Hello, Been writing a kernel driver to access an fx2 based board and having some trouble. I'd like to download vendor firmware into this but it wasn't coming up after the firmware download/reset (did the typical external first, inactivate internal codes next, full reset). So as a test I wanted to just reset (toggling cpu_regs 1 then 0) the base firmware (which has A3 support, the 'FX2 Loader' firmware). The device then started misbehaving. After this simple reset, I could no longer get the configuration descriptor, as I could before reset (no data, -61, returned for usb_get_descriptor(dev->udev, USB_DT_CONFIG, 0, dev->config_descriptor, sizeof(*dev->config_descriptor) ). The strange thing here, is that /proc/bus/usb/devices has the configuration information, as does Sysfs. Though I don't understand the call, a call to: usb_reset_configuration(dev->udev); after reset did not fix the problem. Anyone know how to get this simple reset to bring the device back to a query-able state?
