Yes, it may be. That indicates that the hardware (adapter etc.) is ok and thus the device is recognized on the "linux"/os level but it's not made visible on the level of the android USB-Host api (it's the same e.g. with usb mice etc.). It may be that android tries to use it as some standard rs232 hardware or as serial mouse or something.
That's probably also the reason why "Sick USB 2 Serial Terminal" does not find your device: it's not visible on the api level. Like Tux, I would recommend using another kind of device too. The IOIO is great, but depending on your use case, it may be overkill. There have been other projects with usb 2 serial adapters. You may find recommendations via Google. Am Donnerstag, 28.
