Re: Problems With USBDeviceReEnumerate



% ioreg -l -p IOUSB shows the same vid/pid for two of the devices.
"PortNum", "sessionID", "USB Address" and "locationID" are all appropriately
different for all three devices.

I have found that if I pull the devices out and reattach them, the devices
all get back their correct vid/pid properties.
