Not as much as I had hoped.  Appears that when it gets an even numbered hub it works OK but odd numbers don't work.

 

Odd the table mike seems to have more info than the scanner.  Do you have something else that works that you can get a log from?

One more working USB accessory:

[RKinner]

Found a neat program from NirSoft called USBDeview

 

https://www.nirsoft....vices_view.html

 

Down near the bottom is

 

Download USBDeview for x64 systems

 

click on it, download and save then right click and Extract All then right click on the exe and Run As Admin.

 

It shows you all of your USB connections and even the ones that aren't there any more.

 

If you click on the Connected column header it will sort all of the NO's together.  You can select all of the NO's then File, Uninstall Selected Devices.  That will get rid of the ghosts of USB past.

 

Now slide the slider at the bottom to the right until you see USB Version column header.  This should show you whether a connection is 1.1 or 2.0.  Do you have any that say 2.0?

 

Select all of the present devices then File, Save Selected Items.  Save it as USBView and then attach or copy and paste the result to a Reply.

 

Do you have a USB flashdrive?  You can plug it up and run a Speed Test with USBDeview.  Select the flashdrive.  (Temporarily stop/disable your anti-virus and close all other programs) Then File, Speed Test, Start Test.  The test is very sensitive to the make of flashdrive.  I have one that gives me Write at 4.10 Read at 10.24 another that gives Write at 1.95 and Read of 17.13 (and a warning that it changed during the write).  Move your flashdrive around to each port and rerun the test.  Do you see any major differences between the ports?

I'm away from pc for 3 weeks, I'm concerned that uninstalling all the usb devices will lead to an unreliable computer when I return to catchup with other tasks.

I'll do the mass usb uninstall later. For now, I did the scanner and it reistalled when I plugged in, but speed warning returned also. I noticed that most devices don't have a usb speed written in UsbDeView, but the tablemike, surprisingly shows as USB1.1. There are others that show 2 and 1.1 respectively. Would you like me to do the usb drive speed test before the mass usb install?

[RKinner]

You don't have to do the uninstall.  It just makes things easier to read.

[hmp3]

Ok, thanks, I didn't uninstall the disconnected devices, but I saved a report of only the items that have a USB speed given.

[hmp3]

Used USBDeView (with antivirus and MWBytes, anti-exploit, etc disabled) to speed test a USB Pen Drive (Innostor Innostor USB Device).

I ran speed tests 3x per port,

Each time, speeds got considerably slower.

 

The publish test was greyed so I logged the results manually:

Ports tried: 1 hub 4, 2 hub 4, 3 hub 8, 4 hub 8, 6 hub 8

Read Speed: 9-28mb/s

Write Speed: 0.05-18mb/s

Significant drop in speeds during each test: Yes

There are two devices with USB Version       : 2.00.  One is a Card Reader and the other is your wireless keyboard.  Try moving the Card Reader (or the Wireless Keyboard if the Card Reader is fixed in place) to each USB port then run USBDeview and see if it shows up as USB Version       : 2.00 on each port.

 

Alternatively if the Pen Drive shows up as 2.0 then you can use it to test if each port is 2.0 capable.

 

The publish test just sends the data to a website that lists a lot of other devices that have been tested.  Read speed of 28 is much better than mine.  Write speed of 18 is also impressive.  I tried it on several ports of mine and they really didn't vary as much as yours.  Did you repeat the tests on the ports that showed super slow?  Does the Pen Drive show a different USB Version on different ports?

[hmp3]

Literally every port started at 18, then the 2nd test lowered to 8, then to 2. Every 3rd test for each port lowered all the way to almost 0 write speed.

The card reader is housed in the tablemike unit, so I can't move the card reader around ports without also moving the tablemike.

I can move the wireless keyboard, publish the results and then I'll have to pause the thread until I return (2-3 weeks)

For the Innostor Pen Drive, Usb Version: is 2.10

(ports tested: Top of PC: 1hub4 & 2hub4, Rear PC: 5hub8, 3hub8).

 

Thanks RKinner, will reply in 2-3 weeks to resume the diagnosis, Cheers!

 

Admins & Mods, please leave this thread open, I'll resume it in 2-3 weeks.

Hi RKinner, I'm back! Thanks for keeping the thread open.

What would you like me to do next?

P.S. I notice another symptom, that may or may not be related: Whenever clicking to the Safely Remove icon on system tray, It takes atleast 10 seconds for the display of devices to appear, and this includes when I have my external hdd plugged in to pc via esata.

[RKinner]

Delays are usually caused by the CPU being busy.  Does Process Explore show much CPU activity?

No. 85-95% Idle.
