Would like to print multipaged documents on inkjet printer in quick quality mode using black ink. Have printer attached to 4-port USB hub. The printer works until it is necessary for it communicate back to the computer. Then not only does it stop printing, but I am unable to delete the job even when I disconnect the printer. When I try to uninstall the printer using the Add\Remove software facility in Windows 2000 I am told the printer is in use. When I go to Task Manager and try to stop the job from running its protected. I can reboot and delete the printer software but after I reinstall it I am back where I started. I ask Device Manager what is wrong and I am told all devices are working properly.

What seems to be missing is I don't know how to trace what files that are being accessed when I send commands to a peripheral device connected to my USB hub. So I take out Microsoft's Windows 2000 Professional Resource Kit book. Its 3" thick. So look in index and I find out that on page 1627 there is information about USB Topology. Its an overview that refers to website for more information. I feel like my life is going to be over before I findout how to monitor cummunications through my USB ports. I like to see how much bandwidth is being allocated and track the commands being sent, particularly unsolicited communication back to the computer. Can somebody help me?

I have a funny feeling that the USB isn't all that the hype they make it to be. I've attempted to connect to the internet through the USB to the Verzion DSL modem - No good. Verizon's response 99% of their help desk calls are from people using the USB to connect - recommendation use a Ethernet card and trash the USB connection.

Attempted to hook up a printer using the USB port and the communication failed on returning to the PC. Contacted HP - HP solution, use the Parralle port and trash the USB connection.

Hum - something smells in demark - that is the USB for keyboards and some other devices it appears to work OK - I don't think all manufactures have successfully done their homework with the USB ports. So call the printers manufacture and see what they say - how much you want to bet the answer is trash the USB port.

But doesn't the printer guide tell you to plug it directly into the USB port and not a Hub?

As you didn't say what type of hub it is I'm at best only guessing here but if it is the unpowered type maybe it doesn't support bidirectional communication so that could be your problem as that is exactly what would happen with your description of the problem. Also most of the USB enabled printers are USB 2 and if it is connected through a USB 1 port it may not work correctly either.
