Make driver load automatically when USB device is inserted
I'm using a Limited User account under Windows XP, and I'm having a bit of trouble getting my Adaptoid (the most coveted N64 controller -> USB adapter, because of it's support for sending raw N64 controller commands + the fact that it's been discontinued) to work smoothly: as installed, the included software requires Administrator privileges to load the driver.
Presumably, it is possible to arrange for the driver to be loaded automatically when the Adaptoid is inserted by adding some stuff to the INF file for the driver (wishna1.inf): the question is, what stuff?
(It would also suit me just as well if the driver could be automatically loaded when anything attempted to open \Device\Wish_NA1, or even to have it automatically loaded at every boot, really, but doing it on insertion seems like the right way.)
Note: I do have access to an administrative account, it's just that I prefer not to have to use it day-to-day.
Answer
First of all, let's clarify that a USB device has a Plug & Play driver on Windows 2000 and higher, so services start modes are irrelevant. The driver will have an entry as a "service" in the registry, but its start mode is irrelevant here.
Let's split the problem into two parts:
Installing driver for the device: This requires administrative privileges. This happens when you insert a USB device into a port for the first time. Windows goes over your .INF files to find one that matches your hardware. If the driver is WHQL-certified, it'll load automatically. Otherwise, you'd see the dreaded Add New Hardware wizard. If you're running as admin, a few clicks on Next should be enough to install it. Otherwise, better have that Administrator password ready.
Loading the driver for the device: Once the device is installed, the driver will be loaded each time this device is inserted into this USB port without requiring any additional user intervention. Ever noticed how a USB printer, camera or disk drive load much faster the second time you plug it in? That's because that's just loading, without installing.
From looking at the .INF, it looks valid. Also, it's not WHQL-certified, so you'd have to install it manually.
I'm assuming when you insert the Adaptoid, you get an Add New Hardware wizard. If you point it manually to the installation directory, does the Adaptoid install and function? Does it appear in the Device Manager?
P.S. USB devices which have a serial number are an exception. They're installed once for all USB ports. Those devices are rather uncommon, though.
