Good info on Zune USB charging: http://www.zune.net/en-ca/support/usersguide/yourzune/batteryfaq.htm:
USB Battery charging spec: http://www.usb.org/developers/devclass_docs/batt_charging_1_0.zip This (from spec) seems to indicate that a USB device that is plugged-in may not charge if it cannot be connected (meaning recognized by the host): "A device with a dead, weak or no battery is allowed to draw up to 100mA max for up to TUNIT_ISUSP after starting to draw more than 2.5mA, in order to determine if it will be able to connect. If the device determines that it will not be able to connect, then the device is required to reduce its current draw to 2.5mA average after TUNIT_ISUSP." Changes in O/S like Ubuntu which implements USB spec (which also changes with time) may explain why it worked at one point in time and doesn't anymore. Zune is not (natively) supported by Linux or Unix. It contains proprietary protocols by design to only work with Microsoft O/S. There are many posts on the net regarding this issue and some claim they have found workarounds. The list of Ubuntu supported hardware can be found here: https://help.ubuntu.com/community/PortableDevices Is this still an issue for you? If so, still a problem on Intrepid? Any of the above comments helped? I'll mark the bug report as Incomplete until you get back with the answers.
