I want to write a usb driver for my device ! But when i read some samples , i find there some information about definning the value to match the device,eg:
#define USB_SKEL_VENDOR_ID 0xfff0
#define USB_SKEL_PRODUCT_ID 0xfff0
My question is how to know the values about the device,or how to define the value to match the devices ?

You can try to plug the usb disk and see which device is assigned (es. /dev/sdb). Then try

Code:

$ udevinfo -a -p /sys/block/sdb

grep for product and vendor and you will find it.
