So long as there is no effort to make Omega2 as one of the Arduino supported boards
(i.e., as a part of the Arduino platform),
it is a waste of time trying to port sketch over.
Currently, AFAIK, there is no such effort in place at all.
Internet of Things (IoT) is a romantic marketing term created in recent 2-3 years.
There is no criteria nor standards on the IoTs. Some will rebrand a product existed for many years (way before IoT days)
as IoT to "catch the wave".
However, what I can say is lots of IoTs are cheap and sub-standard in many ways.
Cheap and quality go opposite ways.
Will the camera in the system be visible as usb device?
Q (if USB webcam connected to Omega2's serial port)
Q (if USB webcam connected to Omega2's USB port)
A Yes, will be recognized as a USB (webcam) imaging device. All subject to a suitable device driver's availability.
Q if webcam's USB connecting to USB-serial dongle
A NO (both are USB "end point" devices, end point device needs to talk to a USB "Host")
To prevent overrun of its (end device's) input buffer,
slowing down Omega2 side's sending rate is the king.
Flow control signals (RTS/CTS), after all, are just signaling flags in between two devices.
The sender should slow down in the first place.
On power dock's power input side, it appears not using USB's D+ and D- signaling leads. It should force the supply side to be 5V supply.
ACT2801's max input voltage is 6.5V and at 6V, it will trigger an input over-voltage protection, until the issue is resolved.
BTW, Currently the charging current is set at 500mA. An external power supply has to have enough power rating (and USB cable has to be thick enough) to supply power for both the battery charging as well as for Omega2's own consumption.
Just to add
The datasheet seems to state (my interpretation) that light load current detection , if continuously low, for 16 seconds, it will trigger the boost off/power down state.
If that is the case, you may try to turn on some load (say a few LEDs) every 10 second, but only briefly, say 0.1 second pulse.
