Unknown Device - USB error Code 43

Anonymous

Dell XPS m1330 running Win7 Pro 32-bit, service pack 1.

I have had this problem seemingly forever but have been ignoring it, as it doesn't seem to affect the performance of my laptop, but now I'm wondering why it has happened.

I have 7 Intel ICH8 host controllers, a Microsoft Keyboard and Mouse driver, USB Composite Device, USB Mass Storage Device and 7 USB Root Hubs that all seem to work fine, I have no problems using any devices I plug in to the machine, but there is an Unknown Device, with no hardware/device details available, reporting a Code 43.

I have uninstalled and reinstalled all the USB drivers, didn't help, in fact it made it worse as it seems to have lost my fingerprint reader (the reader is installed but apparently not connected to anything). There are no new driver updates. I have no idea what the Unknown Device is referring to, other than Port#0002 Hub#0001.

As I said, all external USB ports work fine, and until I tried fixing it, the Fingerprint reader was fine as well, I don't know what else should be on USB, so don't know what to fix.

Any help?

Thanks for your reply. I have a built-in fingerprint in my laptop and my laptop can not detect it anymore. This fingerprint does not appear in Safely remove list.

A built-in fingerprint scanner sounds like it won't be on USB port. This is a different problem for a different thread.

I'd suggest you find the Dell Resources discs that came with your laptop, one of them has the Fingerprint Scanner Suite and drivers on it. If that doesn't work, see if you can find a thread on here that is similar to your problem (probably not this one :P ) or start your own question. Good luck.

I have the exact same problem and the EXACT same details as Eskimo9 when I looked! (And I tried the useless uninstall BS advice already)

Hardware Ids:

USB\UNKNOWN

Compatible Ids

USB\UNKNOWN

Device Class

USB

Device Class GUID

{36fc9e60-c465-11cf-8056-444553540000}

Driver Key

{36fc9e60-c465-11cf-8056-444553540000}\0015

EVERYTHING is the same but I'm not on a Dell. It's a custom-built with a Sabertooth board. Intel(R) Core(TM) i7 CPU960 @ 3.20GHz (8 CPUs), ~3.2GHz

So got any bright ideas why we're seeing the EXACT SAME details? I can't help notice you haven't replied with any kind of advice for over two months.
