Title: IBM Model M with Lenovo t530 and Windows 8
Post by: charrington on Tue, 16 April 2013, 01:28:03
First, I've been away from this site for too long. Is good to be back!

I got a new PC - Lenovo t530 and Windows 8. Just getting setup.  I've got one of my Model M keyboards plugged into a USB port using a Ziotek adapter (several years old - not sure if they've changed).  When I boot Windows, the keyboard flashes (sometimes NumLock stays on) but the keyboard won't respond unless I unplug it and then plug it back in. The particular Model M I tried was made March 1990.

Do you have it plugged into a USB-3 port?  Try a USB-2 port instead.

This should not be a problem the USB-3 port would downgrade it to a USB-2 port.

It "should not" be a problem.  However, I have a Thinkpad W520 and it acts the exact same way when the keyboard is plugged into the USB-3 .  USB-2 - no problem.

That's odd... does it work with other USB-2 devices?

From what I recall, other stuff with that port (mouse, printers, external drives) all worked fine.  Just the keyboard with the bluecube acted funky.  Thinking back, I think on a cold boot it worked fine.  On a resume from hibernation it always happened.

Switched ports, hasn't been a problem since.   Haven't investigated it any further than that.

I occasionally have problems with USB 3.0 ports acting funky also. I can get things to wrok in USB 2 ports, but not USB 3.0

Hmmm... have you tried turning it off and on again?

My Model M has trouble waking up from hibernation from the powered USB 2.0 port (Windows 7).  But after I moved it to a normal USB 2.0 port, it works perfectly.

So I guess the good old USB 2.0 is the best friend of old keyboards?
