URGENT Help Req [Connecting New VPTCL-ZTE in Ubuntu 6.06]

Postby Misam Shah » Tue May 05, 2009 9:46 am

Can any 1 here help me regarding the subjected. I've installed Old VPTCL ZTE set (with a serial to usb cable) to connect internet and working absolutely fine, but now those sets are obsolete and PTCL has launched new ZTE sets which are with usb to usb cable, but it is not being detected by my Ubuntu 6.06.
I am :cry: quite disappointed by this as I'd committed my boss to run internet on Ubuntu using new VPTCL-ZTE set which is just not happening.
Waiting for the solution if anyone has plzzzzzzzz reply.

Best Regards,
Misam Shah

type "tail -f /var/log/kern.log" and then plug the modem's cable in. what do you see?

also, what do "lsusb" say before and after you plug it in?
Watch out for the Manners Taliban!
Isn't it amazing how so many people can type "linuxpakistan.net" into their browsers but not "google.com"?

Unfortunately I've returned that set. Now after a few days I'll get it back. For the time being I've taken some time from my Boss telling him that there are some bugs due to which it is not being detected. :wink:
But the thread is open I'll be back on this in a few days. Thanks for your reply.

Dear Misam Shah,

Check out below link as its for Ubuntu. However you can do same thing for other Linux Distributions.

W/Assalam Linux Freak,
Dear thanks for the link but I've tried that and works successfully for the ZTE serial to USB cable set whereas PTCL has launched new series of ZTE sets which are USB to USB cable. Hope you will have got the issue correctly now.
Please provide if there is any link on new ZTE configuration.

Best Regards,
Misam Shah

Better if you could provide Model. Also if its usb to usb then you can use `lsusb` command to see usb devices on your system.

Recently someone contacted me with a similar problem. The set is ETS 2552. Here are the changes that dmesg reports on connecting the device on Ubuntu 9.04:

Code: Select all

[  245.465216] ISO 9660 Extensions: Microsoft Joliet Level 3
[  245.476182] ISOFS: changing to secondary root

As you can see, it is incorrectly being identified as a CDROM device (/dev/sr1).

On older version of Ubuntu (I think it was 8.10), it showed:

Code: Select all

[  218.562511] usb 2-2: new full speed USB device using uhci_hcd and address 2
[  218.790254] usb 2-2: configuration #1 chosen from 1 choice

And would not create any /dev/ttyUSB0.

I have told him to try on Fedora. May be this time it gets detected correctly.
