Bus 004 Device 002: ID 0ac8 : 305b Z-star Microelectronic Co.

Bus 003 Device 001: ID 0000 : 0000

Bus 001 Device 002: ID 069A : 0311 Askey Computer Corp.
Bus 001 Device 001: ID 0000 : 0000

When I write :

Usb_id ---->>>> No device specified

when I write :

Usbmodules --->>>> You must specify a device with something like :
usbmodules --device /proc/bus/usb/001/003
or
usbmodules -- product 82d/100/100 --type/0/0/0 --interface 0/0/

and I tried usbmodeles --device /proc/bus/001/002 ( Because in lsusb list My modem Askey was in bus 001  device 002 ) it wrote to me as a result : usbnet

what do all those about mean ?
thank you for read...
