Hi all,
I am an employee here at JPL and my current task is to get some IR
camera's which claim to be UVC compliant to talk to linux. This is
the camera: http://www.thermoteknix.com/content/english/products/
miricle/110k/index.html
First let me say that I am so thankful for the work you have already
done in this area, you have given me a head start on this task.
The problem I am having is this. I downloaded and installed the
latest drivers from the svn server. The driver does not detect the
cameras. Upon further investigation I found out that lsusb -d 17dc:
0100 -v | grep "14 Video" returns nothing, so it appears that this is
not a UVC camera, except I am 99.9% sure it is. I was reading one of
the threads in this list and found out that I might be able to add
the Vendor id and Device id. So I added this to the file
/* Thermoteknix MIRICLE */
{
.match_flags = USB_DEVICE_ID_MATCH_DEVICE |
USB_DEVICE_ID_MATCH_INT_INFO,
.idVendor = 0x17dc,
.idProduct = 0x0100,
.bInterfaceClass = USB_CLASS_VENDOR_SPEC, // Also tried USB_CLASS_VIDEO
.bInterfaceSubClass = 1
.bInterfaceProtocol = 0,
// tried .driver_info as well
}
When I run lsusb -d 17dc:0100 -v I get the following:

Funny thing is, I am getting a bInterfaceClass as 0x0E which is the
flag for UVC right? But I am not getting this same info when I lsusb,
this is weird. So my question is is my entry listed above correct?
Are there certain parameters I need to supply that I haven't? And if
I am certain this is a UVC device how do I go about coercing the
uvcvideo driver to agree with me? Also is there an irc chat room
setup for uvc_driver devs?
Thanks in advance for the help,
