Controller Based WLANs

Where could I get the USB console drivers for OSX 10.10 (Yosemite) and Windows 8.1?

Although the Aruba Support site has those drivers available here under 'Tools & Resources', up to date drivers for the CP210x USB to UART bridge VCP drivers are attached:

Windows XP/Vista/7/8/8.1 (v6.7)

Mac OSX  (Yosemite support)
