Re: USB problems after resume from suspend in current as of January 9

on resume with a usbdevs -v I get ...

Controller /dev/usb0:
addr 1: full speed, self powered, config 1, OHCI root hub(0x0000),
AcerLabs(0x0000), rev 1.00
 port 1 addr 2: low speed, power 100 mA, config 1, USB Mouse(0xc00c),
Logitech(0x046d), rev 6.20
 port 2 powered
 port 3 powered

Regardless of whether the mouse is plugged in or not. I also tried
plugging in an intellimouse explorer & a usb keyboard, both of which
failed to work, neither were powered up at all. 

I should note that under 4.7 suspend and resume works fine. I tried to
kill and restart usbd but no luck.  So for now I'm stuck with shutting
down the system.

Cheers,

Mark
