serial port just stopped working today

[rogersb-lavpere]

hp laptop, was using the port on the right side near the dvd for an Arduino board.  it worked yesterday. today it wouldnt talk went thru 2 hours of changing device manager settings, looks like the serial port is smoked

isnt there a diagnostic program hp has that will test things? im not sure if the problem is settings or its a real hardware failure. i had disabled and uninstalled the serial port;  then must not have had the right version to install back in and cant find any info about it

hoped a diagnostic would find the driver. am stuck until figuring it out thanks

@rogersb-lavpere 

Are you talking about USB port ? Your machine still have 2 more USB ports have you tried them ? Arduino board is NOT from HP and I don't think HP has tested it.

Please try to use the following forum:

WEll thanks for the reply but its not helpful.  The serial port is from the USB. The arduino connects by a usb a to b cable like a printer.  There is a USB interface in the Arduino.  Millions of them out there so the levels and all should be fine.

This is a WINDOWS 10 HP laptop problem.

Its not an arduino board problem.   I could take the arduino and send it to the north pole, my HP laptop would still have a problem on this USB channel.  All other ports are used. I had usb hubs and a large plastic box of my most prized computer must-have gadgets, fittings, discs collected over 30 years. The moving company Presto Logistics STOLE IT! Along with 5 other boxes of brand new clothes and the best items in my shipment.  It included a $100 precision mouse, and stuff I wouldnt remember unless looking in that box.  Remember Presto Logistics, criminals who steal your items and there is no recourse!  I had at least 2 usb to serial adapters but this needs a USB a to b cable.  

See how the error is in device manager?Ive uninstalled and reinstalled, rebooted 3 times, changed the port from 3 to 20 or whatever, something is stuck.  Id like to clear out the driver but uninstalling/reinstalling and rebooting and it still has this same error.  

I want an HP diagnostic that runs and can reset the USB hub/port whatever to default.  Do you know of such a tool? I thought there were in the old days

There may be some Arduino issue, not sure but the problem is SOLVED!  I connected the usb to the printer, went into device manager, found the usb channel with errors and uninstalled it, also ran windows update and troubleshooter and picked PRINTER PROBLEMS.  It went in and setup the printer.  

Then I moved the usb to the Arduino and the pc made the 'new hardware found' sound, shows COM3 normal no problems

thanks
