Hi, >> No, i don't see that (Set-Config request with a config value of 0) > > Well, then I don't know where the problem is, but obviously the problem > occurred before the gadget driver was involved. Either the host sent a > wrong packet, or more likely the UDC received the packet incorrectly. Yes, UDC driver has bug. After modifying it, it can receive Set-Config request with a config value of 0. However, the "device descriptor test - addressed state" still fails. Please see the attached log. The Set-Config request with a config value of 0 is the second last USB request sent from the host. The last USB request is Get-Config, which still returns config value of 1. Thanks, victor
