Hi ,<br>
Is there any way we can get the class type of the attached USB device through struct usb_device in a kernel module?<br>
<br>
I tried getting the device descriptor and interface descriptor and then
use them to get the Device and Interface Class and Subclass.<br>
<br>
struct usb_device_descriptor *descriptor = &usbDev->descriptor;<br>
<br>
struct usb_interface_descriptor *idesc = to_usb_interface(usbDev);<br>
<br>
Whenever I run my kernel module, I get 0 for DeviceClass and Interface
Class. I checked the meaning and it says its the information and to be
gathered through interface.<br>
<br>
Am I missing something here? What I want is to get the mount point /
device path of the USB devices. Like for Storage Device I would like to
get its mount path and for HID I would like to get its device path.<br>
<br>
