Hi,
....Most of the problems I've had were with USB
devices
plugged into the front USB ports - because of the length
(and poor quality) of the cable inside the machine, they'd
work at 12Mbit for a flashdrive, but as soon as you go up to
480Mbit (especially with something like a scanner), the data
just gets mangled.
The biggest problem I've found with front mounted ports is that the USB
standard is so brain dead that if you plug in a USB2.0 device into such a
port, and the cable quality is bad, the damn thing refuses to fall back to
USB1 data rates when it fails to communicate at USB2 rates. So you end up
with a non-working, "unidentified" device. :-(
99% of the problems I've had with USB could be
traced back to bad
grounding, bad cable or a combination of the two.
100% of the problems I've had with USB stem from the bad design of the
interface....
Can't you tell I just *LOVE* USB? ;-)
The main reason I'm using USB is speed....
If that's your main reason for using USB then you really should consider
using FireWire instead.
I recall reading up on FireWire vs USB a few years ago before I standardised
on FireWire. Despite being marginally slower in terms of bit rate, FireWire
offers something like 20% more throughput than USB2.
TTFN - Pete.
