USB WirelessAC UBS Dongles poor functionality

[darkdrgn2k]

A previous thought that the AC dongles were under powered and that's what gave them such poor performance/functionality

Found this reference on the internet:

I just had the idea to set max_usb_current = 1 in /boot/config.txt to make the PI supply as much power as possible to the USB port.

Be worth taking a look to see how well/poorly they preform with this turned on and off

as possible

That scares me. Needs testing I guess, but I worry about other devices, and the pi power, etc. It'd be good to see some documentation for it.

if you can find it please post

at the moment it's a hypothesis only

When setting channel to anything other then 1 the driver seem to scan through all the channels and settles on 1 anyway.
