I understand that this topic has been covered numerous times. However, after reading the other posts, I wanted to see if there are any fresh ideas or fixes. Thanks for taking the time to read my post.
Recently I've started having this USB power issue pop up on random computers. So far, it's happening on two HP Ultra Slim Desktops and two HP Probooks. All of them are using Win XP and every one of them is a different model. The I haven't yet been able to find a fix. I first noticed the problem when trying to setup an XP PC with a 3rd display, using an iOGear USB to VGA adapter. I then noticed that not only would it not initialize the adapter due to the "USB Hub Power Exceeded", it would not initialize a USB flash driver either. Peripherals such as mice and keyboards do not seem to be a problem. The problem then popped up on a computer that was working without issue with a 3rd display attached via an iOGear USB VGA Adapter. Suddenly, it's having the same exact issues as the previous. When asking the other tech around the office, one had a notebook that has been doing this for 2 months and another just started having the problem last week on a notebook. Neither of these notebooks were/are using a USB VGA Adapter.
The notebook that came down with the issue last week seemed to do so right after some windows updates were installed. These are the updates, that I was able to find, which were installed just prior to the issue starting: KB2898785, KB2893984, KB2893294, KB2898715, KB2892075, KB2850085, KB2917500. I did not see any driver update installation and there was no other software installed just prior. I uninstalled each of these, one by one, and the issue remains.
I can tell you that all the normal suggestions have been tried and that "you have too many things connected by USB" and "Hide the USB Hub Power Exceeded notification" are neither the issue nor the solution. I swapped the hard drive into a PC that I had tested to be working properly and the issue followed. That ruled out any hardware issues as far as I am concerned. I checked several chipset driver versions and the problem didn't change. I checked the BIOS for a setting to reconfigure the USB 3.0 ports to function as USB 2.0 ports. However, HP has a limited function BIOS on these machines, so I was not able to adjust the USB 3.0 function to allow Windows to use the native EHCI driver. I've turned off any power management of the USB Root Hub(s). I've "uninstalled" the USB controllers and hubs through device manager and then let the system re-install after a restart. I've checked the drivers that are being used for USB against other computers of the same models that are working properly and there doesn't appear to be a difference in the driver. So, I don't think that the drivers themselves have been updated or changed. I am stumped.
Does anyone have any suggestions or hunches? Please don't re-hash the usual suggestions from all the previous posts. As I said, I have tried all the typical suggestions. Thank you in advance for taking the time to read my post and any useful suggestions you may have.
