I have a custom TX1 carrier board which I have been developing on, which has an integrated smsc95xx USB hub with a couple devices hard-wired to it. I have been using Jetpack 3.0/L4T24.2.1 for a while now, and the USB hub has always worked fine for me. When I switched to Jetpack 3.1/L4T28.1, my internal USB hub is no longer detected. I can connect an external hub with the same chipset, and it is detected and works, so I know the driver exists in my kernel. For some reason, the internal hub is no longer working with the new Jetpack 3.1
Has anyone noticed any strangeness with USB hubs in Jetpack 3.1?
