Can't you just use Igor's build scripts?

the rt2800usb drivers were not included in kernel modules.
I've built them for you, download OPI_kernel_lib(rt2800usb).tar.gz, unpack and replace /lib/modules/ in your instalation with /lib/modules from that file.

sorry, I forgot that you must also replace the kernel. Please download OPI_kernel_lib(rt2800usb).tar.gz again, it now contains also uImage.

Big thanks with rt5370 everything is fine.

Buytheway how i win overheating in debian.
echo 408000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo 1108000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
system become more slowly but no heat.

Best way for cooling heatsink or heatsink + fun
You can run at full 1.53GHz without any problem (with kernel compiled without BUDGET_COOLING), no heating at all.

Nice, I was just going to use a small copper heat sink.

The ubuntu system on OrangePi plus is only returning 2 CPUs, do you know why?

nproc returns 2.

Even with heatsink, CPU overheats and one or more cores goes off.
Only heatsink with fun ensures full speed cool run.
If the kernel is compiled with CONFIG_SUNXI_BUDGET_COOLING=y option (default), max frequency after some time is limited to 1.2GHz no matter how cool cpu is running.

With heatsink+fun and kernel compiled with CONFIG_SUNXI_BUDGET_COOLING is not set option I was able to get cool operation with all 4 cores on at 1.53 GHz

After 2 days running with average 60% CPU usage (Ubuntu Vivid):
orangepi@OrangePI:~$ nproc
4
orangepi@OrangePI:~$ cat /sys/devices/system/cpu/online
0-3
orangepi@OrangePI:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
1536000
orangepi@OrangePI:~$ cat /sys/class/thermal/thermal_zone0/temp
32
orangepi@OrangePI:~$ cat /sys/class/thermal/thermal_zone1/temp
30
orangepi@OrangePI:~$

nproc
Print the number of processing units available to the current process,
which may be less than the number of online processors
