Have a look at how "lsusb" fetches port status from hubs... Notice by the way that "overcurrent condition" is a hardware report, but the messages you showed were software warnings about exceeding the power budget. Those are two different things. You can compute the power budget following the rules in the USB spec and the current device configuration as shown in sysfs ... except for the case of root hubs that have nondefault power budgets (less than 500 mA per port). - Dave ------------------------------------------------------- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?
