Just finished loading Gentoo on a HP Folio13 and the last thing i cant get working is the USB 3.0 support. The kernel has been compiled with the xhci_hcd module and it is active on the controller but there aren't any messages in dmesg whenever i plug in a 3.0 device. One other thing i read about was that legacy mode needed to be enabled for usb3.0 support but this laptop doesn't have any bios options for this, anyone got any ideas?

Code:

gentoo-folio13 linux # cat .config | grep -i xhci
CONFIG_USB_XHCI_HCD=y
CONFIG_USB_XHCI_PCI=y
gentoo-folio13 linux # dmesg | grep -i xhci

Did you ever get this sorted out?

I just installed a Renesas-based 3.0 ExpressCard:

Code:
# lspci -v

...

05:00.0 USB controller: Renesas Technology Corp. uPD720202 USB 3.0 Host Controller (rev 02) (prog-if 30 [XHCI])
        Flags: fast devsel, IRQ 19
        Memory at f4300000 (64-bit, non-prefetchable) [disabled] [size=8K]
        Capabilities: [50] Power Management version 3
        Capabilities: [70] MSI: Enable- Count=1/8 Maskable- 64bit+
        Capabilities: [90] MSI-X: Enable- Count=8 Masked-
        Capabilities: [a0] Express Endpoint, MSI 00
        Capabilities: [100] Advanced Error Reporting
        Capabilities: [150] Latency Tolerance Reporting
        Kernel driver in use: xhci_hcd
...



To activate this, I enabled these kernel options:

Code:
Renesas USBHS controller (USB_RENESAS_USBHS)

CONFIG_USB_RENESAS_USBHS:

Renesas USBHS is a discrete USB host and peripheral controller chip
that supports both full and high speed USB 2.0 data transfers.
It has nine or more configurable endpoints, and endpoint zero.

Say "y" to link the driver statically, or "m" to build a
dynamically linked module called "renesas_usbhs"

Symbol: USB_RENESAS_USBHS [=y]
Type : tristate
Prompt: Renesas USBHS controller
Location:
-> Device Drivers
-> USB support (USB_SUPPORT [=y])
-> Support for Host-side USB (USB [=y])
Defined at drivers/usb/renesas_usbhs/Kconfig:5
Depends on: USB_SUPPORT [=y] && USB [=y] && USB_GADGET [=y] && (ARCH_SHMOBILE || SUPERH || COMPILE_TEST [=y])


Renesas USBHS HCD support (USB_RENESAS_USBHS_HCD)

CONFIG_USB_RENESAS_USBHS_HCD:

The Renesas USBHS is a USB 2.0 host and peripheral controller.

Enable this option if your board has this chip, and you want
to use it as a host controller. If unsure, say N.

To compile this driver as a module, choose M here: the
module will be called renesas-usbhs.

Symbol: USB_RENESAS_USBHS_HCD [=y]
Type : tristate
Prompt: Renesas USBHS HCD support
Location:
-> Device Drivers
-> USB support (USB_SUPPORT [=y])
-> Support for Host-side USB (USB [=y])
Defined at drivers/usb/host/Kconfig:709
Depends on: USB_SUPPORT [=y] && USB [=y] && USB_RENESAS_USBHS [=y]


Renesas USBHS controller (USB_RENESAS_USBHS_UDC)

CONFIG_USB_RENESAS_USBHS_UDC:

Renesas USBHS is a discrete USB host and peripheral controller chip
that supports both full and high speed USB 2.0 data transfers.
It has nine or more configurable endpoints, and endpoint zero.

Say "y" to link the driver statically, or "m" to build a
dynamically linked module called "renesas_usbhs" and force all
gadget drivers to also be dynamically linked.

Symbol: USB_RENESAS_USBHS_UDC [=y]
Type : tristate
Prompt: Renesas USBHS controller
Location:
-> Device Drivers
-> USB support (USB_SUPPORT [=y])
-> USB Gadget Support (USB_GADGET [=y])
-> USB Peripheral Controller
Defined at drivers/usb/gadget/udc/Kconfig:164
Depends on: USB_SUPPORT [=y] && USB_GADGET [=y] && USB_RENESAS_USBHS [=y] && HAS_DMA [=y]


Plus the XHCI driver, of course. These are all statically compiled into the kernel.

I have a couple of observations:


  • When I attach a USB 3.0 external hard disk, it detects it as a USB mass storage device, but doesn't assign a SCSI device to it.
  • Hotplugging the ExpressCard does not really work. After reinsertion the card is detected but the kernel no longer shows a response when a device is attached. I can see the ExpressCard in lspci output and the hard disk in lsusb output, but there is no activity in the syslog.


Any ideas?
