Once upon a time, fedora@xxxxxxxxxxxxxx <fedora@xxxxxxxxxxxxxx> said: > I think I figured it. The USB cables I have are all providing only minimal connectivity, so only USB2 speed. This is how a lot of "charging" cables work - they might be able to pass 100W (or more) in power delivery mode, but only USB2 data signals. New cables/adapters/etc. are all supposed to be marked with the data rate and power delivery supported. For example, my recent cable purchases have 10G/100W and 40G/240W marked. But there's no telling with previous cables other than to plug them in with a variety of devices and see what you get. The data speeds are also confusing because of marketing... there's "USB 3.0" which does 5G (but was then retroactively renamed "USB 3.1 Gen 1" and then "USB 3.2 Gen 1x1"). "USB 3.1 Gen 2" (aka "USB 3.2 Gen 2x1") is 10G, and "USB 3.2 Gen 2x2" is 20G. And then "USB4" (no space) gets even more modes and names. Their next renaming attempt is to stop all the version games and go with speeds (like they should have done from the start), so "USB 5Gbps", "USB 10Gbps", "USB 20Gbps", and so on. -- Chris Adams <linux@xxxxxxxxxxx> -- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
