I sold this client and ASUS AMD870 chipset based motherboard with USB 3.
Now....He has this external 1TB samsung hard drive and an old kyocera 1200D printer that sometimes is not recognize even if he turn the computer off and then back on. only plugging them out of the usb and then back in brings them to life.....
I'm afraid it has to do something with he fairly new usb 3 chipset but not sure.
This computer also has a non powered usb hub connected to one of its rear usb.
How would you suggest to test to check the cause of the problem ?
