Raspberry Pi - Disable USB Sleep Mode

Instructions here:

In case it goes away:

Disable Power Management

First you read the power management flag using :

cat /sys/module/8192cu/parameters/rtw_power_mgnt

This will report a value of “1”.

To set it to zero you can use :

sudo nano /etc/modprobe.d/8192cu.conf

and add the following line :

options 8192cu rtw_power_mgnt=0 rtw_enusbss=0

To quit from nano use [CTRL-X], [Y] then [ENTER].

You are now ready to reboot using :
