where is xhci-hcd module in new kernels???

[aa-hcl]

Hi,

After upgrading to 3.2.0-24-generic and 3.2.0-25-generic, I found that my USB3.0 EC card stopped recognizing the hot-plug hard drive.

Looking into the modules I found that the module xhci-hcd is not loaded. It is also not present in the kernel modules:

aa@aa-i7:~$ sudo find / -name *xhci?hcd*
/lib/modules/2.6.38-10-generic/kernel/drivers/usb/host/xhci-hcd.ko
/lib/modules/3.0.0-17-generic/kernel/drivers/usb/host/xhci-hcd.ko
/lib/modules/2.6.38-11-generic/kernel/drivers/usb/host/xhci-hcd.ko
/lib/modules/2.6.38-8-generic/kernel/drivers/usb/host/xhci-hcd.ko
/sys/bus/pci/drivers/xhci_hcd
/sys/module/xhci_hcd
/sys/module/xhci_hcd/drivers/pcihci_hcd
/proc/irq/47/xhci_hcd
/proc/irq/46/xhci_hcd
/proc/irq/45/xhci_hcd
/proc/irq/44/xhci_hcd
/proc/irq/43/xhci_hcd


Does it mean that xhci-hcd is now incorporated somewhere in the kernel?

Initially I was confused: xhci_hcd is a driver and xhci-hcd is a module.

May be for this reason my USB3.0 EC card hot-plug is not working?

Many thanks!!!

I have the same problem. I just bought USB3.0 CF-reader and it doesn't working under Ubuntu 12.04 (Linux 3.2.0-25-generic). This reader works great in Win7.

I didnt checked before, but I also dont have xhci-hcd module

#find / -name *xhci?hcd*
/sys/bus/pci/drivers/xhci_hcd
/sys/module/xhci_hcd
/sys/module/xhci_hcd/drivers/pci:xhci_hcd
/proc/irq/47/xhci_hcd
/proc/irq/46/xhci_hcd
/proc/irq/45/xhci_hcd
/proc/irq/44/xhci_hcd
/proc/irq/43/xhci_hcd
