Bug ID: 258839
Summary: ure(4) needs a detach/reattch to work on SUPER
Product: Base System
Version: CURRENT
Hardware: arm64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: usb

Hi,
I had this USB dongle for a long time on a single direct XHCI root port and it
came up with 480 speed and worked without issues (the HIGH speed only is
another issue on that port).
For debugging other things I moved it to a USB3 HUB port attached to a 2nd (but
same dwc3 xhci root) port and ther eit comes up as SUPER speed but after very
little use it has a hiccup.
When running ifconfig then it slightly hangs and then reports a media status of
100 half (the addresses are printed so I assume that query takes time).
It will no longer pass packets at that point.
Doing an ue0 down up will (a) cause the driver to detach and re-attach, and (b)
after it comes back up again it seems to work flawlessly.
I have yet to take usb traces but in case it sounds familar to anyone..
I cannot rule out that it is something specific to the roots/hub currently
but I wanted to document the status quo before I start messing around more.
