Display USB device configuration
usb [-aDtVv] [-b busno -d devno -N name]
QNX Neutrino
The usb utility displays USB device configuration. As you repeat the number of -v (verbose) options, you'll get more levels of detail.
Here's some sample output from the command usb -vvv. Note that a USB Hub device with an integrated card reader (IOGEAR Model GUH286) is connected in this case.
