Hello Pratysuh,
I tried to create the usbmon log before that i tried once again
executing the test case 2(with the arguments you gave) by rebooting the
system then it passed.
Actullay if some test case fails then if I run any test case after that
then that test case is also failing, same happend with test case 2
previosuly.
And it seems these below values that present in testusb.c are not
suitable for running all the test cases for USB3.0.
param.length = 512;(s)
param.vary = 512;(v)
param.sglen = 32; (g)
I have chnaged above values to param.length = 1024 (that you gave )
Yes, for superspeed keep length as 1024.
and also param.vary
= 1024
With this I am able to run all the test cases successfully except test
case 8 and 13.
For test 8 pass argument something like this
./testusb -a -c 1000 -t 8 -g 32 -v 1024 -s 4096
for test 13 is broken.

@Sarah: Could you see anything unusual in the xhci debug log posted at
above link.
Regards
Pratyush
I am geting the below error when executing those test cases
8 - value too large for defined type
13 - invalid argument
I tried with different values but still could not make it run.
I think it is again to do with proper arguments fo them.
Can you please help me with the argument values that may be required for
them.
Thanks,
Raveendra

share your lecroy traffic capture log or usbmon log (if you do not have
lecroy)
Also share dmesg.
