Windows 7: Extremely Slow USB ports

09 Apr 2012   #1

Windows 7 Home Premium 64bit
Extremely Slow USB ports

For the last year or so my USB ports have been running really slowly. I'm almost positive they are supposed to be USB 2.0 but I can never get speeds of more than 4mbps. This happens when I'm transferring one 4gb file, or a folder of mp3s. It happens when using a flash drive, using an external hard drive, using an SD card (or microSD) with adapter, or when plugged directly into MP3 player or Android Tablet.

So I guess I have a few questions: How do I check to make sure my ports are USB 2.0 and have the correct drivers? Am I overreacting to normal speeds or is 4mbps as slow as I think it is and if it really is slow does anybody have any suggestions for solving the problem?

Thanks for any and all help and if there is already a thread for this I apologize for wasting time and space, please point me in the direction of the correct thread. Thanks again.

Hmm, I tried that and it didin't change anything. It said everything was up to date and there was nothing to fix; but I'm still stuck at 4mb/s or less.
