A couple months ago, I started on a tool to automatically test and enable automatic power management for USB devices. The USB Power Management tool (USB PM tool) is now mostly complete, and is available for download: git clone git://git.moblin.org/usb-pm-tool.git I would love for people to start testing USB devices with this tool. I haven't yet found any devices that can't handle selective suspend, so I really need testers with broken USB devices. If you run the tool and test a couple devices, please send me these two files: /etc/usb-pm-tool/pm-enabled-devices.txt /etc/usb-pm-tool/pm-broken-devices.txt About the tool: ============== The script usb-pm-tool.sh will present the user with a list of devices on their system that are capable of auto-suspend. The user picks a device to test, follows the prompts on the screen, and reports whether the device works successfully after the auto-suspend test. If the device passes the test, the script will prompt the user if they always want to enable auto-suspend for this device. If so, the script will generate a udev rule to enable auto-suspend for the device whenever it is plugged in. Enabling auto-suspend will lower system power consumption, but only if *all* the USB devices on the system have auto-suspend enabled. Eventually I want the tool to ask the user if they want to send info about their device to a centralized server. Then people could download the latest list of devices that correctly auto-suspend. That's still work in progress. Thanks for testing!
