USB Suspend Linux Kernel 2.6.23

[teknoaxe]

Hi there!

Long time no type! (I know, you're probably saying to yourself who the heck is this guy?)

I'm currently working on a project that is research into a way to selectively suspend a USB port or HUB from the Linux Kernel 2.6.23. I've read various hints that it can be done in google searches and a possible confirmation from our USB HUB vender, Cypress, but there's little to no concrete documentation on how this is done.

I was wondering if any of you have any knowledge of where to go to learn how this sort of thing is done, whether it needs to be hard-coded in C or some basic command line entries can do the job. I'd love to know, or would like to know if this is a feature not yet dealt with specifically in the Linux 2.6.23 kernel.

Thanks!

Matt

I suspect that there is some USB command to do this, which will probably require some low-level I/O command sent to the USB device. Since I haven't done any USB-specific kernel programming, this is about as far as I can take you. Sorry if this isn't much help...
