So this might be a stupid question, so flame away if deserved.
If we are going to run external power, is there a right angle USB cable that would allow the unit to sit on top of our bags, etc.? I don't see a straight USB cable being that secure or fitting in a Nova 5 the way I'd want it to.
Just something to stir up more "what if" conversation. 
If I were you I would go Digi in anyway, not USB. I would assume that the usb is for puilling the file off of the CF card if you didn't have a built in card reader on you computer. It is also used from my understanding as the charging port for the internal battery. Remember no question is a stupid question only the one not asked......... see not even a spark HEHEHEHEHEHE 
I agree that digi in would be the way to record. My question was in regards to the external power options. It appears to me that you are limited to 3 hours record time when using it to supply phantom power. That isn't so hot for festies. So just like we us Walmart batteries / RC packs / SLA's to power our rigs for festivals now, how are we going to power this baby?
The way I read it, the internal lithium-ion can only be "recharged" via the USB port. Will it be possible to rig an external battery to power the device via the USB port, or will this only allow us to "recharge" the internal battery as stated? If it only allows us to recharge, does that mean that we'll have to use a separate device to provide our phantom for festivals in order to achieve the 8 hour run time?
The right angle USB cable was a small portion of a bigger picture I was trying to convey.
