HPS, In FBSD7 I committed an ioctl on the ugen.c (some time ago) that allowed for resetting the device. Not a port on the device, but the device itself. This was a function that was unimplemented in libusb1 up to then. For example some Atmel devices need a reset after you uploaded the firmware. I cannot seem to find this functionality in usb_ioctl.h in teh FBSD8 USB stack. Another use for this feature is to be able to reset a device into a known state, like the 3G dongles that freeze. Power-cycling them is the short way out of the situation. Cheers, Nick
