Hi,

I got your point. I already developed Mass Storage system but for the HOST i am using my Own Windows Xp PC.

1) My first question for you is that did you use any stack for your HOSt or not???

2) Did you aware of mass Storage Class structure. your HOST must have to send a data in that formate and at the device side you have to decode it and i think for that you are using ready made mass storage drive. right?so for that u have to no worry. but HOST point of you you have to send CBW-command block wrapper ,CSW - command status wraper and data phase for mass storage class.

In short at the HOSt side you have that mechanism which follows mass storage class specification.

Best Regards,
