The driver believes that it is failing to power up the hardware.
If the dongle works with OpenBSD on real hardware there is probably
some problem with the way VMware handles USB devices. Do other USB
devices work?
Perhaps things just happen slower than the driver is expecting?
The driver waits for 5 miliseconds before giving up.
You could try increasing the timeout a little by tweaking the code as
shown below. However, if this fixes the problem the driver might end
up timing out elsewhere, so quite a few timeouts in the driver may
need to be tweaked.
