Hello --- My laptop just has 2 usb 3.x ports ---   One is  a type-a   port the other type-c  ----  Since there is just the one A port I been  using a hub  --- a powered hub  ---  connected to the A port 

 

It seems to work most of the time, but when I was copying  large files 10g+ copy just stopped ---- If  connect the drive directly to the A Port the copy works fine ---- is there any way to debug this issue?  Thanks

@fpefpe 

According to the HP spec sheet for the model number you provided, there are four USB ports: USB 3.0, USB-C, USB 2.0 (2).

 

USB 2x and 3x have different speeds but USB-C is only a connection spec, not a speed spec.  And the spec sheet does not way whether the underlying USB speed is 2x or 3x.  So, connecting a hub to that might be a performance issue when you are trying to load the channel heavily.

Thanks for your reply --- I have a drive directly connected to the usb-c port --- I am assuming that the usb-c port is usb 3.1 --- but the hub is connected to the usb 3.0 (typ-a) port  -- in the case when the copy just stopped  there was just one drive plugged into the hub
