Right click on one of the Intel....Universal Host Controllers, select Properties, Driver,  Driver Detail.  Does it show usbohci.sys as one of the 4 drivers?

[Advertisements]

Only 3 drivers for 3A34-3A39:

ushub, usbport, usbuhci.

Mine also have a usbfilter.sys on both my Win 7 & 10.  In addition I have usbohci.sys. But I have an AMD system

 

Open an elevated command prompt and type or copy and paste:

 

wmic path CIM_LogicalDevice where "Description like 'USB%'" get /value > \junk.txt

 

notepad \junk.txt

 

Hit Enter if notepad does not open

Open \junk.txt and copy and paste the text to a Reply

Too long to look at quickly.  Will get back to you tomorrow.  Wife wants me to watch TV with her.

You've probably told me already but I don't want to go back through all of the posts to look for it.  What is the make and model number of the PC.? (Serial Number too if it's an HP)

 

Open FRST.  In the Search Box

put: usbccgp.sys; usbhub.sys; usbport.sys; usbuhci.sys

 

Hit Search Files.  You will get one file.  Please post.

Should I system restore to the point before I recently downgraded my usb drivers?

[RKinner]

No leave it like it is.  Export:

 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Usb

[hmp3]

There is no folder named USB in that directory

OK.  Let's add one.  Download the attached usb.zip,

right click on it and Extract All then Extract.  Right click on usb.reg and Merge.  This is the key that tells it to give you the warning message or not

[hmp3]

Okay, Merged.

[RKinner]

I take it nothing has changed.

 

I forget what it was we were plugging in.  Assume it has a USB cable.  Can you verify that the cable is 2.0?  It might have a + as part of the USB symbol.  Look at the plastic within.  Is it white or black?

 

Does anything else give the same error?

[hmp3]

Epson V39 Scanner via a black usb2 Ashape to mini-usb-shape (the size that connects to a smartphone). The inner plastic is also black.

Tried another white cable but regardless the slow speed error appears.

But re-plugging in eventually solves it and scanner operates at full speed until a certain point after which the scanner no longer responds until I re-plug it in. I re-ordered the scanner twice, thats how I know the scanner isnt faulty.

I do have other usb devices such as a printer but don't receive an error however, with the smartphone-size usb connection,  I only have two devices that use it, my smart phones and my scanner. I don't see the slow speed error when plugging in my smartphones.

Look at the plastic between the pins within the connector.  Black is 2.  White is either 1.1 or 2

 

See if you can get a process monitor capture starting when you plug in the scanner and ending when the warning occurs.

 

I'm starting to think the scanner driver is at fault. 

[hmp3]

It's all black.

The usb speed warning also appears whenever I re-plug my Speechware Alcor Micro SD TableMike.

Additionally, my smartphone (with mass storage enabled) only transfers at  8-10mb/s, as does my new usb pen drive.

 

We've already done a ProcessMonitor Log for the scanner here.

Would you still like me to do a new ProcessMonitorLog?
