MxPS= 64 Ivl=5ms So I've deleted the hub and storage devices from your system, and am left with the above devices that might be the touch board. The last one looks like the "real" one, and it is saying it is a HID device, and so the hid driver is bound to it. So it really looks like the device is attached properly to the kernel. However, the HID protocol is a common one for companies to use to write userspace drivers for (it was the only way old versions of Windows would allow it), so they might be abusing the HID protocol to bind a userspace program to the device. What does /proc/bus/input/devices say about this input device? You might have more luck on the linux-input mailing list, as that's where the hid and input driver developers are. > HITACHI STARBOARD (FIRST MODEL) > root@minino:/sys/kernel/debug/usb# cat devices > > T: Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0 > D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 > P: Vendor=1477 ProdID=0008 Rev=13.13 > S: Manufacturer=eIT-Xiroku > S: Product=Optical Touch Sensor HTM131 > S: SerialNumber=002301101075 > C:* #Ifs= 1 Cfg#= 1 Atr=a0 MxPwr=500mA > I: If#= 0 Alt= 0 #EPs= 0 Cls=ff(vend.)

That might be the case, and if so, it's going to be a pain as it just looks like a serial device to the system, so you have to write userspace code to make it work like a touchscreen. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
