SCART HDTV vs RCA TV power comsumption

I'm a software engineering working with a Set Top Box (STB) which has 
both SCART HDTV and RCA TV connectors.  I think I am having a power 
problem with the STB when I connect a wireless NIC into the USB port. It 
works great in RCA TV mode, but when I use the SCART HDTV settings, the 
STB reboots when the USB device is initialized.  I think that there is a 
significant power drain in the system when the wireless NIC initializes 
the transceiver. I also think that in HDTV mode, the power drain causes 
the STB to exceed some critical threshold which causes a reset.  Can 
anyone point me to the right direction to information about the power 
consumption of SCART vs RCA?

Thanks,

If you have a supply problem, maybe try with an externally powered USB 
hub, that way your STB shouldn't be strained too much.

OTOH I have seen a USB disk enclosure causing reboot of a PC at 
insertion due to bad drivers, so it doesn't *have* to be a power issue.
(so if it still cycles with the powered hub, you may have to dig deeper)
