If I turn off CONFIG_PCI_REALLOC_ENABLE_AUTO then all my USB devices behave. But with CONFIG_PCI_REALLOC_ENABLE_AUTO=y then some of my USB controllers are broken.
fwiw, you should be able to toggle that on cmd line, as well:
"
[ ] Enable PCI resource re-allocation detection
Symbol: CONFIG_PCI_REALLOC_ENABLE_AUTO
Help: Say Y here if you want the PCI core to detect if PCI resource
re-allocation needs to be enabled. You can always use pci=realloc=on
or pci=realloc=off to override it. Note this feature is a no-op
unless PCI_IOV support is also enabled; in that case it will
automatically re-allocate PCI resources if SR-IOV BARs have not
been allocated by the BIOS.
When in doubt, say N.
"
Thanks for the tip! That indeed works too. I am now running the official Fedora 6.14.2-300.fc42.x86_64 kernel with pci=realloc=off on the cmdline, and all the USB controllers come up.
