Agree with kerplunk`s advice on choice of make
I cannot see for the life of me what difference it would make, plugging a webcam in via a USB hub no matter what make it was.
The only thing I can think of that they may have meant, was upgrading your PC to USB 2.0 if it is an older one, which would be achieved by installing a USB 2.0 card into a spare PCI slot
However, this too would have been poor advice as I believe the 150, being a very low spec . 100k model, is probably only USB 1.1 standard anyway.
