Same results on my laptop (Intel UHCI chip; the desktop uses a Via chipset). I can send the logs, but it's just more of the same (test 10 failures, and the UHCI driver dumps its lists).
Maybe I can try running the test program on my system over the weekend. The test will run okay if I connect it to a CD-RW device, won't it?
The control tests (test9, test10) should work with absolutely any USB-conformant device ... they only issue requests that every device is required to support. (And in some cases they're even considerate of common usb 1.1 errors, like not supporting {get,set}_interface.)
Not sure about that. I admit I haven't looked very hard for the source to ep2_inout, but I was under the impression that it performs a loopback on data sent to the chip. There seem to be provisions in usbtest for testing without loopback, but I'm not sure how much things change if the device (such as your CD-RW) just NAKs all the data coming in.
At one point I put together some loopback tests, and gadget zero will certainly talk to drivers (like some of the ones NetChip uses) that send and receive patterned data. But "usbtest" uses only bulk source and sink mode tests for now, not loopback.
