Set req query output to a variable

Question

I want to get the output of the command below assigned to a variable.

reg query "HKLM\SYSTEM\CurrentControlSet\Enum\USB\VID_05E3&PID_0608\

If I run it from the Command Prompt, I get

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_05E3&PID_0608\5&1d69168d&0&3

which is what I need to use for a reg add, so, I am trying to assign it to a variable.

For testing, I wrote this batch script:

FOR /F "delims=" %%g IN ('reg query "HKLM\SYSTEM\CurrentControlSet\Enum\USB\VID_05E3&PID_0608\') do (SET RegPath=%%g)
echo %RegPath%
pause

But, the only output I get is the current directory - C:\Users\myname\etc.

My final goal is something like this:

FOR /F "delims=" %%g IN ('reg query "HKLM\SYSTEM\CurrentControlSet\Enum\USB\VID_05E3&PID_0608\') do (SET RegPath=%%g)

reg add %RegPath%\Device Parameters /v EnhancedPowerManagementEnabled /t REG_DWORD /d 0 /f

I know this should be simple, what am I missing?
