multi port USB hubs question
I recently received a multi port USB hub and plugged it into my laptop. It
seemed like a good idea as I only had 2 USB ports on my computer. This gave me 4 where before I only had 1 which made a total of 5. I plugged a new external DVD burning drive into one of the multi ports ports. The drive used 2 ports, 1 for drive and 1 for drives power. I also plugged 2 external hard drives into the other 2 ports. The burning drive would not work and 1 of the external hard drives was not detected in computer. I worked on this problem all day surfing web for answers and finally got online with Microsoft support and chatted with a tech. He took control of my computer and did some troubleshooting for 3 hours. Nothing he did helped. I got to thinking about the multi port USB hub and unplugged it from computer. Then I plugged the burning drive directly into the computer using both USB ports on computer. It worked flawlessly. Is this typical of these hubs or do I just have a cheap one and need a better one. I think my ports on my computer weren't generating enough power to run all the devices. Any information on this would be very helpful. Walt |

multi port USB hubs question
Please think about what you just wrote. You have a drive that has 2 USB
connectors (to plug into 2 individual USB ports). The reason is that one USB port may not be capable of supplying sufficient to run the drive, hence the second cable. Now you plug both of these cables into a USB hub that is, in turn, connected to 1 (ONE) USB port. You are overloading the single USB port and are lucky that you didn't burn out the port on your computer. You need a USB hub with an external power supply to do what you want to do. -- Richard Urban Microsoft MVP Windows Desktop Experience & Security "Walter Goldschmidt" wrote in message ...

multi port USB hubs question
Did you USB hub have its own external power supply ? If it did not then you
have discovered your problem. If the hub is not using an external supply then ALL its power is coming from the one USB port and being divided among the ports in use. In your case you need two powered ports and with the USB hub are getting only power from one. (Hubs destined for use with desktops usually include a power plug wart thing, those destined for laptops often don't have a provision for external power.) You can get information on power available and used on USB hubs from device manager Universal Serial bus controllers the various USB Root Hub entries Michael "Walter Goldschmidt" wrote in message ...

Your replies make complete sense to me but I didn't know about hubs with
their own power supply. As a matter of fact this is the first time I've ever been involved with this device, Thanks for the education. Walt "Michael Walraven" wrote in message ...

One type is a hub that just plugs in and uses the USB too power the other USB devices that you connect to it. These are very useful when travelling since they do not have the bulky power supplies. The second type and possibly a "better" type are the powered hubs. These come with a bulky "sqarish" transformer to provide additional power to other devices. Hard drives and DVD / CD burners tend to require more power than flash drives. |
