We have a older USB device for our software that we have been running for years on Intel systems and up to the 3rd Gen i5 MB with an intel Chipset on Lenovo systems.
Lenovo has been no help .
- The Lenovo 4th Gen i5 M73 tiny has two front USB 3.0 ports and three USB 2.0 ports on the back.
- The Lenovo 3rd Gen i5M92p tiny has two front USB 3.0 ports, one USB 2.0 port on the back and two USB 3.0 ports on the back.
- Today when I configure an M92p tiny, our older USB device is plugged into one of the rear USB 3.0 ports.
As I was installing the various hardware specific drivers, I got around to our older USB device driver. The older USB device plugged is not recognized by any USB port on the M73 tiny.
When plugged into either of the front USB 3.0 ports, I get the following:
USB Device Not Recognized. "One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it.
When plugged into any of the rear USB 3.0 or 2.0 ports, I get the same message as above or the following: Unknown Device. Device driver software installed successfully.
If I try to update the driver for the USB device through Device Manager, Windows informs me that the best driver is already loaded for the device.
Now for the really weird part....
If I plug the older USB device into the DLINK USB hub (which is plugged into any of the USB 2.0 or 3.0 ports) it works properly.
This older USB device will not work is plugged into a port on the computer. For maintenance sake we need to have that as an option.
