When the debug prints are enabled from libusb, I could see more packets ( example 5 packets each 163840 bytes ) were received by libusb. However, the callback was called only once ( example only 163840 bytes ) were received by the application using libsub. We are seeing this issue only past fews days and computers that has latest kernel updates. For example computers that did not update or kernel dated July 2015 or Jan 2105 are still working. Today I upgraded Linux kernel to 3.19 to test but no difference. With 3.19 kernel I goet following message in dmesg, [14720.137271] xhci_hcd 0000:08:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 4 comp_code 1 [14720.137282] xhci_hcd 0000:08:00.0: Looking for event-dma 00000000b25bd400 trb-start 00000000b25bd2d0 trb-end 00000000b25bd360 seg-start 00000000b25bd000 seg-end 00000000b25bdff0 [14720.138698] xhci_hcd 0000:08:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 4 comp_code 1 [14720.138706] xhci_hcd 0000:08:00.0: Looking for event-dma 00000000b25bd4a0 trb-start 00000000b25bd2d0 trb-end 00000000b25bd360 seg-start 00000000b25bd000 seg-end 00000000b25bdff0 [14720.140146] xhci_hcd 0000:08:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 4 comp_code 1 [14720.140155] xhci_hcd 0000:08:00.0: Looking for event-dma 00000000b25bd540 trb-start 00000000b25bd2d0 trb-end 00000000b25bd360 seg-start 00000000b25bd000 seg-end 00000000b25bdff0 [14720.140188] xhci_hcd 0000:08:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 4 comp_code 13 [14720.140192] xhci_hcd 0000:08:00.0: Looking for event-dma 00000000b25bd550 trb-start 00000000b25bd2d0 trb-end 00000000b25bd360 seg-start 00000000b25bd000 seg-end 00000000b25bdff0 Do you see any possible conflicts, with latest Kernels and libusb) ( esply for USB 3.0 ) Have anyone seen similar issues recently ? This is easily reproducible. Scenario that fails: -------------------------- 1. USB 3.0 device that can stream 16KB chunks. 2. Use libusb and submit more than 16K bulk read requests e.g. 160KB bulkread request to libusb. 3. start the data transfer from USB 3.0 device and the transfer failes at the end of getting data, i.e. when a short packet is transferred. However, the same logic worked for kernel versions below 3.13.0-71 ( including this version ) Scenario that works with new kernel ( but fails after sometime that might be our device and stack through put issue ) -------------------------------------------------- 1. in the above setup if I just reduce the bulk request size to 16KB instead of 160KB, then it works.
