Hi!
The new ohci-hcd driver in 2.6 doesn't work for Power Management on Apple laptops at least. I've studied the code, but since I'm not very familiar with the whole new hcd architecture, I'm sure I'm still missing a lot.
This is with 2.6.0-test3-latest? I don't think PM itself is currently expected to work ... much less any particular driver.
It should work. Every time I try to test it its okay... (And every time I try to *use* it, it does something very wrong).
Don't you just hate it when software does that? ;)
There were a few small updates to that code last week. But the last time I checked there were still PM bugs in the PCI code (Pavel had a not-ready-to-merge patch). Plus, recent PM merges broke the APM support (it relies on the device_suspend routine, which no longer does anyting). So every platform where I've been able to use power management is currently broken -- no fault of USB.
I have some patches pending, but I have yet to make them work at least for me. PCI suspend is triggered two times (once via pm_callbacks and once using driver model), but if I kill one of those, it stops working. Ouch.
Yeah, I'm basically still waiting for PM itself to work as well as it did in 2.4 with APM before I try new stuff (swsusp etc).
It seemed to behave for a while before that last set of PM fixes got merged. I see some more got merged last night; but I'm not sure when I'll have a chance to check them out.
