I have changed my OS from windows XP to ubuntu and all USB devices (USB hdd, flash disk, usb webcam and others) are not noticed. All these devices were fully functional on my computer when I had windows xp. Can you help me please?
The USB bug is actually a HW issue, as I get it in both Windows and Lubuntu. Turns out that shutting down (if you can, my system freezes up and REISUB doesn't work) and then disconnecting Power to the Power Supply for a few minutes fixes the problem.
Here's a thread where I found the workaround: SOLVED USB 2/3 device descriptor read64, error -110
Open a Terminal and issue the command:
As a new user the devices may be recognized, but you don't realize it.
To test the webcam, I like the Cheese application.
If it is not installed, from the terminal you can issue the command:
The cheese application will then be available for your usage.
A valuable command for new users is:
Issue the above command in a terminal and then plug in a usb device. The output is the system recognizing the device and will give you insight into how Linux 'sees' those devices.
