This device is made by me. It's just a board for demo and has 1 Control EP, 2 Bulk EPs.

I think the following lines do this. Those VID/PID are defined by my device and work fine in MS Windows's driver which is written by me.
#define USB_ZBOARD_VENDOR_ID 0x1234
#define USB_ZBOARD_PRODUCT_ID 0x0000
static struct usb_device_id g_ZBoard_IDS [] =
{
{ USB_DEVICE(USB_ZBOARD_VENDOR_ID, USB_ZBOARD_PRODUCT_ID) },
/* "Gadget Zero" firmware runs under Linux */
// { USB_DEVICE(0x0525, 0xa4a0) },
{ } /* Terminating entry */
};
MODULE_DEVICE_TABLE(usb, g_ZBoard_IDS);

I run 'man insmod' and find these words: This version of insmod is for kernel 2.5.48 and above.
So, is it ok for me to install my driver in 2.6.0?
Furthermore, I always login as 'root'.
Anyway, thanks for ur reply.
