USB Devices not working after 8.1 Update

[Bootman 650]

Hi folks,

Strange one, I have an Acer TravelMate P253 - Laptop was working great when I took it out of the box all USB ports working fine. Since I upgraded to Windows 8.1 the USB devices don't work. When I plug in a USB and check devmgmt I get error code 43 (Unknown USB Device - Device Descriptor request failed).

Anyone know how to fix this?

Have tried updating Bios, updating Chipset Drivers, also uninstalled all USB Root's from device manager and restarted the machine.

Thanks in advance

Try this, uninstall everything and hit the power button before everything starts to reinstall.

1. Press Windows Key + R and type devmgmt.msc in the Run dialog box to open Device Manager.

2. When the Device Manager window opens, you have to seek the USB device with whom you’re facing trouble. It may be listed under Human Interface Devices as USB Input Device.

If you don’t find it there, you can expand Universal Serial Bus controllers. Here, you’ll find a list of USB devices you’ve connected with your system so far. To find the one from the list for which you have an issue, you have to follow the trial and error method. That is, plug and remove the device and note the changes among the list of devices for Universal Serial Bus controllers. The entry which is appeared and then removed subsequently is the entry for issued device. Keep the device plugged in and right click over this entry, pick Properties.

3. In the device properties window shown below, switch to Details tab. Now click the drop-down menu for Property and select Device Instance Path. Note down the corresponding Value because we will need this value in further steps. By the way, this value iscombination of three IDs; namely Vendor ID (VID), Product ID (PID), Instance ID.

5. Navigate here:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\<Device Instance Path>\Device Parameters

Substitute the Device Instance Path part (after USB\) obtained from the step 3.

6. In the right pane of Device Parameters key look for the DWORD named EnhancedPowerManagementEnabled which must be showing its Value data as 1. Double click on the same to get this:

7. In the above shown box, change the Value data to 0. Click OK. You may now close the Registry Editor as well as Device Manager.

This guy is a copy and paste "tech". Can we get him out of here ?

Thanks, Sysfix. As Martyn the Mod cautioned you in your intro, we are NOT rookies here. We don't need someone pasting stuff in from WindowsClub.com. If we're at an impasse, you can bet that we've done our own googling.

Tried all of those suggestions.

Any ideas? Surely everyone else using the same model has overcome these issues after the 8.1 upgrade.

If you took it out of the box it must be quite new
I would be thinking more of a refresh or clean install would be quicker
think of the time you have spent so far.

It was a new laptop supplied by us. I literally took it out of the box to set it up.
First thing I did was to upgrade the laptop to Windows 8.1 - It came with 8 Installed. After I'd done this the USB ports on the right hand side wouldn't work. I know they were working prior to the upgrade 'cos I used some tools on my pen drive to clear some of the pre installed crap!

Wow, what a great reply! Even though I'm not personally experiencing any issues like this I sure do like the detailed explanation.

I plan on doing a "COPY / PASTE" into a word document to keep for future reference. I wish more people would answer issues like this in this type of format.
