Hi,
Is someone knows how or maybe the caused why my USB 3G dongle doesn't work when plug-in after boot the /dev/ttyUSB*
I wonder how this /dev/ttyUSB1-4 works, i had a 3G USB dongle for my internet connection before i used lucyd lynx this the same USB dongle works fine when i plug-in after boot but now it seems it doesn't after i reformat my laptop lucyd. Now i must plug-in the USB before i boot the machine. After some troubleshooting. i wonder why i don't have the /dev/ttyUSB1-4 when i plug-in after boot.
Is there any configuration that doesn't start when i plug-in when running and it will only start reading it when the USB detected during boot.
I wonder why before its works but now it doesn't..
One time this usb works after i switch from my windows 7 to lucyd.Its like it will work if maybe some packet of data remain in the usb.
I had a maverick on my laptop at home this USB dongle works fine on my maverick 10.10.
Someone knows or maybe solve this issue.
Didn't you already create a topic about this?
You might have better luck in our hardware forum, or in an Ubuntu-specific forum.
I don't know why the /dev/ttyUSB devices don't appear, but it seems more like a symptom than a cause. It may be a kernel-related problem. You might be able to get some information from dmesg, compare what you get when you boot with it plugged in with what you get when you plug it in later. Also see what lsusb tells you, it may give you more specific model numbers etc. to hunt for.
Sorry i already created the topic about this one..i forget since no one address my problem and also i wait for any responce maybe someone knows or solved the problem. Just now i decided to tacke this issue not like before im afraid i will lose my internet connection in the process since this is the only way i can connect to the internet.
By the way i just solved my problem by installing the package usb-modeswitch
Some add info
My USB dongle is HUAWEI E169u, Asus Laptop, and Lucyd lynx. kernel linux 2.6.32-30-generic
Thanks for the reply..
