I'm using Ubuntu 13.04 Gnome edition. I have a problem with my Arduino Duemilanove Board. Previously I was using kernel 3.9.2-030902-generic. After I installed kernel 3.10rc6 and I start my arduino IDE I didn't see a serial port /dev/ttyusb0 as before for uploading my code onto the board, Now there is only one /dev/ttyS0. I tried plugging my board in all the usb port but none of them helped in uploading via /dev/ttyS0. I don't know it's actually because of kernel 3.10 but previously everything was working fine. This is the link to lsusb and dmesg command output after plugging the board.
I finally removed the kernel 3.10 and made the kernel 3.9.2 default. The dmesg remains the same and does show some error in the last lines I tried google out the error but didn't find solution.
