ls -Fals /proc/bus
total 0
0 dr-xr-xr-x 4 root root 0 Jan 1 12:38 ./
0 dr-xr-xr-x 33 root root 0 Jan 1 12:36 ../

Did you manually load the usbserial driver with the correct vendor/product numbers? What do you get when you do the following:

rmmod usbserial
modprobe usbserial vendor=0x1416 product=0x1110

If you do "lsmod", so you see usbserial loaded? If so, then check for the devices in the /dev directory. If they are present, then you are good to go for basic connectivity. You do not need to make the driver changes shown in this thread to get a basic PPP session going.

It looks like my problem had to do with a PCMCIA USB adapter. When I remove the card, it works fine, albiet expectedly dropping the connection after several minutes.

Though I cannot figure out why I have no /proc/bus/usb, in this case I guess it doesn't matter.

Question: anyone know what the Kyocera's vendor and product IDs are? Are they also 1410 and 1110, like the Novatel?

KPC650 is

Vendor=0x0c88
Product=0x17da

I'm having the same trouble with the Kyocera KPC650. Pings forever, load connection dies although PPPD show a connection but no traffic is passing.

I'm not having any luck patching the driver/kernel. I can't seem to get the source tree correct.

I'm using Pebble (debian) and 2.4.26 kernel. Seem to continue to have kernel version issues. I have a Debian 2.4.27 workstation where I'm doing the development.

Can someone post my detailed instructions about the Junxion patch (or equivilent) is applied? ie: kernel source, dependent libraries, patching and make

I was having a lot of drops before I applied this patch, major thanks to Junxion for finding this issue.

For reference, here is the Fedora Core 4 2.6.13-1.1526 kernel version of the patch that georgecmu suggested:

Has anyone experienced the card disconnecting usb the immediately reconnecting? However when this happens the ppp connection still shows connected? But the connection isn't really up.

I managed to get the Novatel V620 working with Ubuntu Linux 5.10. Nothing terribly new or surprising there, except that, like Fedora, the /dev/ttyUSB0 and /dev/ttyUSB1 devices aren't already present, so you have to create them.

I used GNOME PPP as a dialer, and that seemed to work (after editing the /etc/ppp/options file to comment out the LCP lines). GNOME PPP is in either the "Universe" or "Multiverse" Ubuntu collection.

I did have to recompile the usb-serial.c driver code with the aforementioned fix to the buffer_size.

Been reading and re-reading this thread and I've finally gotten really close.

Using the Sprint PCS version of the Merlin the S620 with Ubuntu Breezy.

When I use wvdial, this is what I get: (main bit's at the bottom...I've got IP addresses showing up!!!)

output --------------------------------------------------------
root@rhino:/home/mark# wvdial

MY PROBLEM: I cannot surf the web with firefox. I am able to ping the local IP address and the remote IP address, but I *cannot* ping either primary or secondary DNS. Thus I can't use the internet.

What little tiny step am I missing to make it all come together???? I can see the IPs, but can't reach them. Oooohhhh so close! and after two straight nights messing with this to get it to work.

Thanks,
Mark

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!

Chris

hxmiller · 10-31-2005, 09:51 PM

The error that the usbserial driver reports immediately before disconnecting is:

generic_read_bulk_callback - nonzero read bulk status received: -110.

What could be causing this?

mattengland · 12-11-2005, 10:31 AM

Any followup on malacandra's problems above?

Also, I'm interested in running a WinXP VMware guest OS (on a VMware Workstation 5.0/5.5 Linux host, probably a Debian-based one like Ubuntu...all running on a IBM/Lenovo Thinkpad flavor T42 or T43) as a "backup" in case my V620 does not work natively on my Linux OS. Does anyone have experience with this config working?

-Matt

bhomass · 02-04-2006, 07:12 PM

when I try the v620 on windows, I got over 4 mbps. why is it no one got better than 200-300 kbps on linux? anyone have any idea how to realize more of the speed potential of this card?

ravingvegetable · 02-16-2006, 02:40 PM

hey guys,
I've got a Thinkpad T42, Suse 10, and an activated Sprint S620. I've read thru the thread and the links, and the Verizon stuff does not seem to apply. Anyone with the Sprint card wanna take the time to help ?

I can see it when I do a cat /proc/bus/usb/devices
I manually edited the wvdial.conf
when I run wvdial, I get:
Cannot open /dev/ttyUSB0: Cannot get information for serial port

kindly head this lost soul in the right direction...
Thanks !
