Hi Tibor
From what I can see here the Acer Iconia 10 doesn't meet the minimum require specifications for Catalyst so this tablet is incompatible.
The minimum specifications are:
- Operating System: Android 5.0 or higher
- Processor: 64-bit CPU with minimum 4x Arm® cores (6x or more Arm cores recommended)
- Core speed: 1.5 GHz or faster
- Memory: 1.5 GB RAM or higher
You can find this information along with the devices we have directly tested on the Catalyst Compatible Device page
The dual usb port scenario is interesting so we'll do some investigation on that. We're not aware of any (popular at least) Android solutions with dual ports at the minute but I'm sure they do exist
