Use the cfgadm command to display USB bus information. For example:
% cfgadm Ap_Id Type Receptacle Occupant Condition usb0/4.5 usb-hub connected configured ok usb0/4.5.1 usb-device connected configured ok usb0/4.5.2 usb-printer connected configured ok usb0/4.5.3 usb-mouse connected configured ok usb0/4.5.4 usb-device connected configured ok usb0/4.5.5 usb-storage connected configured ok usb0/4.5.6 usb-communi connected configured ok usb0/4.5.7 unknown empty unconfigured ok usb0/4.6 usb-storage connected configured ok usb0/4.7 usb-storage connected configured ok |
In the preceding example, usb0/4.5.1 identifies a device connected to port 1 of the second-level external hub, which is connected to port 5 of first-level external hub, which is connected to the first USB controller's root hub, port 4.
Use the following cfgadm command to display specific USB device information. For example:
% cfgadm -l -s "cols=ap_id:info" Ap_Id Information usb0/4.5.1 Mfg: Inside Out Networks Product: Edgeport/421 NConfigs: 1 Config: 0 : ... usb0/4.5.2 Mfg: <undef> Product: <undef> NConfigs: 1 Config: 0 ... usb0/4.5.3 Mfg: Mitsumi Product: Apple USB Mouse NConfigs: 1 Config: 0 ... usb0/4.5.4 Mfg: NMB Product: NMB USB KB/PS2 M NConfigs: 1 Config: 0 usb0/4.5.5 Mfg: Hagiwara Sys-Com Product: SmartMedia R/W NConfigs: 1 Config: 0 : ... usb0/4.5.6 Mfg: 3Com Inc. Product: U.S.Robotics 56000 Voice USB Modem NConfigs: 2 ... usb0/4.5.7 usb0/4.6 Mfg: Iomega Product: USB Zip 250 NConfigs: 1 Config: 0 : Default usb0/4.7 Mfg: Iomega Product: USB Zip 100 NConfigs: 1 Config: 0 : Default |
