USB suspend problems in 2.6.37
 

I used to be able to suspend with my previous kernels that was older than 2.6.33.
My new kernel IS compiled with USB_SUSPEND support but I still have problems.
When I do "echo -n suspend > control" (or > level) I get this error message:

-su: echo: write error: Invalid argument

(I can echo "on" and "auto" to control without problems)

My current kernel is 2.6.37 but I have the same problem in 2.6.35 and the computer is a Hewlett-Packard -HP Compaq 8000 Elite.

Anyone has any suggestions?

It could be a regression (happens sometimes).

Just curious: What about 2.6.37 do you need to have?
