I know some C, but very little on USB architecture. I'm curious enough
to try, but a bit more direction would be helpful if you can spare some. :)
Also, can you post output from pciconf -lv ?
Sure, and pardon my delay:

BTW, is this behaviour BIOS related? I recently setup another machine
that had Intel's Z77 USB3 controller, and I don't remember having these
issues when attaching the same USB3 device...
Hi,
XHCI is very new, and there might be hardware differences out there.
BTW: The USB 3.0 switching found in Linux is for Pantherpoint only:
See /drivers/usb/host/pci-quirks.c in a recent Linux source code tree:
bool usb_is_intel_switchable_xhci(struct pci_dev *pdev)
{
return pdev-class == PCI_CLASS_SERIAL_USB_XHCI
pdev-vendor == PCI_VENDOR_ID_INTEL
pdev-device == PCI_DEVICE_ID_INTEL_PANTHERPOINT_XHCI;
}
EXPORT_SYMBOL_GPL(usb_is_intel_switchable_xhci);
--HPS
