Not getting usb 2.0 speeds or port on my system
Hi all,
I am running linux 2.6.27.9-generic kernel on ubuntu. I have 4 ports on the back of my motherboard and 2 on the motherboard itself. All the devices I am running are using 1.1 speeds only and not 2.0.
Here is the output of the devices after changing the ports and rebooting the system.
Code:
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 002: ID 051d:0002 American Power Conversion Uninterruptible Power Supply

and last but not the least.
Code:

Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
This is the output of my /etc/fstab as well.
Code:
$ cat /etc/fstab
# /etc/fstab: static file system information.

I have couple of questions :-
a. As can be seen the Device ID of the 2.0 root hub doesn't change? Why?
b. Is there anyway (any driver or something) that will get me usb 2.0 speeds on all the devices?
