Alright, ill tell you the full story:
I couple of days ago now i went to buy a 4 port powered usb hub.. ( i only have 2 spare ports at the back of my PC) So i plugged it in, and it seemed to work
initially, but with only one of my USB devices which was plugged into it: My ADSL modem.
When i unplugged the hub and replugged it back in, however, the hub
ceased to work. I got an error: "USB Device not Recognized. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it." In device manager it is listed as an unknown device
Furthermore, when i try to re-connect my external USB hard-drive to the original port at the back of my PC, i get the same error message. However, i do not get this error message when plugging my USB printer and ADSL modem into that same port.
Both the external harddrive and USB Hub have their own power supplies.
The hard drive was working through that port before i tried installing this hub. But now..well, it doesnt seem to like it anymore, as per that same error message. And of course the hub doesnt want to work.
I gave the hub back, and am getting a PCI USB Card for my PC. Since the ADSL Modem and Printer still work out the ports out the back, ill leave them there.
Two questions:
Why did my attempt to install the USB Hub cause this problem with my USB ports now not recognizing the external hard drive?
Should my external hard drive work with my brand new ports?
Any help would be great as this has been stressing me out
