This computer is running Windows 8.1. It came without USB 3. A year or so ago I added a two-port USB 3 PCIe card. I don't remember the exact brand name, but the driver is from Renesas Electronics, and it was working.
About 2 weeks ago I pulled it out and replaced it with a four-port Inateck card. I have three external drives on it and they are working fine. I did not uninstall the old card in Device Manager - I just pulled it out and put the new one in its place, and installed the drivers for the new one.
The problem is that some software takes several minutes (I estimate 3 minutes) to detect the external USB 3 drives. Two examples are SeaTools from Seagate and Parkdale HD speed test. I wrote to Seagate about this, and they said to check the drivers for the card. The drivers are up to date.
I went to Device Manager and checked all of the USB devices. They all say they are working properly. I did "check for hardware changes", but it didn't say anything about detecting a change.
I put the old card in another computer and it is working there, so I can check for details if I need to. Maybe there is a conflict between the old driver and the new one, but I don't know how to fix that.
So - how can I make the drives be detected as quickly as they should?
