Refresh a USB port

Topic

New Reply

Hi,

How is it possible (if indeed it is?) to refresh a USB connection without having to remove the USB device from the port? My modem is a 3G USB modem and each time I activate the modem it pops up a connection error. I then have to remove the modem from the port, reinsert it and have to go through the startup sequence again to get connected.

Can one refresh the ports connection without having to remove the device?

TX

As long as I know, the only way to refresh USB connection is unplug it and plug it in again.

However, you can avoid such problem by modifying USB settings:

– Open Device Manager (Start -> Run, type DEVMGMT.MSC and hit Enter);
– Scroll down the list until you see “Universal Serial Bus controllers” and expand it;
– Select (click on) the first “USB Root Hub” and open Properties (by right-clicking or from Acton menu);
– On the Properties window, click on Power Management tab and uncheck “Allow the computer to turn off ths device to save power” and click OK;
– Repeat the last step for all USB Root Hubs in Device Manager.
