Hi, if the USB device id is different for the two usb devices then you might just write a custum udev-rule that loads the snd-usb-audio module with different card index parameters.. Regards, FPS On 12/8/2020 4:16 PM, Bill Purvis wrote:
I'm trying to put together a church organ, using two midi keyboards. Unfortunately, they both power on as channel 0. I can easily interpose a bit of jack code that changes the channel but I currently have no way of knowing which is which. They don't appear to send any useful information like serial number, and all I can rely on is that they will always be plugged in to the same slot each time (as it's all going to be cased up). I can put them on different USB Hubs if that is helpful. Any suggestions welcomed. Bill
