Similarly, I assume that a USB 1 device will work on a USB 2 port with the same speed restriction. That sound right, or am I whistling Dixie? Cheers Billy 8-{) :confused:	Billy T (70)
425531	2006-01-31 01:41:00	That sounds right Billy. Either way will work, but at the slower USB 1.1 speed	Speedy Gonzales (78)

425533	2006-01-31 02:04:00	And you'll never know the difference ... there aren't many printers fast enough to be waiting on the 1.1 speed. :D	Graham L (2)
425534	2006-01-31 02:08:00	Thats correct, USB2 is in two flavours, Full Speed and high speed, One of which is really USB1, This is for teh sole reason that they can brand a printer as USB2, even though it is identical to the model it replaced that was simply USB. Anyhow, A printer won't max out either connection, so data transfer will be at teh rate the device can work at, You could plug her in an optical port and the process would still take the same amount of time. (that doesn't mean any sparty pants should now go ahead and calculate how incorrect that statement is by measuring teh planets, deviding by the speed of their orbits and applying that to the data rate of an optical cable multiplied by the voltage of a usb connection)	Metla (12)
