Hello,
During porting uath(4) to usb2 I found the following code failed to run:
data = open("/dev/usb/0.2.2", O_WRONLY, 0);
timeout = UATH_DATA_TIMEOUT;
if (ioctl(data, USB_SET_TIMEOUT, &timeout) < 0)
err(-1, "%s: USB_SET_TIMEOUT(%u)", datadev,
UATH_DATA_TIMEOUT);
and the error was:
uathload: /dev/usb/0.2.2: USB_SET_TIMEOUT(1000): Invalid
argument
It looks it's ok with calling ioctl(msg, USB_SET_TIMEOUT, ..) to
/dev/usb/0.2.1
And the behaviour of program isn't likely with usb1 that it worked well
in usb1. After writing some data into msg and data pipe there was no
any response using read(2). The problem source can be found at:.

Are there something I missed in here?
