Log: Initial commit of my USB test code which can exercise connected USB devices and the FreeBSD USB stack itself. This program can be used to test compliance against well established usb.org standards, also called chapter-9 tests. The host platform can act as either USB device or USB host depending on the available hardware. The basic USB communication happens through FreeBSD's own libusb v2, and some sysctls are also used to invoke specific error conditions. This test program can be used to verify correct operation of external USB harddisks under heavy load and various other conditions. The software is driven via a simple command line interface. Main supported USB host classes are "USB mass storage" and "USB modems".
