USB HID support #350

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
Hello.
Is there kernel support for USB HID devices?
I have a Temper1 USB temperature sensor/logger that is detected as an USB FTDI 
device. Any chance to get it detected as an HID device?

Thank you
Rui

Now, for some reason the device is detected differently, and OHCI is being 
used..

"kernel: usb 2-2: new low speed USB device using str8100-ohci and address 4"

Any chance that the FTDI thing is just from the ftdi_sio driver getting loaded?

It looks like there are userspace "drivers" for those things.

I just don't know which one is the best one.

Yes, i think it uses "user space drivers", but i tried several options and 
can't get it to work on SnakeOS. Works perfectly with Ubuntu.

If no one tried this devices with SnakeOS i guess i will keep trying.

thanks

Well.. does the attached binary do anything? It's this thing: 
https://github.com/bitplane/temper. I can't test it.

It tries to find the device but it's unsuccessful. I have to do more tests.
I think different applications for that device use different approaches to find 
it.

Would it - theoretically - work through Debian Chroot? The devices folders are 
linked to the SnakeOS ones like in the FAQ. No success with that too.

Too bad. They should work in the chroot too. I think they either look under 
/dev or /proc for usb devices.

I got the first two compiled there with something like:
apt-get install build-essential git-core libusb-dev
git clone git://github.com/jeixav/HID-TEMPerHUM.git
cd HID-TEMPerHUM
make

I also compiled in Chroot without problems, but the device is never found by 
the software. I admit i don't know that much about linux devices and was 
avoiding to spend much time around this (i can use a Raspberry Pi for this 
project). I know some software for this device tries to find one of the known 
device IDs, but others check for the device itself at /dev . I think i tried at 
least one of each, but with no success. I don't know if it's important how the 
OS detects the device when user space drivers are used or if there's some kind 
of dependence between the two.

But it's a shame, because this cheap little device with the cool SnakeOS was 
more than enough for my needs.  Thanks anyway!
