You may have already considered the following but some deaf people use Video Conferencing for sign-language calls - even on iPhones. Potentially lip-reading is also possible.
With regards to the original query mentioning USB2. Yes the classic Mac Pro models only have USB2 and newer higher resolution cameras - certainly 4K ones would consider USB2 to be inadequate although I would expect 1080p to work. However it is possible to fit a USB3.0 and even a USB3.1 card in to the classic Mac Pro. This would give you 5Gbps or even 10GBps speed which is current state of the art for USB.
