i.e. the line about hotplug_libusb.c:440:HPEstablishUSBNotifications()
does not show up; and a truss shows that is is doing/waiting on
something on a dev; it is very slow doing some ioctls:

openat(AT_FDCWD,"/dev/usbctl",O_RDONLY,00)     = 11 (0xb)
ioctl(11,USB_READ_DIR,0xdfdfcb38)                = 0 (0x0)
openat(AT_FDCWD,"/dev/ugen1.1",O_RDWR,00)      = 12 (0xc)
ioctl(12,USB_GET_PLUGTIME,0xdfdfcb1c)            = 0 (0x0)

Hi,

Did you try this device with another real machine?

Maybe it is a bug with the Acer C720 netbook's USB controllers that someone needs to look into?
