As part of an attempt by MS to debug performance issues with my system, I performed a cold install of Win 10 Pro. Since then, all of the USB 3.0 ports on my computer run as USB 2.0. Evidence: Attaching a SONY XQD memory from my camera via the Sony reader and a USB 3.0 cable. Prior to cold install, I would see transfer speeds of appx 300 MB/s. After the cold install, transfer rates are appx 31 MB/s. Same on all USB 3.0 ports, front and rear of system. I can move the entire setup (card, reader, and cable) to any one of 4 other Win 10 computers in my house and the transfer speed is appx 300 MB/s. This tells me that it is NOT the card, the reader, or the cable.
Details: Computer: HP Z440, 32GB, AMD FirePro W5100, Win 10 ver 2004, 19041.329
Approach: I have worked with MS support on this issue for several months and they are unable to help me. Not a clue why. But anyway, I have updated the drivers, the BIOS, and everything else I can think of. I can see that USB 3.0 is not "supported" by running USBView. Here's a typical output from one of the ports. It is the same for all 8 ports:
[Port3] : USB Mass Storage Device
Is Port User Connectable: yes
Is Port Debug Capable: no
Companion Port Number: 0
Companion Hub Symbolic Link Name:
Protocols Supported:
USB 1.1: yes
USB 2.0: yes
USB 3.0: no
This issue is extremely annoying. Transfer of photographic files now takes TEN TIMES as long as it did prior to the re-install of Win10.
Need some help here.....
