Ubuntu 6.06 does not properly recognize serial to usb modem

[ramnarayan]

Was trying to set up a Huawei FWT CDMA Phone Modem on Ubuntu 6.06

This is the dmesg section relevant to the serial -usb:

> >> [17179585.756000] drivers/usb/serial/usb-serial.c: USB Serial support
> >> registered for pl2303
> >> [17179585.756000] pl2303 3-1:1.0: pl2303 converter detected
> >> [17179585.756000] usb 3-1: pl2303 converter now attached to ttyUSB0
> >> [17179585.756000] usbcore: registered new driver pl2303
> >> [17179585.756000] drivers/usb/serial/pl2303.c: Prolific PL2303 USB to
> >> serial adaptor driver

It did not reflect a successful setup of the modem, which presumable has a Controller chipset.

This was figured out after getting this message from wvdialconf
am@ram:~$ sudo wvdialconf /etc/wvdial.conf

Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?

Am wondering where the issue is - ? with the kernal or with the peripheral

thanks

Does it work on Feisty? I think the later kernels have more support for this.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? (Gutsy at this time). Thanks in advance.

[Craig Maloney (craig-decafbad)]

Just wanted to check, since Hardy Heron was recently released, if you've had a chance to check the USB serial modem with Hardy, and if it's working or not working.

Thanks!

Marking as invalid as there doesn't appear to be any activity on this bug. If you are still having issues with this modem under Hardy, please either reopen this ticket by changing the status to New, or open a new bug report. Thanks!

Hi Craig

First sorry for the delayed reply

But the Serial to USB modem works under 7.04 and 7.10 (i think) but
definitely not under 8.04 (hardy). So am reopening the bug.

Ok how it works under 7.04 is that i have been making a rules file under

/etc/udev/rules.d

the file is called
026_ti_usb_3410.rules

with the following contents
#TI USB 3410

SUBSYSTEM=="usb_device" ACTION=="add"
SYSFS{idVendor}=="0451",SYSFS{idProduct}=="3410" \

SYSFS{bNumConfigurations}=="2" \

SYSFS{bConfigurationValue}=="1" \

RUN+="/bin/sh -c 'echo 2 > /sys%p/device/bConfigurationValue'"

***
doing this make the OS attach the serial to USB modem to /dev/ttyusb0 and my
wvdial work.

I upgraded to 7.10 and this continued to work

but i tried to make the same work under 8.04 and this same process does
not work. Am not sure if its an 8.04 problem only or if a tweak is required
somewhere.

So right now i am back at 7.04 and accessing the internet on the FWT

thanks

my wvdial file looks like this

Modem = /dev/ttyUSB0
Baud = 230400
Phone = #777
Init1 = ATZ
Stupid Mode = 1
Dial Command = ATDT
Username = XXXX
Password = xxxxx
PPPD Options = crtcts multilink usepeerdns lock defaultroute

Hi Ram,

I think this is a new issue, so I'm recommending we close this issue (mark it as invalid) for now. Please open up a separate issue, and file it under udev, as it seems your issue is now with the udev rules rather than with kernel support for your modem.

Please let me know if you have any questions.

Thanks!
