Those folks are actually chomping at the bit to be taken seriously and have been for a very long time! Their proposition is simple: better tools can make us better developers. No wonder Windows BSODd when Gates first demoed USB on stage. I did, of course, peek at the spec and experienced the bone-shuddering realization of how complex this whole system is. All of the externally available USB ports (3x USB 3 ports, 1x USB 2 port, 1x Thunderbolt port) all result in connectivity to the USB 2 root hub.Įvery fiber in my being wants to work out wtf is happening here but I’m resisting because fortunately we have a vendor that can replace this NUC with one from 2016 instead of this one from 2018. One of the chips is only available via an internal header on the board. For reasons unknown, the two controller chips on this NUC present as four controller chips each chip presents as one USB 2 root hub and one 3 root hub. So I go a bit deeper: the chip is actually a thunderbolt chip (aka USB 4.0), which is able to emulate all of the USB specs. No such issues under Windows but we’re not deploying that to the field. Under closer inspection it seems the USB 3.2 Gen 2 port on this relatively modern Intel NUC is being identified by the kernel as being USB 2.0. Too soon! I’m currently debugging an issue where a USB 3.2 Gen 2 scientific camera is unable to negotiate a connection with Linux.
