Hi
Niibe,
I
am doing a project that involves testing a ohci based host controller
driver for a PCMCIA card. The card has a USB port on it and i want
to manually power off the port (without ejecting the card of course),
either by a shell command or by an application (user space)
program

There are some problems with compatibility of the OTi's cable with plain PL2303
cable, as noticed by Werner Tuchan ([EMAIL PROTECTED]). Although it is claimed
on some web pages that the cable is based on pl2303 chip, it turned out that it

hmm. ok, I moved to flock() and now several processes have the same file
flock()#ed exclusively, i.e. that does not work either.
next fcntl()?
or are device files in any way special when it comes to flock(), fcntl() and
friend? I only want to make sure that only one process is talking to some
usb

Much appreciated Alan.
Thanks,

Hi Alan,
This isn't a simple mapping. A single USB device may correspond to 0, 1,
or more entries in /dev. Also, it's not clear why you want to know the
major and minor numbers rather than the filename of the /dev entry.
In that case, what would be the best way to know the device node on w

I tried once more, and this time with /dev/bus/usb only.
How can there be five processes with the same file opened?

Hello,
Is there a system call maybe an ioctl that can be
performed within usb storage driver to obtain the
major and minor numbers corresponding to those found
in /dev on a USB device.
I perform an open system call using usbfs i.e
/proc/bus/usb/001/001 and and use CONNECT and
DISCONNECT in the io

Hi,all
I have developed my udc driver at 2.6.14 kernel.
And I have two ko and need to insmod(dm320_udc.ko and
g_file_storage.ko)
In order to get convinence,i compile my code outside the kernel
tree.(both udc and file_storage ko)
the dm320_udc locates at /work/driver/usb/gadget.
Hi,
I have Linux 2.6.11 linux source with me which has the BSP stuff to
get to run on a ARM platform . For this a separate directory is there
in arch/ where the BSP stuff is written .
I am required to move to 2.6.16 . My primary aim is to write the USB
Controller driver for the ARC chip present on
