How to code a host application to talk to a HID device in Debian Linux
I got a trouble about communicating between host application and HID device (with a button) in a embedded Debian Linux OS. The both of them are working fine on ubuntu. When I insert my HID device on my embedded debian linux Unit, following message show up:
# usb 1-1: new low speed USB device using ehci_marvell and address 3
usb 1-1: configuration #1 chosen from 1 choice
HID device not claimed by input or hiddev
and in /dev folder some usbdev files are generated:
When I run my host app, and press the button, no any data transferring happened (check with CATc captured data). I know the host app run fine on uBuntu, because I know how to open /dev/usb/hiddev0 in my code. I don't know how to open this kind of file in debian linux. I tried use each files above, the button still doesn't work. Can anyone help me to point out if it is HID driver issue or coding issue.
Not sure how to fix this, but is the HID device identified if you run lsusb?
