Hello, I have a HP Pavilion dv6 with Windows 7. I really like the laptop but I have the following annoying unknown device listed in device manager:
ACPI\ENE0100 *ENE0100 Can you help me find the right driver? Many thanks in advance.
Answer. The ACPI\ENE0100 is generally the “ENE CIR Receiver”, you can download the driver here:

Follow-up Q. from Charley C.
Thanks a million! That driver worked and now I am all set. One question though… what the heck is a CIR Receiver? And rate 4.5 out of 5 very good rating 🙂 [starreview tpl=16]
Follow-up Answer. Glad the driver worked and solver your problem! CIR stands for “consumer infrared receiver” and I believe ENE is the manufacturer of the chip used in the receiver. Thank you for your rating!
More info:
Driver should also work for HP Pavilion dv1030us and probably the dv61230us.

Since 1 week I am bearing with a nagging issue: ” Unknown device under Universal serial bus controller in device manager” with a yellow triangle. I performed these steps:-
1. Tried Updation via on line search but showing “the best driver is already installed”.
2. Tried Updation via ” Browse My Computer for driver software but showing Code:43 error”
3. Tried uninstalling but with every restart it automatically came back with a notification” Device Driver Software is not successfully installed”
4. At last I went for formatting my laptop hp “dv4-2106tx” but the problem is still there.
5. I also tweaked battery power option advanced settings but no result.
6. Windows updation could not could not resolve this issue.
I need to get rid of this nagging issue. If any body want to have a remote accress then i am also ready.
Hey Adhiraj, the ACPI ENE0100 driver in my post is for the HP ENE CIR receiver, but your issue sounds different, a “USB Unknown Device” with a yellow triangle under Universal Serial Bus Controllers is a separate problem. The Code 43 error specifically usually means the device itself reported an error to Windows. Since reinstalling and even a full format didn’t fix it, it may be a hardware issue with that specific USB port or an internal chip. I’d suggest running HP’s own diagnostic tools (HP PC Hardware Diagnostics) to test the USB controller. If a specific USB port is always the one showing the problem, the port itself may be failing.
