Query: Simple to install. Automatic & Transparent in operation.

PC is an Apple Power Mac G4 (Quicksilver, c. 2001), Dual 800MHz CPU, 1.5GB RAM, 80GB HDD, USB 1 and Firewire 400.Mac OS X 10.4.11 (Tiger).Physical installation was simple; open the de-energized case, plug in & secure the adapter card--no problem.On power up the Sonnet Allegro was detected and installed automatically, no CD needed, nor anything else--no problem.Three devices plugged into the Sonnet Allegro: A-Power External Backup HDD; Canon Scanner; HP Laser Printer. No problems.PC has been put to sleep and awakened several times--no problem.Keyboard is still on the native USB 1 hub--no problem.This is not proof that a problem will never arise--but after 1 month of operation no problem has been noticed.The Sonnet Allegro has a "quality" look & feel--but again, this is just my impression, not a guarantee.Purchased direct from amazon.com.Enjoy.
