Hello, I have usb device, which is based on EZ-USB chip (AN2131QC). I have working firmware for this device which is proved to work under Mac OS X and windows. But when I plug the device into the FreeBSD machine and download firmware with ezdownload utility something strange occurred: the firmware written correctly, but new device doesn't appears on usb bus. The strange things: 1) If I reboot machine after downloading firmware to device, usb stack works correctly with my device. 2) When I remove usb from kernel and make it a kld module, full reload of USB stack does not help! What magic has take place during boot, which helps USB stack to find my device? By the way: trying to unload usb.ko after several attempts leads to kernel trap. Thanks.
