Hi Johan, Thanks for your answer. That seems a lot like what I am seeing because I had a USB tracer and it showed many NAKed transactions. Regards, Billy. On Wed, Nov 15, 2017 at 2:45 PM, Johan Hovold wrote: > On Wed, Nov 15, 2017 at 12:12:16PM +, Billy Araujo

8k interrupts/sec with USB hub

Hi all, I built a kernel/rootfs for altera SoCkit amd uses the default SoCkit device tree and I plug when in plug in a USB stick it uses the dwc2 driver. When doing cat /proc/interrupts I get normal amount of interrupts - everything seems ok. However, when I connect the USB stick to a USB hub
