Your device follows the CDC ACM specification, aside from the incorrect subclass. Such devices don't generate /dev/ttyUSB devices nodes. They generate /dev/ttyACM nodes. > sja@UBUNTU-10:~$ sudo modprobe usbserial vendor=0x0c6a product=0x0005 That is the wrong driver. usbserial is for vendor specific serial devices. Your device follows a class specification. You need cdc_acm. As soon as the subclass is fixed, it should autoload. If cdc_acm doesn't bind, please post "dmesg".
