USB 3

[nomko]

Till I figured out it had some protective film on the edge connector... :

;D ;D ;D ;D Did it had a label attached to it saying Peel off before installation???

I have a usb 3  addon card and it doesn't show up in LL....Is usb 3 supported?

As an extra addition to the answers of Wirezfree. A USB device can be recognized as following (using your problem to identify USB 3.0)

Bus ***    Device ***:    ID xxxx:yyyy    Linux Foundation 3.0 root hub


So if you enter one of the mentioned terminal commands, look for a value similar as i proved. If you see a line ending with Linux Foundation 3.0 root hub then you now you have USB 3.0 support.

Linux started supporting USB 3.0 since kernel version 2.6.31, released in 2009.
