Testing Internal USB Hub

Post by MichaelJohn »

One project uses an external USB hub connected to between four and nine sensors with USB connectivity. We used to have numerous USB errors that were eventually traced to the external USB hub. Upgrading these to a better quality hub (there is a lot of carp for sale out there) solved the problem. Now though I think I have an internal USB hub problem on a DELL Vostro 1015 the external hub and sensors work correctly on another laptop whereas those from the other laptop do not work on the original laptop.

Is there a way I can test the internal USB hub (preferably with repeated accesses) under Mint 17.3? Everything I have found on the web refers to Windowz operating systems! :(

Not sure if I am fully following the issue. Are the USB ports not working at all or is it just the hub that's not working?

How much current do the sensors draw? A USB port is supposed to be able to provide a half amp. Could the sensors draw more than that? That can cause problems.
