I have a Win 8.1 laptop that has USB 3 ports. I'm using a USB DVD/CD RW with it. But it's doing the connect, reconnect, connect, reconnect. Something similar happened with external HDDs, but not this bad.

Tried these links:

Download Windows 8.1 Update for x64-based Systems (KB2919355) from Official Microsoft Download Center

So I did:

(1) In my Power Options, I disabled "Hard Disk Turn-off" and "USB Re-charge power-save thing"

(2) In Device Manager, in HID and USB section, I went to their properties and disabled all the power management.

(3) I tried to install the update[Windows8.1-KB2919355-x64] except, it tells me I already have it installed.

(4) What shall I do?

Thanks.
