Problems with USB devices in Ubuntu 10.04 LTS
 

Hi,
I am happy with using Ubuntu 10.04 LTS on my home pc except one issue. Whenever i plug in any USB device like pen drive, hard disk or my nokia c5-03 mobile device, my machine works 5-10 minutes smoothly, but after 5-10 minutes suddenly screen becomes black, some zig-zag messages displays so fast, flickering, some horizontal and vertical lines comes and i am not able to work in. I plug out device, restart, again plug in device. Now after 10-15 minutes same loop. Third time it takes 20-25 minutes. I mean i fear that problem is going to come at time. If i don't use any USB then there is no problem, PC works very smoothly.

I am not getting why this is happening with Ubuntu, while same devices are working fine with windows xp. Kindly help me to resolve issue; or let me know if i am unclear in my problem please.

Regards

Try running this code in a terminal window
 

Run this code in terminal before plugging in the device.

I have no real clue as to why but perhaps something will show here that may lead to something. Hopefully you can see something when it happens. When the screen goes black, can you ctrl+alt+F2 to a new terminal? From there you might be able to read the log or power down gracefully.

When it returns read the syslog for a clue. With this information it might show something. Note the time when inserting the device and it will help pinpoint something in the log.
