USBCV doesn't do performance testing. It does compliance testing. In Linux there's a similar tool called testusb. See http://www.linux-usb.org/usbtest/ > how to debug if usb - ehci interface is buggy in the system . (for eg > IRQ handling not proper ) . If it's working then you don't have to worry about debugging it. If it isn't working, start by posting your kernel log. > Also in linux kernel , what source files correspond to such type of > tool if any . The source file is drivers/usb/misc/usbtest.c.
