    SuJi_4691191

      Information of my project:

       

      1,  Chip is CY7C68013A and bulk frame length is 64.

      2,  Library in Cypress Suite USB Release 3.4.7 is used.

      3,  Bulk data length is  16*1024 when call BulkInEndPoint::XferData().

       

      BulkInEndPoint::XferData()  is failed occasionally with data length less than 16*1024 when i plugged into a USB flash disk.

       

      When  will BulkInEndPoint::XferData()   return fail or without enough data ???
