Hi, We have a hardware projekt where something is off with power ON timing. It sometimes gets started in a broken state where the device is seen by the USB system but does not respond to descriptor reads. When this happens this causes lsusb and libusb based tools to hang until the descriptor read in the USB subsystem timeout out after 30 seconds or so. It looks like the tools are trying to read /sys/bus/usb/devices/.../descriptors and it blocks until the timeout happens. We should fix our hardware and have done so in the next revision but why should one device be able to block the descriptors file that most user land USB code seem to use. Would there be any reasoning against just serving the descriptors file as it looked before inserting the broken USB device instead of blocking the read? And if we wanted to create a pull request for a change like that would it be accepted or would it be considered breaking the API? Regards Troels
