Hi all,
My computer, Sony Vaio T13215, has one usb 2.0 and one usb 3.0.
I created LIVE usb to boot and install, however, if I plugged into usb 3.0, it would install successfully.
but into usb 2.0, it would fail and the message show:

Warning: Could not boot.
/dev/disk/by-label/LIVE
/dev/mapper/live-rw does not exist
...
I have tried on Ubuntu live usb and it happened the same. It means usb 3.0 worked fine but usb 2.0 had not.
Furthermore, I installed Ubuntu via DVD and guest what: it recognized usb 3.0 but usb 2.0 was not working.

I have searched information and some guys happened the same problem with me. And I tried to fix by some guides but It was not successful.

Finally, I am quite sure that the problem is in the kernel.

So, Does someone have suggest?
