I have a Samsung Series 9 NP900X4C ultrabook, and since I upgraded to 12.10 and then 13.04, my USB 3.0 ports (two on the right side) don't work anymore after my computer wakes up from suspend mode.

I need to restart my computer to get these two USB 3.0 ports working again.

My USB 2.0 port (one on the left side) doesn't encounter this issue. How do I fix this?

$ cat /sys/bus/usb/devices/*/power/level

I solved it going into the BIOS (F2 key when booting up) and activating "USB S3 Wake_up" option under the Advanced tab. enter image description here

Hope this works for you!
