Subject: [usb] Clarification on USB
Hi Folks
I have a Query on Usb.
suppose host puts IN token and send it to device .
2.Device takes more than the Bus turn around Time ( or
more than the bit times required to respond )
3.Host wil assume itz the Bus time out and intimate to
software.
4.Assuming this the host wil retry to the same Device
.
5.By that time whn Device responds for the previous IN
token it wil lead to Contention
How the above said Contention is avoided or
controlled.
Regards
Ravikumar
