Hi,
I developed a HID-device on a Intel/Marvel PAX270 Processor.
The Enumeration works fine and i receive Datapackets from the device.
But I need an OUT Endpoint to send data to my device(HID 1.1).
How can i send Data to the OUT Endpoint with hiddev.
thanks in advance for your help

Hi,
I'm working on a CY7C68320 which is an USB to ATA/ATAPI and HID device.
The interrupt pipe of the HID section sets its polling interval to 10.
When connected to an [USB 1 host and/or USB 1 hub ] or [USB 2 host through USB
1 hub]
it functions properly.
However, when connected to an USB 2 ho
Hi all,
I'm developing a simple USB device that reports itself as a HID
device, and uses interrupt transfers to send about 250 bytes of data
whenever an event occurs on the device. I've managed to communicate
with it and get the data using libusb, but I've found that if the hid
module is inser
Thanks folks for your replies.
I sure will have a look at libusb and the hotplug mechanism as an alternative.
Nevertheless, hiddev would deliver the required functionality I need, without
too much dependencies on other components.
I probably will provide both ways.

You need to make sure the user able to access the /proc/bus/usb/NNN/YYY
"files". A hotplug script can do that.

Arnaud,
thanks for your reply.
Because libhid is based on libusb and libusb is a usermode driver, does this
mean that the application linked with libusb must be running under root?
Please correct me if I am wrong.

You might also want to give a try to libhid
which is a userland HID library, based on libusb.
It's not complete, though it should answer your need...

Hi folks,
I have probably a bugreport for hiddev.
Scenario:
I am using hiddev to communicate with a HID device.
The communication is based on reports sent and received.
I notice problems with the older and newest kernels.
Several were fixed in the past but with 2.6.11.3 several problems are back.
Hello,
I'm doing a HID firmware with a 9603 from National/
8051 microcontroller ( application with the hiddev
driver)
The problem I have now is I can`t open the
/dev/hiddev0 (No such device error ), but one month
before I opened it.
The firmware is different now, I fix a lot of bug, and
I test it
