i've tried several suggested solutions none of which work. previous 32 bit ubuntus saw all the ports on my motherboard but no 64 bit ubuntu/debian versions have been able to utilize all the ports. the 4 usb3 ports work but not the 10 usb10 ports. the suggestion to turn iommu on in the bios causes a crash with loss of data. both the bios and windows 10 can use all the ports.

Can you [edit] to add the output of `lsusb -t` to your question?

Please provide some clear Ubuntu product/release details; I'd expect the same results for a 64bit and 32bit release where they are the same release + same kernel stack, but you've given no details. Also please don't hide details in title (*which may not be viewable if using smaller screens/larger fonts*) putting all details in your question.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
