Can I manage power for USB devices from vSphere client or from SSH?
I use smart card readers (ruToken, Alladin etc.) and they hangs sometimes. On Linux it is possible with commands like this:
echo suspend > /sys/bus/usb/devices/usb5/power/level
echo on > /sys/bus/usb/devices/usb5/power/level
P.S. I use ESXi 5.0.0 host with Windows XP guests.
