><br><br>Steve-<br><br>I had this problem and solved it yesterday with my Dell Latitude d630 running Ubuntu. My symptoms were this: with any USB device plugged in, the system would go into suspend, then immediately come out. Removing the USB device made it stay suspended until I pressed the power button. It sounds to me that your USB ports are getting power properly.<br>
<br>What I did to resolve it was disable all of the USB entries in /proc/acpi/wakeup which allowed the USB device to be plugged in while suspended. I then enabled the USB entries one by one until the USB device brought the PC out of suspend properly. To toggle the entries in this file, just do the following (as root): echo USBX > /proc/acpi/wakeup (where X is one of the USB IDs in the file)<br>
