Using a USB HID sensor I can only seem to enumerate the device with the chrome.usb API on ChromeOS.
On OS X I can enumerate with the chrome.hid API with no problem.
What could be the reasons for HID devices not being identified as such on ChromeOS?
回答1:
It is possible the device is blacklisted by the Linux HID driver. If you can put your Chrome OS device in developer mode or connect the device to a Linux computer you can check the kernel log to see how the device is recognized. If all is well then there should be a /dev/hidraw node created for the device.
Can you tell me what the device vendor and product IDs are?
