I’m looking for tips on debugging a driver/device installation problem.
On one customers site when new devices are discovered we’re getting an
error dialog indication that the installation failed (can’t remember
exact text in error dialog, sorry) for each new device.
After turning on more verbose logging I noticed the following in the
setupapi.log file:
…
@ 17:44:36.353 #E057 Registering coinstallers failed. Error
0x7ffd9000: Unknown Error.
@ 17:44:36.368 #E157 Default installer failed. Error 0x7ffd9000:
Unknown Error.
…
Where can I find out what error 0x7ffd9000 is and/or what coinstaller
it’s trying to register.
My driver is a disk filter driver and this is on Win XP SP 2 - I’m a
bit confused as to what’s going wrong, I haven’t seen this happen with
our driver before. I’m suspecting a third party conflict but it’s a bit
early to point fingers.
TIA,
