As my number of USB devices increased, I bought a USB 2.0 hub (with external power). Unfortunately, I find that most of my USB devices won't work when they are connected to this hub, altough they work perfectly when connected directly to the PC's USB ports.
Is this normal that many device types won't work through a hub or could it be that something is wrong with my system (Win XP SP2, USB 2.0 controller onboard)?
Some of the devices not working on the hub are: DYMo LabelWriter, Lexmark X7170 MFP, Logitech Bluetooth controller, GN Netcom headset.
What do you suggest I do?
Can I add a second USB card (PCI) to my PC or is there a risk that two USB controllers get into a conflict?
