There are device attached to this hub, but none in use. Is it possible to "reset" the hub and all downstream devices, hopefully to be re-scanned, recognized and re-attached? (It looks like "usbconfig" might be the right tool ... but the documentation has no examples and I don't want to make things worse.) Respectfully, Robert Huff
