[arch-general] USB not assining port number
Morning all . Having a problem with a usb device it is an Adafruit Trinket on plugging the device in i get 3761.650687] usb 7-1: new low-speed USB device number 3 using ohci-pci [ 3761.839453] usb 7-1: New USB device found, idVendor=1781, idProduct=0c9f, bcdDevice= 1.05 [ 3761.839469] usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 3761.839473] usb 7-1: Product: Trinket [ 3761.839476] usb 7-1: Manufacturer: Adafruit but no USB port given lsusb gives Bus 002 Device 011: ID 1781:0c9f Multiple Vendors USBtiny Is there usb support for this device as i need to get this working as an update to an Antenna rotator that has a defunct no longer available display for direction Thanks Pete ( G6NJR)
but no USB port given
lsusb gives Bus 002 Device 011: ID 1781:0c9f Multiple Vendors USBtiny
what is this "usb port" that you expect? USBtiny is a HID device as far as I can remember. -- damjan

Well i was expecting something like /dev/ttyusb2 or some other such device for the programmer to pick up this is the sort of thing i was expecting [ 9290.292465] usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 9290.292469] usb 7-1: Product: CP2102 USB to UART Bridge Controller [ 9290.292471] usb 7-1: Manufacturer: Silicon Labs [ 9290.292474] usb 7-1: SerialNumber: 0001 [ 9290.348975] usbcore: registered new interface driver cp210x [ 9290.349003] usbserial: USB Serial support registered for cp210x [ 9290.349090] cp210x 7-1:1.0: cp210x converter detected [ 9290.359683] usb 7-1: cp210x converter now attached to ttyUSB1 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ an actual usb list to tell the programmes to connet to the device on Pete .

USBtiny does not emulate a serial port. The only way to access it is via libusb. -- FA

If it exposes a HID device you can talk to it in /dev/hidrawX just as you would in /dev/ttyUSB0. Filipe Laíns

Pete .
lsusb does not give you this information. If it is just a HID device as Damjan hinted it will not show up as ttyUSB* anyway. Perhaps it exposes a serial interface, in this case a tty device node would be exposed. Assuming the device does indeed expose a serial interface, I suggest you write a udev rule that will just rename the device node. This means when you plug it in it will not show up ad ttyUSB* or whatever, it will always show up as ttyMyCustomDevice, which will in turn make it easier for you to identify it. Something like this would work (/etc/udev/rules.d/99-my-custom- device.rules): SUBSYSTEM=="tty", ATTRS{idVendor}=="1781", ATTRS{idProduct}=="1781", ATTRS{serial}=="XXXX", SYMLINK+="ttyMyCustomDevice" If you will only have one of those plugged in you can remove the serial field, if not you will need to figure out wich ttyUSB/ACM* device is it and the run: udevadm info -a /dev/ttyUSB* | grep serial And filling out the serial field in the rule.
