The standard approach seems to be to iterate through all available USB devices until you find the one that matches your specifications. -- Peter Jeremy pgp0B07afpudf.pgp Description: PGP signature

When you say 'currently', is there something like that planed?

Unfortunately the program in question uses libusb and the configuration
only allows to define the device by specifying : and
there are multiple identical devices around with only iSerialNumber
being different from each other. Somehow I need to make sure the
devices in the USB hub are always recognized in the same order.
I guess one solution would be to generate the configuration each time
the program starts.

You would be better making a symlink using devd rules, something like
notify 100 {
match "system" "USB";
match "subsystem" "DEVICE";
match "type""ATTACH";
match "vendor" "0x0403";
match "product" "0x6001";
action "ln -s /dev/$cdev /dev/mydevice";
};

static usb device configuration
Is there any way I can make sure that the following device: ugen1.3: at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON bLength = 0x0012 bDescriptorType = 0x0001 bcdUSB = 0x0200 bDeviceClass = 0x bDeviceSubClass = 0x bDeviceProtocol = 0x bMaxPacketSize0 = 0x0008 idVendor = 0x0403 idProduct = 0x6001 bcdDevice = 0x0400 iManufacturer = 0x iProduct = 0x iSerialNumber = 0x0003 bNumConfigurations = 0x0001 Is always registered as: /dev/usb/1.3.0 Using a pattern match on iSerialNumber could achieve that but how would I configure something like that? According to the /etc/devd.conf manpage I could create a symlink but that wouldn't solve my problem.
