https://bugzilla.kernel.org/show_bug.cgi?id=217122 --- Comment #32 from Michael (ZeroBeat@xxxxxx) --- Some additional information: I'm on kernel 6.4.8 and noticed that a WiFi device connected to an USB 3 port doesn't work: Bus 002 Device 003: ID 0e8d:7612 MediaTek Inc.

I don't think that it is a driver problem, because I tested several devices manufactured by different vendors (mt76m rt2800usb). Unfortunately I got no dmesg message like this user https://github.com/ZerBea/hcxdumptool/issues/334#issuecomment-1667093519 I guess all this problems are related to each other. BTW: A long time ago, we got something similar related to XHCI): https://bugzilla.kernel.org/show_bug.cgi?id=202541 but that seems to be fixed, now. -- You may reply to this email to add a comment.
