I have a really old driver for a really old USB device based on an old
Anchor Chips sample driver. Yes, this is not the most wonderful driver for
a number of reasons. But it has been working for years, and it still works
on just about any version of 32-bit Windows that will accept unsigned
drivers.
Today I got a call that the driver was refusing to load for the device on a
customer’s XP machines. All of them. And all of these machiens had had the
driver loaded in the past, and had been able to talk to the device in the
past when it was plugged in. I tried the driver on about 8 XP machines I
had around, including some that had previously had it installed and some
that hadn’t. It works fine on all of them.
The guy brought over a laptop that is failing. The inf file and driver are
where they should be. But the device doesn’t work. Tried reinstalling the
driver and get a helpful “the location specified doesn’t contain a driver
for this device”. But it does, and it had previously been found there on
this very machine. But not now.
Turned on Setupapi.log messages to full debugging level, deinstalled the
existing null driver, and tried to install the new driver. The machine is
doing things I’ve not noticed a machine doing before. It is plowing thru
two different levels of inf cache files, and not finding anything in any of
them. Then it finally looks for the file I pointed it at. Normally it will
instantly find the driver here. But in this case I’m not sure that it is
even opening the inf file.
The only INF file on the system for this device is my INF file, so it isn’t
some other driver stealing it.
Below are good and bad clips from Setupapi.log files. has anyone seen this
before and know how to fix whatever is wrong? We really need to get this
device working on these machines again, that is why the machines exist in
the first place!
Thanks,
Loren
Tail of bad Setupapi.log: Notice it doesn’t seem to even taste the INF
