Public bug reported: [SRU Justification]
[Impact] Cold plugged USB device was not detected on certain PCIe USB cards (like Inateck card connected to AM64 EVM or connected to J7200 EVM). And also the root hub mentioned in https://bugs.launchpad.net/bugs/1939638. Re-plugging the USB device always gets it enumerated. [Fix] Register both root hubs along with the secondary hcd for xhci. [Test Case] 1. Plug the USB device to the ports of problematic root hub. 2. Power on the machine. 3. Check if the USB device can work or not after boot. [Regression Potential] Low. It simply make sure both primary and secondary roothubs are registered along with the second HCD. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Affects: linux (Ubuntu Hirsute) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Hirsute) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945211 Title: Fix cold plugged USB device on certain PCIe USB cards To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1945211/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
