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. Best regards, Daniel -- Sent from my Android phone with K-9 Mail.
