USB suspend problem with kernel 2.6.17

 Hi guys,

 We have an embedded system running kernel 2.6.17.14 (plus Mandriva patches)
which has the following problem: when we suspend it to ram with an external
USB device (which requires external power) attached, the machine doesn't
come back from suspend. But it does work fine with bus powered devices
attached.

 Unfortunately, it's not so easy to upgrade the kernel because the machine
needs some additional patches to work. We'll try it eventually, but we'd
like to get 2.6.17 fixed.

 We're still debugging it, and now we're going to try it with the minimum
amount of patches.

 Something important to notice is that Alan's 'usb persist' patch is
also applied.

 Is this problem familiar to someone? Any debugging tips?

 I've uploaded some information about the machine's hardware and
the usb persist patch we have applied to:

Thanks a lot.
