I can just give you a few more ideas to debug this, but that includes more action from your side.

* First of all, try the same device on a different computer, and/or a different USB port, especially if you're using an XHCI (USB3) port.

* Try the device on Mac OS X, without installing a driver and see if you have the same problem here.

* Use usbmon and analyze the data stream when a pop occurs. Compare that with settings that don't produce pops. There's good documentation on usbmon in Documentation/usb/ in the Linux kernel.
