There are six USB ports, two on the front of the system unit, four at the back. I always understood that these were all USB 2.0.
I have just installed a powered USB hub with seven ports. It is plugged into one of the ports at the back of the machine.
I am trying to run the following USB devices:
A powered hub with seven USB ports - no name but M.N: UH-7CY1S
Cinergy T USB XS - a DVB tuner
Oki C5450n laser printer
Sony DRX-810UL external DVD writer
Canon MP800 ink jet printer
Logitech QuickCam Fusion
Logitech Bluetooth hub connecting cordless mouse/keyboard
Occasionally I also want to use:
Another Logitech wireless keyboard/mouse sender
A different webcam
A Brother printer
A USB flash drive
SInce installing the powered hub my system has been hanging. If I boot up with the hub powered then my system hangs right at the beginning on "initializing USB controllers". If I plug it in after boot then I get all sorts of USB devoce not recognised One of teh USB devices has malfubctiuoined errosr.
I downloaded USBInfo but haven't registered it yet. It shows me that I have 1.1 controllers and 2.0 controllers and I am completely confused about what is where and how I should reconnect. Obviously I want everything on 2.0.
Then I keep on getting error messages but when I run USBReady it says everything is perfect!!!!
Can anybody help. SHall I just uninstall everything and start again? If so some guidance would be appreciated.
If someone wants to talk me through it I will of course pay for teh phone call. Just reply with your number and I'll call you.
I'm trying to attach files which show screenshots.
