Fix enumeration process crashed with stall status when enumerating devices which return
bConfigurationValue
with non standard value in the configuration description.I encounter the bug when I try to connect a serial device from Netchip Technology. The device responses the request for first configuration with bConfigurationValue = 2. But in current code, the
config_num
is hardcoded to beENUM_CONFIG_INDEX + 1
which is 1.Here is the pcapng when I connect the device into PC.
