Hi all,
I'm using mainline upstream 3.6.0-rc1 compiled based on Fedora-16.

Hi,
I need some help debugging a USB transfer problem on my raspberry pi.
I know this is not a mainstream kernel issue but I would be glad if someone
here can
help me understand and debug the problem.
The problem is that the DVB Transport stream recorded from a usb DVB stick

Convert the request_irq to devm_request_irq.
Also fixes the case where the in the function musb_init_controller
free_irq(called from musb_free) is called before it is allocated.

Have you ever seen this happen? It should not be possible, beca
This driver provides support for several Kvaser CAN/USB devices.
Such kind of devices supports up to three CAN network interfaces.
It has been tested with a Kvaser USB Leaf Light (one network interface)
connected to a pch_can interface.
The firmware version of the Kvaser device was 2.5.205.

Hi,
in finish_port_resume() usb_get_status() is always done and the result
evaluated even in the case of reset_resume. Is this efficient? If a device
has been reset, remote wakeup must be disabled.

Hi all:
I am trying to implement patch of setting DeviceRemovable
according ACPI information.
The DeviceRemovable is set in hcd driver *_hub_descriptor(e.g
ehci_hub_descriptor()). But these
functions just have struct usb_hcd or hcd specific struct(e.g struct xhci_hcd)
and struct

Hi,
I discovered the problem. I am using Openwrt and I was missing the
module usb-serial-option.
Using it everything works fine. The device modules and parameters are
loaded and ttyUSB*
are created.
Thanks for all the help,
Guilherme
