TivaC 1294 launchpad USB read issue

Other Parts Discussed in Thread: EK-TM4C1294XL

Hi ,

 Hardware : EK-TM4C1294XL

S/w : tirtos_tivac_2_00_01_23

   I am facing a problem in USB read  from printer class . USB Bulk IN endpoint configuration is proper. From the printer i will get an interrupt saying that the response data is stored in the output buffer. After receiving this interrupt i am trying to read through USBHCDPipeSchedule . But i always get the return value as zero.

  I am able to do USBwrite and print it, so i dont doubt the endpoint configurations . May be i am missing something for USBread.

Please let me know if i am doing anything wrong ?

Regards

Sai
