Is there a fix for this?
These resets are generally the result of low-level device or communication problems. Check the quality of your cables (including any cables which may connect the USB ports to the motherboard on the inside of the computer case). If you want to get more information about what's going wrong, start by turning on CONFIG_USB_SUSPEND and see what dmesg shows. To get even more info, use the usbmon facility (instructions in the kernel source file Documentation/usb/usbmon.txt).
