Hi all,
I'm having a bit of an odd error here using this USB hub. I am talking to a RPi board over a UART connection from a linux machine. The Rpi is connected to the USB hub, which it recognizes as well as the two downstream devices. However, when attempting to send an image over the usb connection (Either to reflash an FPGA) or to retrieve an image from a camera the bus throws an error. I've attached a picture of my schematic as well as a picture of the error I received over the terminal. We do use a custom usb driver to talk to the FPGA to reflash it; however, I don't believe this is a problem because we have this working using a different usbhub the XR22404, we are only switching over to this hub because of the expanded temperature range spec it has. The error I receive when trying to flash the FPGA is a LIBUSB_ERRROR_IO. I don't believe this is a software issue as this command works with the other hub.
