T4xU series no support information or files

Overall, my summary would be that T4?U is very similar to T4?S with EXP/EHS port replaced by a USB port, so you have to use USB expansion modules and USB EHS adapters. The default firmware is based on some fairly old code because T46S has a number of bugs fixed that are still present in T46U default firmware. Not much help, I know.

We bought a batch T46U by mistake because reseller marketed them as T46S replacement, which is not really correct. We ran into some bugs in the default firmware. I opened a ticket and got a sensible response and support provided a firmware image that resolved our problems, but unfortunately until the firmware is officially published I can't tell the call centre to use it. So we are not buying any T4?U until this phantom model line appears on the support pages and we can re-evaluate our options. T54W seems like much better option than T46U IMO, and where we are only $20AUD more. If Bluetooth or WiFi is required then the cost of the adapter for T46U will offset that price difference.
