Unsuccessful transactions during usb enumeration

2014-06-17 Thread Ranjith T. C.
Hi,

I am using a device with Marvel USB controller in device mode with Linux 2.6.22 
running on it.
During the enumeration, I am getting so many unsuccessful  transactions in my 
USB packet sniffer.
Can anyone please tell me the possible reason  for this?

Any help in this regard is much appreciated.
Please copy me in the further communications.

Regards,
Ranjith

RE: gadgetfs : hangs during repeated communication with PC

2014-05-24 Thread Ranjith T. C.
Hi all,

I am using gadgetfs driver with linux 2.6.22.18 kernel for my device.
After some repeated communication with PC,gadgetfs hangs.
I can see that i am receiving the hardware interrupts in the ISR for the 
incoming USB packets.
But gadgetfs is still in a hang state. Has anyone come across this issue?

Any help in this regard is very much appreciated.
Please copy me in the further communications.


Regards,
Ranjith
