Hi all
I have a USB host controller on a application board.
The OS is Linux kernel 2.6.12
Now i want to test the USB host controller.
Please explain

Hello
We are running Linux 2.4.20 on a custom hardware. We are using a USB based
3M touch screen. After Linux comes up, the touch screen is responding. We
use JRE for the UI and when we touch the screen while JRE is being untarred
the touch screen stops responding after a few touches.
We tried th
Hi,
I am trying to write a bulk transfer driver based on
usb-skeleton.c.
I am using prolific usb host-host cable (vendor id
=0x67b and product=0x2501) with 2.6.11 kernel patched
with 2.6.12 rc5 patch.
I am not able to flush the buffer once it has been
read. Suppose I write 1024 bytes and read

You can find the relevant documentation for conformance testing
on the USB.org website:

To allow multiple platforms to use the PXA27x OHCI driver, the platform
code needs to be moved into the board specific files in
arch/arm/mach-pxa. This patch does this for mainstone and adds
preliminary hooks to allow other boards to use the driver.
This has been compile tested for mainstone and s
Alan,
You are excactly right! The device files should be 08:01. After fixing
the device node (/dev/sda1) in my device table and recompiling, it
mounted just fine. It was indeed reading the first sector of /dev/sda.
Thanks for your help!

I am having a problem using Samsung S3C2410 ARM with
UDC RNDIS gadget driver and 2.6.13 kernel, the
initialization of the UDC gadget interface:
0.00 USB: s3c2410_udc: version 28 Aug 2005
0.01 USB: s3c2410_udc_probe
0.02 USB: udc_disable called
udc: pullup(2)
0.03 USB: usb_gadget_register_driver()
Regression. It hangs here:
ohci_hcd :00:02.1: new USB bus registered, assigned bus number 3
ohci_hcd :00:02.1: irq 20, io mem 0xd0001000
hub 3-0:1.0: USB hub found

This patch tightens handling of interface "power state", and
adds a useful invariant. Now the "power" is PM_EVENT_ON only
if (a) some driver is bound to it, and (b) it's not suspended.
- Dave
This updates the handling of power state for USB interfaces.
- Formalizes an existing invariant: in
As previously discussed, this removes some code we don't actually need.
(A separate patch will address resume-path recursion.)
The change is user-visible in that writing to sysfs power/state to
suspend USB devices now returns errors if the children aren't ready.
However it only affects CONFIG_USB_
This removes some other code we don't need, in this case because we
have other code that by now does the same thing.
- Dave
This gets rid of some inconsistently duplicated logic to resume interfaces.
Similar code was in both finish_port_resume() and in usb_generic_resume().
Now there is just one c
The parameter isn't needed, or even usable, without the recursion
removed in the previous patch.
- Dave
This patch removes the extra usb_suspend_device() parameter. The original
reason to pass that parameter was so that this routine could suspend any
active children. A previous patch removed t
For various historical reasons, some code was testing the wrong CONFIG_
symbol. Only S3C2410 OHCI was at all broken by this though. This will
matter more later on, when the two root hub suspend paths merge.
- Dave
This simplifies some of the PM-related #ifdeffing by recognizing
that USB_SUSPEN
The next five patches are small incremental steps that shrink
the difference between configurations with CONFIG_USB_SUSPEND
enabled, and those without it. There will be other such steps,
since eventually we want that config option to vanish.
