I'd continue to emit a warning in such cases though. It's true that these configurations commonly work, but it's also true they're not _guaranteed_ to work. Another option is just not to configure the device at all, leaving in "config zero" (the default) which is always allowed to consume 100mA. That much current will always be available (except from OTG hosts). - Dave ------------------------------------------------------- SF.Net email is sponsored by: Tell us your software development plans!
