Hello,
please give me some help on usb gadget drivers in embedded Linux.
I compiled the usb device controller driver (/drivers/usb/gadget/pxa27x_udc.c)

Thanks a lot

Hello,
I am writing MTP class driver for Cowon Mp3 player. The device has MTP as
well as mass storage class support. Although i registered MTP class driver
with relevant vendor id and product id, the same info is also available with
Mass storage class(MSD) driver, hence on plug-in, by default devi
Hi Nidhi,

Hi,
The function calculates the last byte in a page OF A PARTICULAR FILE.
static unsigned
ext2_last_byte(struct inode *inode, unsigned long page_nr)
{
unsigned last_byte = inode->i_size;
/* Currently, last_byte = file size */
last_byte -= page_nr << PAGE_CACHE_SHIFT;
/* Current
/*
* Return the offset into page `page_nr' of the last valid
* byte in that page, plus one.
*/
static unsigned
ext2_last_byte(struct inode *inode, unsigned long page_nr)
{
unsigned last_byte = inode->i_size;
last_byte -= page_nr << PAGE_CACHE_SHIFT;
if (last_byte > PAGE
