Hi there,
I realized after installing the last firmware for this device and making the way to use Samba and USB support, the CPU load goes 80% when I connect my USB powered fan to the HUB I use to use for the network service. Is this normal?
I installed the packages needed for the USB mount to work.
Any help will be appreciated
Really, a fan?
New LEDE feature...
Seriously, since the fan is the culprit, I would start with the USB drivers.
Yes, the router has 2 USB ports. Instead of connecting the USB flash drive directly to one of them , I use a HUB. Whenever not using the HUB for the thumb drive, I connect my USB powered fan to avoid using one of my computer. Once the fan is connected, the load keeps going up and up.
Those drivers are needed for Samba and NAS. The thing here is to troubleshoot the issue and look for a fix in the coming updates.
Not likely a LEDE issue.
A stretch, but if the fan is somehow overheating the port, it could cause performance issues.

Looks like USB overload.
How much current is your fan drawing? A USB tester is well spent money (there are also cheaper ones out there).
What happens if you connect the fan to a self-powered USB hub (i.e. a hub with its own power supply)??
According to another testing device, it draws like 5w~
When connected to a portable battery works fine. After a while of being connected to the Lede device, the overload decreases.
5W? Really? That would be 1A current draw vs. USB spec = 0,5A max.
No wonder that you are running into USB power troubles...
