Blink(1) doesn't get detected

Hi all,
Recently got a Blink(1)usb device but on archlinux it doesn't detect it. How do I say it doesn't detect is because the blink(1) has blink tool which can downloaded online and when I run it to list the blink devices it shows
"No blink(1) devices detected"
This device works on my office ubuntu machine and doesn't work on my personal archlinux.
Any ideas? what I need to do for it to work on Arch ?

Re: Blink(1) doesn't get detected

Does dmesg tell you that the device is being detected when you plug it in?

I don't think so because I did a watch on dmesg and when i plugged the blink(1) into usb i didn't see any update at all !

Re: Blink(1) doesn't get detected

Okay.  Now can you figure out what module is in use on ubuntu?  Is the module for this device in-tree or is it 3rd party?

Re: Blink(1) doesn't get detected

Does the regular kernel provide a module for this?  Or is the module shipped with the blink(1) software? 

I am basically just wondering if maybe the Arch kernel doesn't have the kernel config option turned on.  I have never heard of anyone else using this piece of equipment, though, so I am leaning towards the idea of this not being included in the mainline kernel.


Edit: Oh, I see that it is using the hidraw module.  That doesn't seem to be included in the Arch package.

Edit2:

 zgrep -i "hidraw\|hid_raw" /proc/config.gz                                                                                                                                                   
CONFIG_HIDRAW=y

Hmmmm.... it does seem to be turned on in the kernel.  Just not as a module.

Re: Blink(1) doesn't get detected

Sorry for bumping the thread but any idea where I start debuging ? what info I need to acquire in order for me to proceed further in figuring out the solution for this problem ?

Re: Blink(1) doesn't get detected

I know nothing of your device, but I've a few suggestions.
I checked and the Arch kernel driver  hid-thingm configured as a module.  Your device does show up as a raw HID device, so we know it is working.
I would suggest trying (as root) modprobe hid-thingm  and see what happens.  In the mean time, I am going to look at what udev does with this device.

Edit:  A look through the udev rules on my machine revealed nothing relevant to your device.  You might check if such a rule exists on Ubuntu.

Hi ewaller,
Thanks for the suggestion I did modprobe hid-thingm.
But still when I use the blink-tool to list the devices it says no blink(1) devices found.

Re: Blink(1) doesn't get detected

I got some more info  I looked at the diff between the lsmod command on ubuntu before and after inserting the blink device and I got this :
hid_thingm
usbhid
hid

I did try to modprobe the above modules still doesn't work.
Anything else that I need to try ?
