cubietruck i2c-tiny-usb


Recommended Posts

Hi,

I want to attach an external USB-I2C adapter (i2c-tiny-usb, https://github.com/harbaum/I2C-Tiny-USB).

As I understand, the existing kernel drivers should be invoked for this.

 

First I tried with Raspian, all went fine:

[   66.451429] usb 1-1.3: new low-speed USB device number 7 using dwc_otg
[   66.595547] usb 1-1.3: New USB device found, idVendor=0403, idProduct=c631
[   66.595562] usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[   66.595571] usb 1-1.3: Product: i2c-tiny-usb
[   66.595579] usb 1-1.3: Manufacturer: Till Harbaum
[   66.595587] usb 1-1.3: SerialNumber: 0150
[   66.633027] i2c-tiny-usb 1-1.3:1.0: version 2.01 found at bus 001 address 007
[   66.636876] i2c i2c-3: connected i2c-tiny-usb device
[   66.637519] usbcore: registered new interface driver i2c-tiny-usb

The same with cubietruck, kernel 4.13.16, i2c activated in armbian-config:

[9266171.211947] usb 3-1: new low-speed USB device number 4 using ohci-platform
[9266171.478997] usb 3-1: New USB device found, idVendor=0403, idProduct=c631
[9266171.479011] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[9266171.479017] usb 3-1: Product: i2c-tiny-usb
[9266171.479023] usb 3-1: Manufacturer: Till Harbaum
[9266171.479029] usb 3-1: SerialNumber: 0189

The driver seems not to be activated. Anything I could do for diagnosis?

 

Rgds, Holger
