Hello Everyone,

I am currently trying to run a piece of really cool hardware (http://www.emotiv.com/) using N900.
The device comes with a wireless receiver that provides a raw hid data. I have this running on my linux box fine, reading from /dev/hidraw1.
I have installed hostmode, everything seems to work fine.

I have added to /etc/udev/rules.d/ file epoc.rules

Code:

ATTR{manufacturer}=="Emotiv Systems Pty Ltd", ATTRS{product}=="Receiver Dongle L01", NAME="eeg/epoc%2", SYMLINK+="epoc%n"

#Research headset
SUBSYSTEM=="hidraw", ATTRS{interface}=="Emotiv RAW DATA", NAME="eeg/encrypted%n", SYMLINK+="eeg/encrypted", MODE="0444", RUN +="decrypt_emotiv.sh research"

This work on my linux machine, when connecting the receiver I get:

Code:

[19122.457101] usb 5-2: USB disconnect, address 4
[19128.476117] usb 5-2: new full speed USB device using uhci_hcd and address 5
[19128.687209] generic-usb 0003:1234:ED02.0007: hidraw0: USB HID v1.11 Device [Emotiv Systems Pty Ltd Receiver Dongle L01] on usb-0000:00:1d.0-2/input0
[19128.696224] generic-usb 0003:1234:ED02.0008: hidraw1: USB HID v1.11 Device [Emotiv Systems Pty Ltd Receiver Dongle L01] on usb-0000:00:1d.0-2/input1

However, on my N900 I get:

Code:

[12307.422149] usb 1-1: new full speed USB device using musb_hdrc and address 25
[12307.570587] usb 1-1: ep0 maxpacket = 8

1) Is my assumption correct that hidraw / hiddev are not in the kernel?
2) Is there any good soul that maybe have the kernel recompiled with those modules or someone could help me with that? (I'm not a kernel proficient person).

Thank you!
