I download the Firmware(Isochronous) using Cypress Console EZ-USB interface and check the get pipe info as
Get PipeInfo
Pipe: 0 Type: ISO Endpoint: 2 OUT MaxPktSize: 0x400
Pipe: 1 Type: ISO Endpoint: 6 IN MaxPktSize: 0x400
I am transferring the data through ISO TRANS pipe 0 with 1024 length, Packet size 1024 with 1 packet with the same hardware used for Bulk mode.
Isoc OUT Transfer
Isoc OUT failed
Would anybody tell me why the transfer get failed?

Hi
Transfer size in a ISO transfer using CYUSB must be multiple of 8 times of maximum packet size of endpoint.
which means in your case it must be 8*1024=8192.
Good luck.
