Hi,
This patch set introduces 3 helpers for handling usb read, write
and write_async command, and replaces the low level's implemention
with the generic ones.
Firstly, it is a cleanup and about 300 lines code can be saved.
Secondly, the patch fixes DMA on the buffer which is embedded inside
one
This patch introduces the below 3 usb command helpers:
usbnet_read_cmd / usbnet_write_cmd / usbnet_write_cmd_async
so that each low level driver doesn't need to implement them
by itself, and the dma buffer allocation for usb transfer and
runtime PM things can be handled just in one

This patche gets the runtime PM reference count before calling
usb_control_msg, and puts it after completion of the
usb_control_msg, so that the usb control message can always be
sent to one active device.

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.

We set bAlternateSetting to zero twice. I kept the second one
(.bAlternateSetting = USB_G_ALT_INT_BBB) because that's more
descriptive.

The wusb_cap_descr_default is never used. GCC doesn't complain about
it because we have that line .bLength = sizeof(wusb_cap_descr_default)
inside the definition itself. Clang complains though.

In ezusb_read_ltv() we had a comparison (bufsize 0) which was never
true because bufsize was unsigned. I looked at the implications of
that. If we passed a negative number to ezusb_access_ltv() then it
would be used as the size parameter of the memcpy() because that
function uses min_t(int,
Hi,
Couldn't you instead do an unbind of that particular interface via sysfs?
I can unbind only full usb device not single interfaces on devices. When I
try unbind interface I get write error: No such device
My mistake - unbinding single interface is posibbble only in

Hello knowledgeable people,
I have a question regarding tcdrain() and kernel driver
drivers/usb/serial/ftdi_sio.c (for a family of USB-to-UART converter
chips from FTDI). I'm using an FT232RL and kernel 2.6.38-16. (The driver
code does not seem to have changed much between that version and 3.6.)
Hi Don,
The WD drive arrived today, but I can't reproduce your I/O errors on
3.6. I didn't try with 3.5 yet. However, I did notice that the device
really doesn't want to enter U1, but it will enter U2.
Can you test the following patch with your device and see if it helps?
If that doesn't work,

Almost nothing from this file is used, and the file will hopefully be
deleted soon. Copy the tiny portions that are used directly into
tegra_usb_phy.c. I believe that Venu Byravarasu is working on cleaning up
our USB driver, and those cleanups will remove
