Hi there,
I am trying to implement a communication between the host and a usb mass
storage device using ADSC cmd. The device is using the g_mass_storage gadget
driver. So far, broken pipe (-32) from the host side is all what I have got. My
questions are:
1. Could the device support ADSC cmd ev

Try echo "7" > /proc/sys/kernel/printk to enable all console log levels.
The numbers are corresponding to below:
#define KERN_EMERG "<0>" /* system is unusable*/
#define KERN_ALERT "<1>" /* action must be taken immediately*/
#define KERN_CRIT "<2>" /* critical conditions*/
#define KERN_ERR "<3>"
Try 'sysctl kernel.printk=7' where 7 is one of the levels defined in
"include/linux/kern_levels.h".

I am able to read my printk messages in the kernel buffer only after
unloading the module..
Is there some reason or configuration behind this.
I used a simple kernel module with only init and exit functions, and
after loading the module i cannot see the message printed by the
"module_init" func

You could try out kmemleak -

I am suspecting a memory leak in a kernel module that does layer 2
switching of data packets.
In the vmstat -m output the Num and Total keeps going up for the
kmalloc-512..
kmalloc-512 15232 15264512 16
Is this a clear indication of leak in the kernel or can there be false
