Enable test mode to solve USB problems?

ComputerGeek · 20 Jan 2015

A USB 3 device can be plugged into either a 2.0 or 3.0 port and it will work
A USB 2 device can ONLY be plugged into a 2.0 port.

Pardon.. but just a small footnote

USB 3.0 is backward compatible. A USB 2.0 device will work in a USB 3.0 port (but will run at 2.0 speeds, of course). As to why Crabby reported the mouse worked in USB 3.0 at one point? Crabby, might you have, in fact, put it in a USB 2.0 port? Otherwise, it remains a mystery to me since the USB 3.0 drivers have never installed

sp56164. Message said it didn't install, but then it prompted me to continue and now it looks like the USB3s are in the right place. Message says I need to reboot. I haven't done that.

I'm absolutely sure I had it plugged into a USB3 and it worked but stopped working after I plugged it into the only USB2 port on my computer.
Did you see the device manager screen shot I just posted?

Small footnote??? It's a huge erroneous statement I made a number of times in this thread.
- hit me over the head with a hammer Jerry.
Please hit me now

I don't know why I had it backwards sooooo many times.

Go for it Sheila - restart!

Crap. 52 52 52

hold on - try one more restart - disable DSE (or did you on the last one?)

If another restart / disable DSE doesn't solve both USB2 and USB3, time for the hail Mary.

Uninstall USB3.0 device / remove software
restart - disable DSE
is the USB 2.0 device back?

The key for this exercise to ALWYS disable DSE on every boot until this gets a permanent solution where you don't have to disable DSE.

We're close, very close.

CrabbyRightNow · 20 Jan 2015

I am cautiously optimistic. All the USB ports are working! DSE still disabled.

Slartybart · 20 Jan 2015

And your mouse works in any port?

There's still housekeeping and after looking at your C:\ drive, more than I expected. No big deal ... we can relax doing that work ..... as long as the USB devices stick!

Another reboot will be the acid test for stickiness - this time you do not want to disable DSE (I know I said.... but this is the test for normal operation)

CrabbyRightNow · 20 Jan 2015

The mouse works on every port. I assume I will have to keep disabling DSE every time I reboot.
Thank you so much for getting this back up for me. You are a prince and a gentleman. You, too, Jerry.

Now I am going to bed and will worry about the other stuff tomorrow.

Slartybart · 21 Jan 2015

Umm, yes and no.

Tomorrow, I want to make sure that a normal boot doesn't lose the USB devices.
So on the next boot, do NOT disable DSE.

If the devices still work - great!

If not, one more cycle through the process using the Intel driver will hopefully fix this once and for all.
I'll write that up tomorrow and post it.

Tomorrow try the normal reboot.
- get a good night's rest tonight - you deserve it.

Thanks for keeping me honest Jerry - I think I corrected (struck) all of my erroneous 2.0 / 3.0 statements.
