Hi Alan We are not still able to get the device to respond .The command sequence that we are using:
1. Read 10 - response is STALL. We then clear feature command. And a Bulk in to retrieve the CSW of failed Read 10. 2. Request Sense: 18 bytes of sense data and CSW. Sense data shows 06 - UNIT Attention condition. 3. Read 10 Stall again. How do we resolve this issue? We are using an OHCI controller and the device is USB 2.0 compatible. Is this a factor? Should we give a specific amount of time between a UNIT ATTENTION condition and next Read 10. We have also noted that all medium access commands fail but others like Read Capacity, TUR, is successful. PS: Siddharth is my mentor.
