Kernel config files

After upgrading to 6.12.11 from kernel 6.11.11 some USB devices fail to show up.

With 6.11.11 lsusb output is:

Quoted 9 lines

While with 6.12.11 it is:

Quoted 5 lines

I have also attached kernel config files.

I tried to find USB related patches but got lost in git logs. Hopefully somebody more experienced can find the reason for this problem.

--- Comment #1 from Michał Pecio ([email protected]) --- It looks like one of two USB 3.0 controllers disappeared.

If it's Renesas, enabling CONFIG_USB_XHCI_PCI_RENESAS should bring it back.

If not, please post dmesg from 6.12 boot. There should be some xHCI error message there.

Thank you Michał, you nailed it!

Not a kernel bug but a setting error. I copied the kernel config from 6.11 and the Renesas config option was disabled by default. I'm now a happy user of 6.12 :)

--- Comment #4 from Mitchell Rosenbaum ([email protected]) --- You should check in a build between these two and report whether the devices are present or missing, repeating the process until you find the single buggy commit. If Bisect is not possible, you should provide detailed dmesg output from both the working 6.11.11 boot version and the buggy 6.12.11 boot version.

This issue was cleared by adding the proper setting for 6.12.11 kernel config. It has RESOLVED ANSWERED status.

--- Comment #6 from Michał Pecio ([email protected]) --- It was a spammer, no need to respond.

And for the record, this issue has been fixed and CONFIG_USB_XHCI_PCI_RENESAS is no longer required for all Renesas controllers, only for those which really don't have firmware flash connected to them and must be loaded by software. In this regard, recent v6.12.y and later releases should behave like v6.11 or older.
