Your memory is wrong. I wrote a patch which will enable libusb to scan the existing buses and devices without wakening them all up. But libusb has to be changed to take advantage of this, and that change hasn't been written. Note: This is libusb, not lsusb. > Will it fix this issue? No. Even if libusb were changed, it wouldn't help lsusb -- lsusb still would have to wake up a device in order to read its descriptors.
