My USB Keeps disconnecting and reconnecting randomly even though the USB selective suspend is disabled and the "allow the computer to turn this device off to save power" option in the device manager is unchecked as well. I even tried Super-Charger (people who have MSI Laptop might know) and nothing.
This problem occurs when i use an extension cable to get better signal for my HSPA modem.
Btw i should also point out that both USB 2.0 and 3.0 have the same issue.
