I have connected seven different devices to my system. Now I want to know all the bus used by that devices with bus number's and device name.

So how can I do this?

I have used the *lsusb* command. Following is the o/p of that command:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 003: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)
Bus 002 Device 003: ID 0c45:6450 Microdia 
Bus 001 Device 004: ID 413c:8161 Dell Computer Corp. Integrated Keyboard
Bus 001 Device 005: ID 413c:8162 Dell Computer Corp. Integrated Touchpad [Synaptics]
Bus 001 Device 006: ID 413c:8160 Dell Computer Corp. Wireless 365 Bluetooth

In the following output 001, 002, 001, 002,001,002,001,001,001. are the displayed number.

Is it bus number or any thing else?

Also one quick question can we increase USB port bandwidth?
