Specific to "test 14". >>> Yes I'm getting this too - with usbgadget on atngw100 2.6.29 connected to my MX21 HC I'll try upgrading to the latest mainline code to see if it changes. It also fails test 14 for < 64 control transfers [testusb -c 1 -t 14 -s 32 -v 31 -a] With this everything looks fine on the bus - the setup and 32 byte data packet are ACKd but I then I get a STALL. [text export of beagle trace below] The test then fails with error 32 (broken pipe) On the ATNGW100 side I see udc: ep0: TXCOMP: Invalid endpoint state 2, halting endpoint... After this nothing works anymore on the ATNGW100 side (not even enumeration) [reads of the device descriptor fail] but the MX21 side still works with other USB devices. Rebooting the ATNGW100 fixes it. All the other tests work. I'm suspecting this is a problem on the ATNGW100 side. Is there a way to force it to negotiate as full speed only so I can verify this with my PC rather than the MX21?
