I have a question regarding USB 1.1. My printer is a Samsung ML-1610, and it requires USB 1.1 enabled to work. Sometimes, sending print jobs would either stall the router for a minute or crash it outright. I disabled bidirectional copying and that didn't help. I've always left both OHCI and UHCI enabled. A few days ago I only enabled one of them, and so far the router hasn't crashed. Is that normal? Enabling OHCI and UHCI makes things unstable? It doesn't seem to matter which one I use; my printer works with either. What's the difference between the two? By the way this is an Asus WL-520GU running 1.27.8742. The same thing happened on older firmware builds too.
