Hi, I'm just having a look at ugen, trying to see if I can get any action out of a USB-serial converter that has no existing driver. This is my first foray into the USB world so I apologise for any stupid questions...is there a good tutorial somewhere? To find my device I open /dev/ugen? and call ioctl(USB_GET_DEVICE_DESC). I look at the returned idVendor and idProduct and check them against my hard coded figures. From what I can see from usbdevs only the last 2 bytes are significant? usbdevs produces 0x0743 for the vendor but I get 0x20743. When I work out what end point I need to talk to I thought opened /dev/ugen?.? but I only have a /dev/ugen? device (I'm using -CURRENT and devfs). I'm guessing I'm on the track here so I wouldn't mind a pointer to an example or some documentation. Thanks for any help, Andrew
