How come the log doesn't contain any SOF packets? > SSPLIT IN transaction 114 1 > HS No data 884.562 264 267 > > SSPLIT IN transaction 115 1 > HS No data 884.562 265 217 > > SSPLIT IN transaction 116 1 > HS No data 884.562 285 417 > > SSPLIT IN transaction 117 1 > HS No data 884.562 286 467 I see what you mean -- the log doesn't contain any CSPLIT transactions for the interrupt endpoints. Only SSPLIT. I'll need to see the scheduling information for these endpoints. You'll have to run a 3.13 or later kernel; then the important files will be under /sys/kernel/debug/usb/ehci/X/, where X is the PCI address of the EHCI controller you are using. Copy the files in that directory while the test is running.
