Re: Am I getting USB 2.0 speed?

[Bruno Buys <brunobuys@gmail.com>]

Ok, Henrique!
Thanks, this is a very clearing info. I opened my case in the weekend, 
and found that I had removed a USB bracket that was unused, at that 
time. This one had larger wires, and a label USB 2.0 on it. So, I 
reattached it to the machine. Now, I guess the cabling is ok. But the 
tests after that were all the same. No go. The only thing that changed 
with the new bracket was the number of the 1.1 controller being used.
Its quite likely the player´s fault, because its a cheapo 1GB player. I 
wouldn´t be surprised if they lied. Here in Rio it is sold under the 
name "Starex", but google tells me its a S1, from Wilson Co, or 
whatever... Kinda obscure.
Out of curiosity: what speed do you get from USB devices? Even if this 
is 1.1 (12MB/s), I still have a way to go, from my current 800Kbps...
Regards,


Bruno
