For an embedded system what is the best way to verify a USB 2 compliant Host? e.g. I have a target produced by a third party and I need to sign off the target design. However, I am having troubles with the USB 2 Host Controller driver and a certain USB 2 device(s). The third party have tested the USB 2 Host Controller with a particular device and claim because it is an embedded Linux system it is impossible/unreasonable to test the USB 2 interface to work with all devices (this seems reasonable to me). However, I feel that there should be a method to test the USB 2 Host (hardware and software drivers) to the USB 2 specification. Thus perhaps purchase (if available) a USB 2 device with loopback that communicates through the drivers to the loopback device driver and can exercise all transfer modes (and other stuff?) of the USB 2 interface. Does this sound reasonable? If so what options are available?
