I'm thinking about constructing a small radio stack (ATC, NAV x 2, COM, ADF) using OpenCockpits. There are two options:

1. Buy plug and play modules, connecting each via a USB hub back to the PC.

2. Buy the basic radio IDC modules together with a master and USB expansion cards so that there is only one USB cable back to the PC..

Ignoring cost, option 1 seems the easiest, but I already have many USB devices already connected via hubs, (including two Mobiflights) together with USB screens, joysticks etc. I wonder if running 5 modules into yet another hub might be a problem.

Option 2 is the more "sensible" - ie, only one USB cable 'powering' all 5 modules via the interface card. But perhaps this is no different to using a single powered USB hub for 5 modules?

Any comments from those with knowledge of the potential impact when using so many USB hubs and devices?

Hi Paul,

the number of USB-connections (direct or via Hub) is limited by you OS. Normally Win 10 can manage up to 127 USB-Devices (with restrictions). That is depending of you PC-Hardware.

I myself have 2 10s USB-hubs (external powered). Here I use 7 slots for MobiFlight and 6 direct with P3D/FSUIPC and 2 Leo Bodnar-interface cards without any problems.
Here are users who have built their complete HC with MF-modules and they do not have any problems with USB.
How many USB-connections will you install for your construction at all?

Hi Stephan,

Thanks for the sanity check. I guess at the end of the day it probably only makes a small amount of difference with either case for this particular application. It all ends up as USB eventually.

I may actually make these myself and interface with Mobiflight. The lack of email response from vendors the primary motivation ;-)

Hi Paul,

everything ends up as USB? Oh, I hope the next beef ends up as a steak on my grill and not somewhere as a USB. That would be sad ;)
