Can't open HID
« on: February 26, 2011, 10:50:19 am »
Hello,
Can't open/read/write a HID device (TEMPerHUM HID). :'(
I try the last version of "Hiddemo", the same result. For details see attachments with the log.
With the USBBrowser,I find out, that the service is "usbccgp".

Any idea to open the device?

Regards

Hello

Please check that your device is installed as HID device. Do you see it in Windows Device Manager in HID class node?

PS I'm sorry id my answer is too late. Forum engine breaks notifications for this message board.

Hello

Your log file shows that InputReportLength has 0 (zero) size.
Possible your device does not support input reports or something wrong.

Please note that if your device is default keyboard or mouse, windows does not allow to access them from HID api.
