Solaris: How to Reset a USB Device

If a USB device behaves erratically.
Use the cfgadm command to reset the device,
which logically removes and re-creates the device.

1. Become superuser.

2. Make sure that the device is not in use.

3. Reset the device.

For example:

# cfgadm -x usb_reset -y usb0/4.7

4. Verify that the device is connected.

For example:

# cfgadm usb0/4.7

Ap_Id                  Type         Receptacle   Occupant     Condition
usb0/4.7               usb-storage  connected    configured   ok
